Split mplayer.c mplayer.c was a bit too big. Split it into multiple files. I hope the way it's split makes sense. Maybe some things don't make too much sense, or go against intuition. These will fixed as soon as I notice them. Some files are a bit questionable (misc.c, osd.c, configfiles.c), and suggestions how to organize this better are welcome. Regressions are possible due to reorganized include statements. Obviously I didn't just copy mplayer.c's orgy of include statements, but recreated them for each file. It's easily possible that there are oversights and mistakes, which will show up on other platforms. There is one actual change: the public avutil.h include is removed from encode.h, and I tried to replace most FFMIN/FFMAX/av_clip uses. I consider using libavutil too much as dangerous, because the set of include files they recursively pull in is rather arbitrary and is different between FFmpeg and Libav.

player: change license of most core files to LGPL These files have all in common that they were fully or mostly taken from mplayer.c. (mplayer.c was a huge file that contains almost all of the playback core, until it was split into multiple parts.) This was probably the hardest part to relicense, because so much code was moved around all the time. player/audio.c still does not compile. We'll have to redo audio filtering. Once that is done, we can probably actually provide an actual LGPL configure switch. Here is a relatively detailed list of potential issues: 8d190244: author did not reply, parts were made GPL-only in a previous commit. 7882ea9b: author could not be reached, but the code is gone. wscript still has --datadir switch, but I don't think this is relevant to copyright. f197efd5: unclear origin, but I consider the code gone anyway (replaced with generic OSD mechanisms). 8337d9c2: author did not reply, but only the option still exists (under a different name), other code was removed. d8fd7131: did not reply. Disabled in a previous commit. 05258251: same author as above. Both fields actually seem to have vanished (even when tracking renames), so no action taken. d459e644, 268b2c1a: author did not reply, but we reuse only the options (with different names and slightly or fully different semantics, and completely different implementations), so I don't think this is relevant for copyright. 09e742fe, 17c39c4e: same as above. e8a173de, bff4b3ee: author could not be reached. The commands were reworked to properties, and the code outside of the TV code were moved back to the TV code. So I don't think copyright applies to the current command.c parts (mp_property_tv_color, mp_property_tv_freq, mp_property_tv_scan). The TV parts remain GPL. 0810e427: could not be reached. Disabled in a previous commit. 43744a2d: unknown author, but this was replaced by dynamic alloc (if the change is even copyrightable). 116ca0c7: unknown author; reasoning see input.c relicensing commit. e7e4d1d8: these semantics still exist, but as generic code, and this code was fully removed. f1175cd9: the author of the cited patch is unknown, and upon inspection it turns out that I was only using the idea to pause the player on EOF, so I claim it's not copyright relevant. 25affdcc: author could not be reached (yet) - but it's only a function rename, not copyrightable. 5728504c was committed by Arpi (who agreed), but hints that it might be by a different author. In fact it seems to be mostly this patch: http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2001-November/002041.html The author did not respond, but it all seems to have been removed later. It's a terrible mess though. Arpi reverted the A-V sync code at first, but left the RTC code for a while. The following commits remove these changes 100%: 14b35442, 7181a091, 31482783, 614f8475, df58e822. cehoyos did explicitly not agree to LGPL, but was involved in the following changes: c99d8fc8: applied a patch and didn't modify it, the original author agreed. 40ac0d31: author could not be reached, but all code is gone anyway. The "af" command has a similar function, but works completely different and actually reuses a mechanism older than this patch. 54350436: applied a patch, but didn't modify it, except for adding a German translation, which was removed later. a2dda036: same situation as above 240b743e: this was made GPL-only in a previous commit 7b25afd7: same as above (for now) kirijua could not be reached, but was a regular patch contributor: c2c997fd: video equalizer code move; probably not copyrightable. Is GPL due to Nick anyway. be54f481: technically, this became the audio track property later. But all what is left is the fact that you pass a track ID to it, so consider the original coypright non-relevant. 2f376d1b: this was rewritten in b7052b43, but for now we can afford to be careful, so this was marked as GPL only in a previous commit. 43844d09: remaining parts in main.c were reverted in a previous commit. anders has mostly disagreed with the LGPL relicensing. Does not want libaf to become LGPL, but made some concessions. In particular, he granted us permission to relicense 4943e9c52c and 242aa6ebd4. We also consider some of his changes remaining in mpv not relevant for copyright (such as 735de602 - we won't remove the this option completely). We will completely remove his other contributions, including the entire audio filter chain. For now, this stuff is marked as GPL only. The remaining question is how much code in player/audio.c (based on the former mplayer.c and dec_audio.c) is under his copyright. I made claims about this in a previous commit. Nick(ols) Kurshev, svn username "nick" and "nickols_k", could not be reached. He had a lot of changes in early MPlayer. It seems all of that was removed, at least in mpv. His main work, like VIDIX or libswscale work, does not exist in mpv anymore, but the changes to mplayer.c and other core parts still deserve attention: a4119f6b, fb927549, ad3529b8, e11b23dc, 5f2178be, 93c371d5: removed in b43d67e0, d1628d12, 24ed01fe, df58e822. 0a83c6ec, 104c125e, 4e067f62, aec5dcc8, b587a3d6, f3de6e6b: DR, VAA, and "tune" stuff was fully removed later on or replaced with other mechanisms. 340183b0: screenshots were redone later (the VOCTRL was even removed, with an independent implementation using the same VOCTRL a few years later), so not relevant anymore. Basically only the 's' shortcut remains (but not its implementation). 92c5c274, bffd4007, 555c6766: for now marked as GPL only in a previous commit. Might contain some trace amounts of "michael"'s copyright, who agreed to LGPL only once the core is relicensed. This will still be respected, but I don't think it matters at this in this case. (Some code touched by him was merged into mplayer.c, and then disappeared after heavy refactoring.) I tried to be as careful and as complete as possible. It can't be excluded that amends to this will be made later. This does not make the player LGPL yet.

