core: Rewrite some of the A/V sync related code Notable functionality changes: * Timing change between any two frames is now accurately limited to 1/10 of their nominal distance. Previous code did not always use the correct duration. * The status line now keeps showing the same A-V sync value from one video frame change to the next. Previously it kept recalculating the value using a new audio position but the same video position when the status line was updated between video frames. This incorrectly showed the video losing sync with audio. * The status line now displays actual measured A-V difference in autosync mode too. The previous code displayed values that completely ignored real timing in autosync mode, showing 0 A-V difference even when video was significantly behind audio due to inadequate decoding speed. The new behavior can make the shown A-V values appear more unstable if the audio out has unreliable delay measurements (the most likely reason to use autosync), but this is a display change rather than a timing quality change. * Autosync mode now tries to adjust timing by the amount of time vo_flip() calls take, so the calls start earlier and finish at the time the frame should be shown. Previously non-autosync mode adjusted for this but autosync did not. * The warning about the system being too slow to decode the video in realtime is now displayed in autosync mode too.

Move options/config related files from mpvcore/ to options/ Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok.

sub: uglify OSD code path with locking Do two things: 1. add locking to struct osd_state 2. make struct osd_state opaque While 1. is somewhat simple, 2. is quite horrible. Lots of code accesses lots of osd_state (and osd_object) members. To make sure everything is accessed synchronously, I prefer making osd_state opaque, even if it means adding pretty dumb accessors. All of this is meant to allow running VO in their own threads. Eventually, VOs will request OSD on their own, which means osd_state will be accessed from foreign threads.

// definitions used internally by the core player code
core: Clean up move-to-next-file logic The mpctx->eof field was used to also store other reasons to stop playing the current file besides EOF, and the code didn't properly distinguish those from EOF. Rename the field to "stop_play" and clean up some of the code accessing it. Properly separating EOF from other reasons allows handling file switching better. Before this commit buffered audio was always drained before moving to the next file (the only exception when it was NOT drained when stopping a file was when quitting the player completely). This added an extra delay when manually moving to the next file as you had to wait for the currently buffered audio to finish playing before the next file would start. After this commit audio is only drained if the file reaches EOF normally; otherwise audio is cut and the next file starts immediately.

mplayer: turn playtree into a list, and change per-file option handling Summary: - There is no playtree anymore. It's reduced to a simple list. - Options are now always global. You can still have per-file options, but these are optional and require special syntax. - The slave command pt_step has been removed, and playlist_next and playlist_prev added. (See etc/input.conf changes.) This is a user visible incompatible change, and will break slave-mode applications. - The pt_clear slave command is renamed to playlist_clear. - Playtree entries could have multiple files. This is not the case anymore, and playlist entries have always exactly one entry. Whenever something adds more than one file (like ASX playlists or dvd:// or dvdnav:// on the command line), all files are added as separate playlist entries. Note that some of the changes are quite deep and violent. Expect regressions. The playlist parsing code in particular is of low quality. I didn't try to improve it, and merely spent to least effort necessary to keep it somehow working. (Especially ASX playlist handling.) The playtree code was complicated and bloated. It was also barely used. Most users don't even know that mplayer manages the playlist as tree, or how to use it. The most obscure features was probably specifying a tree on command line (with '{' and '}' to create/close tree nodes). It filled the player code with complexity and confused users with weird slave commands like pt_up. Replace the playtree with a simple flat playlist. Playlist parsers that actually return trees are changed to append all files to the playlist pre-order. It used to be the responsibility of the playtree code to change per-file config options. Now this is done by the player core, and the playlist code is free of such details. Options are not per-file by default anymore. This was a very obscure and complicated feature that confused even experienced users. Consider the following command line: mplayer file1.mkv file2.mkv --no-audio file3.mkv This will disable the audio for file2.mkv only, because options are per-file by default. To make the option affect all files, you're supposed to put it before the first file. This is bad, because normally you don't need per-file options. They are very rarely needed, and the only reasonable use cases I can imagine are use of the encode backend (mplayer encode branch), or for debugging. The normal use case is made harder, and the feature is perceived as bug. Even worse, correct usage is hard to explain for users. Make all options global by default. The position of an option isn't significant anymore (except for options that compensate each other, consider --shuffle --no-shuffle). One other important change is that no options are reset anymore if a new file is started. If you change settings with slave mode commands, they will not be changed by playing a new file. (Exceptions include settings that are too file specific, like audio/subtitle stream selection.) There is still some need for per-file options. Debugging and encoding are use cases that profit from per-file options. Per-file profiles (as well as per-protocol and per-VO/AO options) need the implementation related mechanisms to backup and restore options when the playback file changes. Simplify the save-slot stuff, which is possible because there is no hierarchical play tree anymore. Now there's a simple backup field. Add a way to specify per-file options on command line. Example: mplayer f1.mkv -o0 --{ -o1 f2.mkv -o2 f3.mkv --} f4.mkv -o3 will have the following options per file set: f1.mkv, f4.mkv: -o0 -o3 f2.mkv, f3.mkv: -o0 -o3 -o1 -o2 The options --{ and --} start and end per-file options. All files inside the { } will be affected by the options equally (similar to how global options and multiple files are handled). When playback of a file starts, the per-file options are set according to the command line. When playback ends, the per-file options are restored to the values when playback started.

mplayer: attempt to skip playlist entries which can't be played This is for situations when repeated attempts at playing a playlist entry failed, and playlist navigation becomes impossible due to that. For example, it wasn't possible to skip backwards past an unplayable playlist entry: mpv file1.mkv doesntexist.mkv file3.mkv You couldn't skip back to file1.mkv from file3.mkv. When running a single "playlist_prev" command, doesntexist.mkv would be played, which would fail to load. As reaction to the failure to load it, the next file would be played, which is file3.mkv. To make this even worse, the file could successfully load, but run only for a split second. So just loading successfully isn't good enough. Attempt to solve this by marking problematic playlist entries as failed, and by having playlist_prev skip past such playlist entries. We define failure as not being able to play more than 3 seconds (or failing to initialize to begin with). (The 3 seconds are in real time, not file duration.) "playlist_prev force" still exhibits the old behavior. Additionally, use the same mechanism to prevent pointless infinite reloading if none of the files on the playlist exist. (See github issue All in all, this is a heuristic, and later adjustments might be necessary. Note: forward skips (playlist_next) are not affected at all. (Except for the interaction with --loop.)

core: runtime Matroska edition switching Add a new slave property which switches the current Matroska edition. Since each edition can define an entirely new timeline, switching the edition will simply restart playback at the beginning of the file with the new edition selected. Add 'E' as new keybinding to step the edition property. DVD titles are still separate. Apparently they work similarly, but I don't have any multi-title DVDs for testing. Also, cdda (for audio CDs) uses the same mechanism as DVDs to report a number of titles, so there seems to be confusion what exactly this mechanism is supposed to do. That's why the edition code is completely separate for now. Remove demuxer.num_titles. It was just a rather useless cache for the return value of the DVD titles related STREAM_CTRL. One rather obscure corner case isn't taken care of: if the ordered chapters file has file local options set, they are reset on playback restart. This is unexpected, because edition switching is meant to behave like seeking back to the beginning of the file.

