options: add a thread-safe way to notify option updates So far, we had a thread-safe way to read options, but no option update notification mechanism. Everything was funneled though the main thread's central mp_option_change_callback() function. For example, if the panscan options were changed, the function called vo_control() with VOCTRL_SET_PANSCAN to manually notify the VO thread of updates. This worked, but's pretty inconvenient. Most of these problems come from the fact that MPlayer was written as a single-threaded program. This commit works towards a more flexible mechanism. It adds an update callback to m_config_cache (the thing that is already used for thread-safe access of global options). This alone would still be rather inconvenient, at least in context of VOs. Add another mechanism on top of it that uses mp_dispatch_queue, and takes care of some annoying synchronization issues. We extend mp_dispatch_queue itself to make this easier and slightly more efficient. As a first application, use this to reimplement certain VO scaling and renderer options. The update_opts() function translates these to the "old" VOCTRLs, though. An annoyingly subtle issue is that m_config_cache's destructor now releases pending notifications, and must be released before the associated dispatch queue. Otherwise, it could happen that option updates during e.g. VO destruction queue or run stale entries, which is not expected. Rather untested. The singly-linked list code in dispatch.c is probably buggy, and I bet some aspects about synchronization are not entirely sane.

options: support parsing values into substructs Add an alternate mode for option parser objects (struct m_config) which is not inherently tied to any particular instance of an option value struct. Instead, this type or parsers can be used to initialize defaults in or parse values into a struct given as a parameter. They do not have the save slot functionality used for main player configuration. The new functionality will be used to replace the separate subopt_helper.c parsing code that is currently used to parse per-object suboptions in VOs etc. Previously, option default values were handled by initializing them in external code before creating a parser. This initialization was done with constants even for dynamically-allocated types like strings. Because trying to free a pointer to a constant would cause a crash when trying to replace the default with another value, parser initialization code then replaced all the original defaults with dynamically-allocated copies. This replace-with-copy behavior is no longer supported for new-style options; instead the option definition itself may contain a default value (new OPTDEF macros), and the new function m_config_initialize() is used to set all options to their default values. Convert the existing initialized dynamically allocated options in main config (the string options --dumpfile, --term-osd-esc, --input=conf) to use this. Other non-dynamic ones could be later converted to use this style of initialization too. There's currently no public call to free all dynamically allocated options in a given option struct because I intend to use talloc functionality for that (make them children of the struct and free with it).

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.

options: make mess to allow setting profile option with libmpv Certain options, such as --profile, --help, and many others require special-handling, because they don't fit conceptually into the option and property model. They don't store data, but perform actions. This caused the situation that profiles could not be set when using libmpv in encoding mode (although you should probably not used libmpv in encoding mode). Using libmpv always ends up in calling m_config_set_option_raw_direct(), while --profile was handled in m_config_parse_option(). Solve this by moving the handling of this from m_config_parse_option() to m_config_set_option_raw_direct(). Actually we just stuff most of this into m_config_handle_special_options(), which is only called by the aforementioned function. Strangely this also means that the --h/--help option declarations need to be changed, because they used OPT_PRINT, and now the option "parser" is always invoked before the special code. Thus, make them a string. Them being OPT_PRINT was apparently always redundant. (The other option declarations are moved for cosmetic purposes only.) The most weird change is how co->data==NULL is handled. We now allow passing down involved options to m_config_set_option_raw_direct(). The thing is that we don't want them to error if the command line parser is using them (with special handling done there), while all other code paths should raise an error. We try using M_SETOPT_FROM_CMDLINE to distinguish these cases. Note that normal libmpv users are supposed to use the "apply-profile" command instead. This probably contains a bunch of bugs, which you should report.

player: change m_config to use new option handling mechanisms Instead of making m_config a special-case, it more or less uses the underlying m_config_cache/m_config_shadow APIs properly. This makes the player core a (relatively) equivalent user of the core option API. In particular, this means that other threads can change core options with m_config_cache_write_opt() calls (before this commit, this merely led to diverging option values). An important change is that before this commit, mpctx->opts contained the "master copy" of all option data. Now it's just another copy of the option data, and the shadow copy is considered the master. This is why whenever mpctx->opts is written, the change needs to be copied to the master (thus why this commits add a bunch of m_config_notify... calls). If another thread (e.g. a VO) changes an option, async_change_cb is now invoked, which funnels the change notification through the player's layers. The new self_notification parameter on mp_option_change_callback is so that m_config_notify... doesn't trigger recursion, and it's used in cases where the change was already "processed". It's still needed to trigger libmpv property updates. (I considered using an extra m_config_cache for that, but it'd only cause problems with no advantages.) I think the recent changes actually forgot to send libmpv property updates in some cases. This should fix this anyway. In some cases, property updates are reworked, and the potential for bugs should be lower (probably). The primary point of this change is to allow external updates, for example by a VO writing the fullscreen option if the window state is changed by the window manager (rather than mpv changing it). This is not used yet, but the following commits will.

options: make mess to allow setting profile option with libmpv Certain options, such as --profile, --help, and many others require special-handling, because they don't fit conceptually into the option and property model. They don't store data, but perform actions. This caused the situation that profiles could not be set when using libmpv in encoding mode (although you should probably not used libmpv in encoding mode). Using libmpv always ends up in calling m_config_set_option_raw_direct(), while --profile was handled in m_config_parse_option(). Solve this by moving the handling of this from m_config_parse_option() to m_config_set_option_raw_direct(). Actually we just stuff most of this into m_config_handle_special_options(), which is only called by the aforementioned function. Strangely this also means that the --h/--help option declarations need to be changed, because they used OPT_PRINT, and now the option "parser" is always invoked before the special code. Thus, make them a string. Them being OPT_PRINT was apparently always redundant. (The other option declarations are moved for cosmetic purposes only.) The most weird change is how co->data==NULL is handled. We now allow passing down involved options to m_config_set_option_raw_direct(). The thing is that we don't want them to error if the command line parser is using them (with special handling done there), while all other code paths should raise an error. We try using M_SETOPT_FROM_CMDLINE to distinguish these cases. Note that normal libmpv users are supposed to use the "apply-profile" command instead. This probably contains a bunch of bugs, which you should report.