PT_RESTART, // restart previous file
Add prelimimary (basic, possibly broken) dvdnav support This readds a more or less completely new dvdnav implementation, though it's based on the code from before commit 41fbcee. Note that this is rather basic, and might be broken or not quite usable in many cases. Most importantly, navigation highlights are not correctly implemented. This would require changes in the FFmpeg dvdsub decoder (to apply a different internal CLUT), so supporting it is not really possible right now. And in fact, I don't think I ever want to support it, because it's a very small gain for a lot of work. Instead, mpv will display fake highlights, which are an approximate bounding box around the real highlights. Some things like mouse input or switching audio/subtitles stream using the dvdnav VM are not supported. Might be quite fragile on transitions: if dvdnav initiates a transition, and doesn't give us enough mpeg data to initialize video playback, the player will just quit. This is added only because some users seem to want it. I don't intend to make mpv a good DVD player, so the very basic minimum will have to do. How about you just convert your DVD to proper video files?

PT_RELOAD_DEMUXER, // restart playback, but keep stream open
mplayer: never exit mplayer from within the play loop The only place exit_player() should be called is the main() function. exit_player() should be the only function allowed to call exit(). This makes it easier to guarantee proper deinitialization, and allows using the --leak-report flag without showing false positives. The quit slave command now sets a flag only. It uses the same mechanism that's normally used to advance to the next file on the playlist, so the rest of the playback path should be able to react to the quit command quickly enough. That is, the player should react just as fast to quit requests in practice as before this commit. In reinit_audio_chain(), the player was actually exited if init_audio_filters() failed. Reuse the normal error handling path to handle this condition.

Rename the field to "stop_play" and clean up some of the code accessing it. Properly separating EOF from other reasons allows handling file switching better. Before this commit buffered audio was always drained before moving to the next file (the only exception when it was NOT drained when stopping a file was when quitting the player completely). This added an extra delay when manually moving to the next file as you had to wait for the currently buffered audio to finish playing before the next file would start. After this commit audio is only drained if the file reaches EOF normally; otherwise audio is cut and the next file starts immediately.

core: manage tracks in the frontend Introduce a general track struct for every audio/video/subtitle track known to the frontend. External files (subtitles) are now represented as tracks too.

The default behavior doesn't change (images are displayed). Identify video streams, that are actually image attachments, with "[P]" in the terminal output. Modify the default stream selection such that real video streams are preferred over attached pictures. (This is just for robustness; I do not know of any samples where images are added before actual video streams and could lead to bad default stream selection with the old code.)

core: manage tracks in the frontend Introduce a general track struct for every audio/video/subtitle track known to the frontend. External files (subtitles) are now represented as tracks too. This mainly serves to clean up the subtitle selection code: now every subtitle is simply a track, instead of using a messy numbering that goes by subtitle type (as it was stored in the global_sub_pos field). The mplayer fontend will list external subtitle files as additional tracks. The timeline code now tries to match the exact demuxer IDs of all tracks. This may cause problems when Matroska files with different track numberings are used with EDL timelines. Change demux_lavf not to set demuxer IDs, since most time they are not set.

player: don't select subtitles added from quvi by default Quvi subtitles are considered external subtitles (simply because they're separate from the audio/video stream), but for the sake of subtitle auto-selection, they should not be considered external. Change this so that quvi subtitles are treated like muxed subtitles (with default flag never set). This means subtitles won't be selected by default, unless explicitly requested with --sid or --slang.

Fix the -subfile case, and make the behavior consistent by making the selection behavior explicit.

player: fix regression with ordered chapters Broken by commit 1301a907. This commit added demuxer threading, and changed some other things to make them simpler and more orthogonal. One of these things was ntofications about streams that appear during playback. That's an obscure corner case, but the change made handling of it as natural as normal initialization. This didn't work for two reasons: 1. When playing an ordered chapters file where the initial segment was not from the main file, its streams were added to the track list. So they were printed twice, and switching to the next segment didn't work, because the right streams were not selected. 2. EDL, CUE, as well as possibly certain Matroska files don't have any data or tracks in the "main" demuxer, so normally the first segment is picked for the track list. This was simply broken. Fix by sprinkling the code with various hacks.

core: add demux_sub pseudo demuxer Subtitle files are opened in mplayer.c, not using the demuxer infrastructure in general. Pretend that this is not the case (outside of the loading code) by opening a pseudo demuxer that does nothing. One advantage is that the initialization code is now the same, and there's no confusion about what the difference between track->stream, track->sh_sub and mpctx->sh_sub is supposed to be. This is a bit stupid, and it would be much better if there were proper subtitle demuxers (there are many in recent FFmpeg, but not Libav). So for now this is just a transition to a more proper architecture. Look at demux_sub like an artifical limb: it's ugly, but don't hate it - it helps you to get on with your life.

audio: change playback restart and resyncing This commit makes audio decoding non-blocking. If e.g. the network is too slow the playloop will just go to sleep, instead of blocking until enough data is available. For video, this was already done with commit 7083f88c. For audio, it's unfortunately much more complicated, because the audio decoder was used in a blocking manner. Large changes are required to get around this. The whole playback restart mechanism must be turned into a statemachine, especially since it has close interactions with video restart. Lots of video code is thus also changed. (For the record, I don't think switching this code to threads would make this conceptually easier: the code would still have to deal with external input while blocked, so these in-between states do get visible [and thus need to be handled] anyway. On the other hand, it certainly should be possible to modularize this code a bit better.) This will probably cause a bunch of regressions.

Getting rid of all the MSGT_* constants and the inconsistent prefixes spread throughout the source code. Both goals are not immediately reached with this commit. It's a huge transition that will take time. There are over >2500 mp_msg calls in the source, which all have to be replaced for this to work. The inconsistent prefixes are in particular annoying. Lots of code manually prefixes messages, e.g. mp_msg(MSGT_VO, MSGL_V, "[vo] ..."). Sometimes the prefixes don't even follow this convention (for example vo_direct3d.c uses "<vo_direct3d>" as prefix). This commit allows automatically adding prefixes on request, so consistency will hopefully improve. For now, this commit adds unused stuff, and behavior should not change.

stream: redo playback abort handling This mechanism originates from MPlayer's way of dealing with blocking network, but it's still useful. On opening and closing, mpv waits for network synchronously, and also some obscure commands and use-cases can lead to such blocking. In these situations, the stream is asynchronously forced to stop by "interrupting" it. The old design interrupting I/O was a bit broken: polling with a callback, instead of actively interrupting it. Change the direction of this. There is no callback anymore, and the player calls mp_cancel_trigger() to force the stream to return. libavformat (via stream_lavf.c) has the old broken design, and fixing it would require fixing libavformat, which won't happen so quickly. So we have to keep that part. But everything above the stream layer is prepared for a better design, and more sophisticated methods than mp_cancel_test() could be easily introduced. There's still one problem: commands are still run in the central playback loop, which we assume can block on I/O in the worst case. That's not a problem yet, because we simply mark some commands as being able to stop playback of the current file ("quit" etc.), so input.c could abort playback as soon as such a command is queued. But there are also commands abort playback only conditionally, and the logic for that is in the playback core and thus "unreachable". For example, "playlist_next" aborts playback only if there's a next file. We don't want it to always abort playback. As a quite ugly hack, abort playback only if at least 2 abort commands are queued - this pretty much happens only if the core is frozen and doesn't react to input.

Create a context struct for OSD state This commit creates the struct and passes it to some functions that needs to access OSD state but does not yet move much data from globals to it. vf_expand accesses the OSD state for rendering purposes outside of the normal OSD draw time. The way this currently works is suboptimal, but I did not attempt to clean it up now. To keep things working the same way vf_expand needs to know the address of the state object to be able to access the data even in the functions that should normally not need it. For that purpose this commit adds a VFCTRL to tell vf_expand the address of the object.

player: redo terminal OSD and status line handling The terminal OSD code includes the handling of the terminal status line, showing player OSD messages on the terminal, and showing subtitles on terminal (the latter two only if there is no video window, or if terminal OSD is forced). This didn't handle some corner cases correctly. For example, showing an OSD message on the terminal always cleared the previous line, even if the line was an important message (or even just the command prompt, if most other messages were silenced). Attempt to handle this correctly by keeping track of how many lines the terminal OSD currently consists of. Since there could be race conditions with other messages being printed, implement this in msg.c. Now msg.c expects that MSGL_STATUS messages rewrite the status line, so the caller is forced to use a single mp_msg() call to set the status line. Instead of littering print_status() all over the place, update the status only once per playloop iteration in update_osd_msg(). In audio- only mode, the status line might now be a little bit off, but it's perhaps ok. Print the status line only if it has changed, or if another message was printed. This might help with extremely slow terminals, although in audio+video mode, it'll still be updated very often (A-V sync display changes on every frame). Instead of hardcoding the terminal sequences, use terminfo/termcap to get the sequences. Remove the --term-osd-esc option, which allowed to override the hardcoded escapes - it's useless now. The fallback for terminals with no escape sequences for moving the cursor and clearing a line is removed. This somewhat breaks status line display on these terminals, including the MS Windows console: instead of querying the terminal size and clearing the line manually by padding the output with spaces, the line is simply not cleared. I don't expect this to be a problem on UNIX, and on MS Windows we could emulate escape sequences. Note that terminal OSD (other than the status line) was broken anyway on these terminals. In osd.c, the function get_term_width() is not used anymore, so remove it. To remind us that the MS Windows console apparently adds a line break when writint the last column, adjust screen_width in terminal- win.c accordingly.

The main reason for that was the code clearing the OSD bar is also responsible for clearing the osd_function (which stores the playback symbol). If no OSD bar was set, the osd_function was never reset. Fix by always setting the timer for clearing the OSD bar and the osd_function whenever the osd_function is set. Clearing the OSD bar when it wasn't set is OK. If the OSD bar is set some time after osd_function is set, the timer is overwritten - that's a good thing, as it makes both disappear from the screen at exactly the same time. Always reset osd_function to 0 and determine the playback status explicitly from mpctx->paused when displaying the status on screen.

mplayer: turn playtree into a list, and change per-file option handling Summary: - There is no playtree anymore. It's reduced to a simple list. - Options are now always global. You can still have per-file options, but these are optional and require special syntax. - The slave command pt_step has been removed, and playlist_next and playlist_prev added. (See etc/input.conf changes.) This is a user visible incompatible change, and will break slave-mode applications. - The pt_clear slave command is renamed to playlist_clear. - Playtree entries could have multiple files. This is not the case anymore, and playlist entries have always exactly one entry. Whenever something adds more than one file (like ASX playlists or dvd:// or dvdnav:// on the command line), all files are added as separate playlist entries. Note that some of the changes are quite deep and violent. Expect regressions. The playlist parsing code in particular is of low quality. I didn't try to improve it, and merely spent to least effort necessary to keep it somehow working. (Especially ASX playlist handling.) The playtree code was complicated and bloated. It was also barely used. Most users don't even know that mplayer manages the playlist as tree, or how to use it. The most obscure features was probably specifying a tree on command line (with '{' and '}' to create/close tree nodes). It filled the player code with complexity and confused users with weird slave commands like pt_up. Replace the playtree with a simple flat playlist. Playlist parsers that actually return trees are changed to append all files to the playlist pre-order. It used to be the responsibility of the playtree code to change per-file config options. Now this is done by the player core, and the playlist code is free of such details. Options are not per-file by default anymore. This was a very obscure and complicated feature that confused even experienced users. Consider the following command line: mplayer file1.mkv file2.mkv --no-audio file3.mkv This will disable the audio for file2.mkv only, because options are per-file by default. To make the option affect all files, you're supposed to put it before the first file. This is bad, because normally you don't need per-file options. They are very rarely needed, and the only reasonable use cases I can imagine are use of the encode backend (mplayer encode branch), or for debugging. The normal use case is made harder, and the feature is perceived as bug. Even worse, correct usage is hard to explain for users. Make all options global by default. The position of an option isn't significant anymore (except for options that compensate each other, consider --shuffle --no-shuffle). One other important change is that no options are reset anymore if a new file is started. If you change settings with slave mode commands, they will not be changed by playing a new file. (Exceptions include settings that are too file specific, like audio/subtitle stream selection.) There is still some need for per-file options. Debugging and encoding are use cases that profit from per-file options. Per-file profiles (as well as per-protocol and per-VO/AO options) need the implementation related mechanisms to backup and restore options when the playback file changes. Simplify the save-slot stuff, which is possible because there is no hierarchical play tree anymore. Now there's a simple backup field. Add a way to specify per-file options on command line. Example: mplayer f1.mkv -o0 --{ -o1 f2.mkv -o2 f3.mkv --} f4.mkv -o3 will have the following options per file set: f1.mkv, f4.mkv: -o0 -o3 f2.mkv, f3.mkv: -o0 -o3 -o1 -o2 The options --{ and --} start and end per-file options. All files inside the { } will be affected by the options equally (similar to how global options and multiple files are handled). When playback of a file starts, the per-file options are set according to the command line. When playback ends, the per-file options are restored to the values when playback started.

struct playlist *playlist;
player: deal with some corner cases with playlist navigation The purpose is making accessing the current playlist entry saner when commands are executed during initialization, termination, or after playlist navigation commands. For example, the "playlist_remove current" command will invalidate playlist->current - but some things still access the playlist entry even on uninit. Until now, checking stop_play implicitly took care of it, so it worked, but it was still messy. Introduce the mpctx->playing field, which points to the current playlist entry, even if the entry was removed and/or the playlist's current entry was moved (e.g. due to playlist navigation).

player: open stream and demuxer asynchronously Run opening the stream and opening the demuxer in a separate thread. This should remove the last code paths in which the player can normally get blocked on network. When the stream is opened, the player will still react to input and so on. Commands to abort opening can also be handled properly, instead of using some of the old hacks in input.c. The only thing the user can really do is aborting loading by navigating the playlist or quitting. Whether playback abort works depends on the stream implementation; with normal network, this will depend on what libavformat (via "interrupt" callback) does. Some pain is caused by DVD/BD/DVB. These want to reload the demuxer sometimes. DVB wants it in order to discard old, inactive streams. DVD/BD for the same reason, and also for reloading stream languages and similar metadata. This means the stream and the demuxer have to be loaded separately. One minor detail is that we now need to copy all global options. This wasn't really needed before, because the options were accessed on opening only, but since opening is now on a separate thread, this obviously becomes a necessity.

command: add a mechanism to allow scripts to intercept file loads A vague idea to get something similar what libquvi did. Undocumented because it might change a lot, or even be removed. To give an idea what it does, a Lua script could do the following: -- type ID priority mp.commandv("hook_add", "on_load", 0, 0) mp.register_script_message("hook_run", function(param, param2) -- param is "0", the user-chosen ID from the hook_add command -- param2 is the magic value that has to be passed to finish -- the hook mp.resume_all() -- do something, maybe set options that are reset on end: mp.set_property("file-local-options/name", "value") -- or change the URL that's being opened: local url = mp.get_property("stream-open-filename") mp.set_property("stream-open-filename", url .. ".png") -- let the player (or the next script) continue mp.commandv("hook_ack", param2) end)

core: show quvi page title in window title, clean up libquvi handling Clean up handling of libquvi (which resolves URLs of streaming sites into URLs to the actual media playable by mpv). Move the code out of open.c to quvi.c, and invoke it explicitly from mplayer.c, instead of trying to resolve every filename passed to open_stream(). This allows easily passing metadata from the quvi context to the frontend. Expose QUVIPROP_PAGETITLE as "media-title" property, and use that instead of "filename" for the mplayer window title. (For YouTube, this is the video title.) It's cleaner too. Handle a potential reliability issue: check quvi_getprop return values. Since open.c contains barely anything but the open_stream() stub, move that to stream.c and delete open.c.

struct mp_resolve_result *resolve_result;
core: Clean up move-to-next-file logic The mpctx->eof field was used to also store other reasons to stop playing the current file besides EOF, and the code didn't properly distinguish those from EOF. Rename the field to "stop_play" and clean up some of the code accessing it. Properly separating EOF from other reasons allows handling file switching better. Before this commit buffered audio was always drained before moving to the next file (the only exception when it was NOT drained when stopping a file was when quitting the player completely). This added an extra delay when manually moving to the next file as you had to wait for the currently buffered audio to finish playing before the next file would start. After this commit audio is only drained if the file reaches EOF normally; otherwise audio is cut and the next file starts immediately.

player: remove central uninit_player() function and flags mess Each subsystem (or similar thing) had an INITIALIZED_ flag assigned. The main use of this was that you could pass a bitmask of these flags to uninit_player(). Except in some situations where you wanted to uninitialize nearly everything, this wasn't really useful. Moreover, it was quite annoying that subsystems had most of the code in a specific file, but the uninit code in loadfile.c (because that's where uninit_player() was implemented). Simplify all this. Remove the flags; e.g. instead of testing for the INITIALIZED_AO flag, test whether mpctx->ao is set. Move uninit code to separate functions, e.g. uninit_audio_out().

This makes it easier to guarantee proper deinitialization, and allows using the --leak-report flag without showing false positives. The quit slave command now sets a flag only. It uses the same mechanism that's normally used to advance to the next file on the playlist, so the rest of the playback path should be able to react to the quit command quickly enough. That is, the player should react just as fast to quit requests in practice as before this commit. In reinit_audio_chain(), the player was actually exited if init_audio_filters() failed. Reuse the normal error handling path to handle this condition.

config: don't save options to resume-config that didn't change This is approximate: we read each option value on program start (before starting playback of a file), and when writing the resume config, compare each value to the current state. This also means when a value is changed and then changed back, it's not stored. In particular, option values set in config files and on the command line are considered the default. This should help reducing the numbers of options overridden by the resume config. If too much is overridden, it becomes an inconvenience, because changes in config files will apparently have no effect when resuming a file. Also see github issue #574.

mplayer: fix looping of very short files Commit 884c179 attempted to make it possible to skip backwards through the playlist, even for files which fail to intitialize, or play for a very short time. This was also used to prevent mpv from looping forever and doing nothing if --loop=inf is used, and no file in the playlist is playable. This broke looping of very short files, because mpv was assuming that this case happened. But there are legitimate use cases. Fix this by making the looping case special. Instead of checking whether playback was "very short", check whether something could be decoded and displayed/played. If yes, allow looping.

Add initial Lua scripting support This is preliminary. There are still tons of issues, and any aspect of scripting may change in the future. I decided to merge this (preliminary) work now because it makes it easier to develop it, not because it's done. lua.rst is clear enough about it (plus some sarcasm). This requires linking to Lua. Lua has no official pkg-config file, but there are distribution specific .pc files, all with different names. Adding a non-pkg-config based configure test was considered, but we'd rather not. One major complication is that libquvi links against Lua too, and if the Lua version is different from mpv's, you will get a crash as soon as libquvi uses Lua. (libquvi by design always runs when a file is opened.) I would consider this the problem of distros and whoever builds mpv, but to make things easier for users, we add a terrible runtime test to the configure script, which probes whether libquvi will crash. This is disabled when cross-compiling, but in that case we hope the user knows what he is doing.

If a timeline is used, the master_demuxer will still refer to the main file, instead to segments. Instead of mpctx->demuxer->stream, access mpctx->stream; even though they are the same, the code becomes shorter. For the TV code, introduce a function get_tvh() to access the TV handle, instead of duplicating the code all over the place. Often the demuxer field is checked to determine whether something is currently played; prefer other methods over that.

One of these things was ntofications about streams that appear during playback. That's an obscure corner case, but the change made handling of it as natural as normal initialization. This didn't work for two reasons: 1. When playing an ordered chapters file where the initial segment was not from the main file, its streams were added to the track list. So they were printed twice, and switching to the next segment didn't work, because the right streams were not selected. 2. EDL, CUE, as well as possibly certain Matroska files don't have any data or tracks in the "main" demuxer, so normally the first segment is picked for the track list. This was simply broken. Fix by sprinkling the code with various hacks.

The consequence is that it might do not-gapless playback in more cases when needed, but if that bothers you, you still can use the normal gapless mode.

video: fix and simplify video format changes and last frame display The previous commit broke these things, and fixing them is separate in this commit in order to reduce the volume of changes. Move the image queue from the VO to the playback core. The image queue is a remnant of the old way how vdpau was implemented, and increasingly became more and more an artifact. In the end, it did only one thing: computing the duration of the current frame. This was done by taking the PTS difference between the current and the future frame. We keep this, but by moving it out of the VO, we don't have to special-case format changes anymore. This simplifies the code a lot. Since we need the queue to compute the duration only, a queue size larger than 2 makes no sense, and we can hardcode that. Also change how the last frame is handled. The last frame is a bit of a problem, because video timing works by showing one frame after another, which makes it a special case. Make the VO provide a function to notify us when the frame is done, instead. The frame duration is used for that. This is not perfect. For example, changing playback speed during the last frame doesn't update the end time. Pausing will not stop the clock that times the last frame. But I don't think this matters for such a corner case.

audio: change playback restart and resyncing This commit makes audio decoding non-blocking. If e.g. the network is too slow the playloop will just go to sleep, instead of blocking until enough data is available. For video, this was already done with commit 7083f88c. For audio, it's unfortunately much more complicated, because the audio decoder was used in a blocking manner. Large changes are required to get around this. The whole playback restart mechanism must be turned into a statemachine, especially since it has close interactions with video restart. Lots of video code is thus also changed. (For the record, I don't think switching this code to threads would make this conceptually easier: the code would still have to deal with external input while blocked, so these in-between states do get visible [and thus need to be handled] anyway. On the other hand, it certainly should be possible to modularize this code a bit better.) This will probably cause a bunch of regressions.

core: completely change handling of attached picture pseudo video Before this commit, we tried to play along with libavformat and tried to pretend that attached pictures are video streams with a single frame, and that the frame magically appeared at the seek position when seeking. The playback core would then switch to a mode where the video has ended, and the "remaining" audio is played. This didn't work very well: - we needed a hack in demux.c, because we tried to read more packets in order to find the "next" video frame (libavformat doesn't tell us if a stream has ended) - switching the video stream didn't work, because we can't tell libavformat to send the packet again - seeking and resuming after was hacky (for some reason libavformat sets the returned packet's PTS to that of the previously returned audio packet in generic code not related to attached pictures, and this happened to work) - if the user did something stupid and e.g. inserted a deinterlacer by default, a picture was never displayed, only an inactive VO window) - same when using a command that reconfigured the VO (like switching aspect or video filters) - hr-seek didn't work For this reason, handle attached pictures as separate case with a separate video decoding function, which doesn't read packets. Also, do not synchronize audio to video start in this case.

core: add support for precise non-keyframe-limited seeks Add support for seeking to an arbitrary non-keyframe position by decoding video starting from the previous keyframe. Whether to use this functionality when seeking is controlled by the new option -hr-seek and a new third argument to the "seek" command. The default is to use it for absolute seeks (like chapter seeks) but not for relative ones. Because there's currently no support for cutting encoded audio some desync is expected if encoded audio passthrough is used. Currently precise seeks always go to the first frame with timestamp equal to or greater than the target position; there's no support for "matching or earlier" backwards seeks at frame level.

Replace all calls to GetTimer()/GetTimerMS() GetTimer() is generally replaced with mp_time_us(). Both calls return microseconds, but the latter uses int64_t, us defined to never wrap, and never returns 0 or negative values. GetTimerMS() has no direct replacement. Instead the other functions are used. For some code, switch to mp_time_sec(), which returns the time as double float value in seconds. The returned time is offset to program start time, so there is enough precision left to deliver microsecond resolution for at least 100 years. Unless it's casted to a float (or the CPU reduces precision), which is why we still use mp_time_us() out of paranoia in places where precision is clearly needed. Always switch to the correct time. The whole point of the new timer calls is that they don't wrap, and storing microseconds in unsigned int variables would negate this. In some cases, remove wrap-around handling for time values.

core: Rewrite some of the A/V sync related code Notable functionality changes: * Timing change between any two frames is now accurately limited to 1/10 of their nominal distance. Previous code did not always use the correct duration. * The status line now keeps showing the same A-V sync value from one video frame change to the next. Previously it kept recalculating the value using a new audio position but the same video position when the status line was updated between video frames. This incorrectly showed the video losing sync with audio. * The status line now displays actual measured A-V difference in autosync mode too. The previous code displayed values that completely ignored real timing in autosync mode, showing 0 A-V difference even when video was significantly behind audio due to inadequate decoding speed. The new behavior can make the shown A-V values appear more unstable if the audio out has unreliable delay measurements (the most likely reason to use autosync), but this is a display change rather than a timing quality change. * Autosync mode now tries to adjust timing by the amount of time vo_flip() calls take, so the calls start earlier and finish at the time the frame should be shown. Previously non-autosync mode adjusted for this but autosync did not. * The warning about the system being too slow to decode the video in realtime is now displayed in autosync mode too.

core: audio: improve audio-only seeks and position reporting Seeking while paused could result in the current audio pts being reported incorrectly due to relevant variables not being reinitialized after the seek until more audio was played. When playing audio-only files, this meant that current overall playback position could be reported incorrectly which in turn could break further seeks. Improve things on two levels: First, store the seek target position and use that as the current playback position for audio-only files until things can be reinitialized. Second, try to reinitialize audio decoding enough to know its current pts even while paused. Also avoid printing the actual huge negative value of MP_NOPTS_VALUE on the status line when pts could not be determined.

player: fix recent speed change regression Commit 5afc025c broke this. The reason is that mpctx->delay is updated when a new video frame is added. This value is also needed to resync audio, but it will be for the wrong PTS. They must be consistent with each other, and if they aren't, initial sync will be off by N video frames, which results at least in worse user experience. This can be reproduced by for example heavily switching between normal and 2x speed, or similar. Fix by readding the video_next_pts field (keeping its use minimal, instead of reverting the commit that removed it).

core: add --keep-open, which doesn't close the file on EOF The --keep-open option causes mpv not to close the current file. Instead, it will pause, and allow the user to seek around. When seeking beyond the end of the file, mpv does a precise seek back to the previous last known position that produced video output. In some corner cases, mpv might not be able to produce video output at all, despite having created a VO. (Possibly when only 1 frame could be decoded, but the video filter chain queues frames. Then a VO would be created, without sending an actual video frame to the VO.) In these cases, the VO window will not redraw, not even OSD. Based on a patch by coax [1].

mplayer: switch back to video PTS for reporting playback time The main problem with video PTS was that it wasn't very useful when playing audio files with cover art. Using the audio time instead was an obvious solution. Unfortunately, this leads to "inexact" reporting of the playback time in paused mode, and audio is always ahead by small, essentially random amounts of time ahead. This is possibly because the times reported by AOs are not entirely accurate when paused (see commit 9b3bf76). Switch back to video PTS, and use a simpler way to deal with the cover art case: if the video has ended, use the audio PTS. Also see commit f9a259e (and the commits referenced from there).

core: add backstep support Allows stepping back one frame via the frame_back_step inout command, bound to "," by default. This uses the precise seeking facility, and a perfect frame index built on the fly. The index is built during playback and precise seeking, and contains (as of this commit) the last 100 displayed or skipped frames. This index is used to find the PTS of the previous frame, which is then used as target for a precise seek. If no PTS is found, the core attempts to do a seek before the current frame, and skip decoded frames until the current frame is reached; this will create a sufficient index and the normal backstep algorithm can be applied. This can be rather slow. The worst case for backstepping is about the same as the worst case for precise seeking if the previous frame can be deduced from the index. If not, the worst case will be twice as slow. There's also some minor danger that the index is incorrect in case framedropping is involved. For framedropping due to --framedrop, this problem is ignored (use of --framedrop is discouraged anyway). For framedropping during precise seeking (done to make it faster), we try to not add frames to the index that are produced when this can happen. I'm not sure how well that works (or if the logic is sane), and it's sure to break with some video filters. In the worst case, backstepping might silently skip frames if you backstep after a user-initiated precise seek. (Precise seeks to do indexing are not affected.) Likewise, video filters that somehow change timing of frames and do not do this in a deterministic way (i.e. if you seek to a position, frames with different timings are produced than when the position is reached during normal playback) will make backstepping silently jump to the wrong frame. Enabling/disabling filters during playback (like for example deinterlacing) will have similar bad effects.

Fix this by sending an idle tick only every 500ms. This is not very proper, but the idea behind the tick event isn't very clean to begin with (and the OSC should use timers instead).

// Timestamp from the last time some timing functions read the
video: display last frame, drain frames on video reconfig Until now, the player didn't care to drain frames on video reconfig. Instead, the VO was reconfigured (i.e. resized) before the queued frames finished displaying. This can for example be observed by passing multiple images with different size as mf:// filename. Then the window would resize one frame before image with the new size is displayed. With --vo=vdpau, the effect is worse, because this VO queues more than 1 frame internally. Fix this by explicitly draining buffered frames before video reconfig. Raise the display time of the last frame. Otherwise, the last frame would be shown for a very short time only. This usually doesn't matter, but helps when playing image files. This is a byproduct of frame draining, because normally, video timing is based on the frames queued to the VO, and we can't do that with frames of different size or format. So we pretend that the frame before the change is the last frame in order to time it. This code is incorrect though: it tries to use the framerate, which often doesn't make sense. But it's good enough to test this code with mf://.

player: handle seek delays differently The code removed from handle_input_and_seek_coalesce() did two things: 1. If there's a queued seek, stop accepting non-seek commands, and delay them to the next playloop iteration. 2. If a seek is executing (i.e. the seek was unqueued, and now it's trying to decode and display the first video frame), stop accepting seek commands (and in fact all commands that were queued after the first seek command). This logic is disabled if seeking started longer than 300ms ago. (To avoid starvation.) I'm not sure why 1. would be needed. It's still possible that a command immediately executed after a seek command sees a "seeking in progress" state, because it affects queued seeks only, and not seeks in progress. Drop this code, since it can easily lead to input starvation, and I'm not aware of any disadvantages. The logic in 2. is good to make seeking behave much better, as it guarantees that the video display is updated frequently. Keep the core idea, but implement it differently. Now this logic is applied to seeks only. Commands after the seek can execute freely, and like with 1., I don't see a reason why they couldn't. However, in some cases, seeks are supposed to be executed instantly, so queue_seek() needs an additional parameter to signal the need for immediate update. One nice thing is that commands like sub_seek automatically profit from the seek delay logic. On the other hand, hitting chapter seek multiple times still does not update the video on chapter boundaries (as it should be). Note that the main goal of this commit is actually simplification of the input processing logic and to allow all commands to be executed immediately.

core: simplify handling of --pause Rename the struct MPOpts "start_pause" field to "pause". Store the user- pause state in that field, so that both runtime pause toggling and the --pause switch change the same variable. Simplify the initialization of pause so that using --pause and changing the file while paused is exactly the same case (changing the file while paused doesn't unpause, this has been always this way). Also make it a bit more consistent. Before, starting with --pause would reset the pause state for every file, instead of following the usual semantics for option switches (compare with behavior of --fs).

core: remove a number of global variables Move them into per-instance structs. This should get rid of all global variables in mplayer.c (not counting those referenced by cfg-mplayer.h). In core/input/ar.c, just remove checking the slave_mode variable. I'm not sure what this code was supposed to achieve, but slave mode is broken, slave mode is actually infeasible on OSX (ar.c is completely OSX specific), and the correct way of doing this would be to disable this input device per command line switch.

core: output --playing-msg message only after at least one frame is shown This way it's possible to retrieve correct information about video, like actual width/height, which in general are available only after at least one frame has been sent to the video output, such as dwidth/dheight. mpv_identify.sh becomes a bit slower, because we let it decode enough audio and video to fill the audio buffers and to send one frame to the video output. Also, --playing-msg isn't shown anymore with --frames=0 (could be fixed by special-casing it, should this break any use cases). Note that in some corner cases, like when the demuxer for some reason returns lots of audio packets but no video packets at the start, but video actually starts later, the --playing-msg will still be output before video starts.

bool paused_for_cache;
player: dynamically change cache wait times Remove the hardcoded wait time of 2 seconds. Instead, adjust the wait time each time we unpause: if downloading the data took longer than its estimated playback time, increase the amount of data we wait for. If it's shorter, decrease it. The +/- is supposed to avoid oscillating between two values if the elapsed time and the wait time are similar. It's not sure if this actually helps with anything, but it can't harm.

double cache_stop_time, cache_wait_time;
core: automatically pause on low cache When the cache fill status goes below a certain threshold, automatically pause the player. When the cache is filled again, unpause again. This is intended to help with streaming from http. It's better to pause a while, rather than exposing extremely crappy behavior when packet reads during decoding block the entire player. In theory, we should try to increase the cache if underruns happen too often. Unfortunately, changing the cache implementation would be very hard, because it's insane code (forks, uses shared memory and "volatile" etc.). So for now, this just reduces the frequency of the stuttering if the network is absolutely too slow to play the stream in realtime.
2012-12-01 23:22:54 +00:00
core: Rewrite some of the A/V sync related code Notable functionality changes: * Timing change between any two frames is now accurately limited to 1/10 of their nominal distance. Previous code did not always use the correct duration. * The status line now keeps showing the same A-V sync value from one video frame change to the next. Previously it kept recalculating the value using a new audio position but the same video position when the status line was updated between video frames. This incorrectly showed the video losing sync with audio. * The status line now displays actual measured A-V difference in autosync mode too. The previous code displayed values that completely ignored real timing in autosync mode, showing 0 A-V difference even when video was significantly behind audio due to inadequate decoding speed. The new behavior can make the shown A-V values appear more unstable if the audio out has unreliable delay measurements (the most likely reason to use autosync), but this is a display change rather than a timing quality change. * Autosync mode now tries to adjust timing by the amount of time vo_flip() calls take, so the calls start earlier and finish at the time the frame should be shown. Previously non-autosync mode adjusted for this but autosync did not. * The warning about the system being too slow to decode the video in realtime is now displayed in autosync mode too.

core: add infrastructure to get screenshots from VOs Add a VO command (VOCTRL_SCREENSHOT) which requests a screenshot directly from the VO. If VO support is available, screenshots will be taken instantly (no more 1 or 2 frames delay). Taking screenshots when hardware decoding is in use will also work (vdpau). Additionally, the screenshots will now use the same colorspace as the video display. Change the central MPContext to be allocated with talloc so that it can be used as a talloc parent context. This commit does not yet implement the functionality for any VO (added in subsequent commits). The old screenshot video filter is not needed anymore if VO support is present, and in that case will not be used even if it is present in the filter chain. If VO support is not available then the filter is used like before. Note that the filter still has some of the old problems, such as delaying the screenshot by at least 1 frame.

Add initial Lua scripting support This is preliminary. There are still tons of issues, and any aspect of scripting may change in the future. I decided to merge this (preliminary) work now because it makes it easier to develop it, not because it's done. lua.rst is clear enough about it (plus some sarcasm). This requires linking to Lua. Lua has no official pkg-config file, but there are distribution specific .pc files, all with different names. Adding a non-pkg-config based configure test was considered, but we'd rather not. One major complication is that libquvi links against Lua too, and if the Lua version is different from mpv's, you will get a crash as soon as libquvi uses Lua. (libquvi by design always runs when a file is opened.) I would consider this the problem of distros and whoever builds mpv, but to make things easier for users, we add a terrible runtime test to the configure script, which probes whether libquvi will crash. This is disabled when cross-compiling, but in that case we hope the user knows what he is doing.

Moreover, it was quite annoying that subsystems had most of the code in a specific file, but the uninit code in loadfile.c (because that's where uninit_player() was implemented). Simplify all this. Remove the flags; e.g. instead of testing for the INITIALIZED_AO flag, test whether mpctx->ao is set. Move uninit code to separate functions, e.g. uninit_audio_out().

config: don't save options to resume-config that didn't change This is approximate: we read each option value on program start (before starting playback of a file), and when writing the resume config, compare each value to the current state. This also means when a value is changed and then changed back, it's not stored. In particular, option values set in config files and on the command line are considered the default. This should help reducing the numbers of options overridden by the resume config. If too much is overridden, it becomes an inconvenience, because changes in config files will apparently have no effect when resuming a file. Also see github issue #574.

demux: add a demuxer thread This adds a thread to the demuxer which reads packets asynchronously. It will do so until a configurable minimum packet queue size is reached. (See options.rst additions.) For now, the thread is disabled by default. There are some corner cases that have to be fixed, such as fixing cache behavior with webradios. Note that most interaction with the demuxer is still blocking, so if e.g. network dies, the player will still freeze. But this change will make it possible to remove most causes for freezing. Most of the new code in demux.c actually consists of weird caches to compensate for thread-safety issues (with the previously single-threaded design), or to avoid blocking by having to wait on the demuxer thread. Most of the changes in the player are due to the fact that we must not access the source stream directly. the demuxer thread already accesses it, and the stream stuff is not thread-safe. For timeline stuff (like ordered chapters), we enable the thread for the current segment only. We also clear its packet queue on seek, so that the remaining (unconsumed) readahead buffer doesn't waste memory. Keep in mind that insane subtitles (such as ASS typesetting muxed into mkv files) will practically disable the readahead, because the total queue size is considered when checking whether the minimum queue size was reached.

build: add option to build a library This library will export the client API functions. Note that this doesn't allow compiling the command line player to link against this library yet. The reason is that there's lots of weird stuff required to setup the execution environment (mostly Windows and OSX specifics), as well as things which are out of scope of the client API and every application has to do on its own. However, since the mpv command line player basically reuses functions from the mpv core to implement these things, it's not very easy to separate the command line player form the mpv core.

void stream_dump(struct MPContext *mpctx);
player: open stream and demuxer asynchronously Run opening the stream and opening the demuxer in a separate thread. This should remove the last code paths in which the player can normally get blocked on network. When the stream is opened, the player will still react to input and so on. Commands to abort opening can also be handled properly, instead of using some of the old hacks in input.c. The only thing the user can really do is aborting loading by navigating the playlist or quitting. Whether playback abort works depends on the stream implementation; with normal network, this will depend on what libavformat (via "interrupt" callback) does. Some pain is caused by DVD/BD/DVB. These want to reload the demuxer sometimes. DVB wants it in order to discard old, inactive streams. DVD/BD for the same reason, and also for reloading stream languages and similar metadata. This means the stream and the demuxer have to be loaded separately. One minor detail is that we now need to copy all global options. This wasn't really needed before, because the options were accessed on opening only, but since opening is now on a separate thread, this obviously becomes a necessity.

// osd.c
command: simplify OSD property display code Probably not many user-visible changes. One notable change is that the terminal OSD code for OSD bar fallback handling is removed with no replacement. Instead, terminal OSD gets the same text message as normal OSD. For volume, this is ok, because the text message is reasonable. Other properties will look worse, but could be adjusted, and there are in fact no other such properties that would be useful in audio-only mode. The fallback message for seeking falls away as well, but that message was useless anyway - the terminal status line provides all information anyway. I believe the show_property_osd() code is now much easier to follow.

core: add backstep support Allows stepping back one frame via the frame_back_step inout command, bound to "," by default. This uses the precise seeking facility, and a perfect frame index built on the fly. The index is built during playback and precise seeking, and contains (as of this commit) the last 100 displayed or skipped frames. This index is used to find the PTS of the previous frame, which is then used as target for a precise seek. If no PTS is found, the core attempts to do a seek before the current frame, and skip decoded frames until the current frame is reached; this will create a sufficient index and the normal backstep algorithm can be applied. This can be rather slow. The worst case for backstepping is about the same as the worst case for precise seeking if the previous frame can be deduced from the index. If not, the worst case will be twice as slow. There's also some minor danger that the index is incorrect in case framedropping is involved. For framedropping due to --framedrop, this problem is ignored (use of --framedrop is discouraged anyway). For framedropping during precise seeking (done to make it faster), we try to not add frames to the index that are produced when this can happen. I'm not sure how well that works (or if the logic is sane), and it's sure to break with some video filters. In the worst case, backstepping might silently skip frames if you backstep after a user-initiated precise seek. (Precise seeks to do indexing are not affected.) Likewise, video filters that somehow change timing of frames and do not do this in a deterministic way (i.e. if you seek to a position, frames with different timings are produced than when the position is reached during normal playback) will make backstepping silently jump to the wrong frame. Enabling/disabling filters during playback (like for example deinterlacing) will have similar bad effects.

core: add struct for queued seek info To prepare for the addition of exact seek support, add a struct for queued seek state and a helper function to update its state.

void queue_seek(struct MPContext *mpctx, enum seek_type type, double amount,
player: handle seek delays differently The code removed from handle_input_and_seek_coalesce() did two things: 1. If there's a queued seek, stop accepting non-seek commands, and delay them to the next playloop iteration. 2. If a seek is executing (i.e. the seek was unqueued, and now it's trying to decode and display the first video frame), stop accepting seek commands (and in fact all commands that were queued after the first seek command). This logic is disabled if seeking started longer than 300ms ago. (To avoid starvation.) I'm not sure why 1. would be needed. It's still possible that a command immediately executed after a seek command sees a "seeking in progress" state, because it affects queued seeks only, and not seeks in progress. Drop this code, since it can easily lead to input starvation, and I'm not aware of any disadvantages. The logic in 2. is good to make seeking behave much better, as it guarantees that the video display is updated frequently. Keep the core idea, but implement it differently. Now this logic is applied to seeks only. Commands after the seek can execute freely, and like with 1., I don't see a reason why they couldn't. However, in some cases, seeks are supposed to be executed instantly, so queue_seek() needs an additional parameter to signal the need for immediate update. One nice thing is that commands like sub_seek automatically profit from the seek delay logic. On the other hand, hitting chapter seek multiple times still does not update the video on chapter boundaries (as it should be). Note that the main goal of this commit is actually simplification of the input processing logic and to allow all commands to be executed immediately.

core: add new support for reading .cue files Playing a .cue file directly will now parse the .cue file, and load and play the file(s) referenced in the cue. If multiple files are referenced, a timeline including all files will be created to create the impression of a single, flat audio file containing all the tracks. For each track, a chapter is created. The chapter navigation commands can be used to jump between tracks. The chapter titles will use the string provided by the track's TITLE cue command. (The -identify command can be used to print all chapters in a not so user friendly way.) Other than the chapter names, there is no attempt at displaying or exposing any other meta data contained in the cue files yet. The handling (or lack of thereof) of gaps (track pregaps and postgaps) is probably not correct yet. In general, mplayer's mapping of tracks to the source audio files can be verified by examining the timeline, which will be printed when passing the -v switch. Note that this has nothing to do with the old cue:// support. The old code isn't touched, and is still only able to play .cue/.bin pairs. Prefixing a .cue file with cue:// will always invoke the old code, while playing a .cue file directly (i.e. "mplayer file.cue") will always use the new code.

In the end, all of these depend on MPContext and store state inside of it, so separate headers aren't all that useful anyway.

player: remove central uninit_player() function and flags mess Each subsystem (or similar thing) had an INITIALIZED_ flag assigned. The main use of this was that you could pass a bitmask of these flags to uninit_player(). Except in some situations where you wanted to uninitialize nearly everything, this wasn't really useful. Moreover, it was quite annoying that subsystems had most of the code in a specific file, but the uninit code in loadfile.c (because that's where uninit_player() was implemented). Simplify all this. Remove the flags; e.g. instead of testing for the INITIALIZED_AO flag, test whether mpctx->ao is set. Move uninit code to separate functions, e.g. uninit_audio_out().