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.

encode: don't access ao->pts This field will be moved out of the ao struct. The encoding code was basically using an invalid way of accessing this field. Since the AO will be moved into its own thread too and will do its own buffering, the AO and the playback core might not even agree which sample a PTS timestamp belongs to. Add some extrapolation code to handle this case.

audio: make libaf derived code optional This code could not be relicensed. The intention was to write new filter code (which could handle both audio and video), but that's a bit of work. Write some code that can do audio conversion (resampling, downmixing, etc.) without the old audio filter chain code in order to speed up the LGPL relicensing. If you build with --disable-libaf, nothing in audio/filter/* is compiled in. It breaks a few features, such as --volume, --af, pitch correction on speed changes, replaygain. Most likely this adds some bugs, even if --disable-libaf is not used. (How the fuck does EOF notification work again anyway?)

audio: refactor how data is passed to AO This replaces the two buffers (ao_chain.ao_buffer in the core, and buffer_state.buffers in the AO) with a single queue. Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

audio: move to decoder wrapper Use the decoder wrapper that was introduced for video. This removes all code duplication the old audio decoder wrapper had with the video code. (The audio wrapper was copy pasted from the video one over a decade ago, and has been kept in sync ever since by the power of copy&paste. Since the original copy&paste was possibly done by someone who did not answer to the LGPL relicensing, this should also remove all doubts about whether any of this code is left, since we now completely remove any code that could possibly have been based on it.) There is some complication with spdif handling, and a minor behavior change (it will restrict the list of codecs to spdif if spdif is to be used), but there should not be any difference in practice.

The important part is that it works much like the resample or scaletempo filters. For PCM audio, this does not work on samples anymore. This makes it much worse.

Separate the speed change into a light-weight function, which merely updates already created filters, and a heavy-weight one which messes with filter insertion. This also happens to fix the case where the filters would "forget" the current speed (force resampling, change speed, hit a volume control to force af_volume insertion - it will reset speed and desync). Since we now always run the light-weight function, remove the af_scaletempo verbose message that is printed on speed setting. Other than that, all setters are cheap.

(The audio wrapper was copy pasted from the video one over a decade ago, and has been kept in sync ever since by the power of copy&paste. Since the original copy&paste was possibly done by someone who did not answer to the LGPL relicensing, this should also remove all doubts about whether any of this code is left, since we now completely remove any code that could possibly have been based on it.) There is some complication with spdif handling, and a minor behavior change (it will restrict the list of codecs to spdif if spdif is to be used), but there should not be any difference in practice.

ao_c->out_eof = false;
player: partially rework --cache-pause The --cache-pause feature (enabled by default) will pause playback for a while if network runs out of data. If this is not done, then playback will go on frame-wise (as packets are slowly read from the network and then instantly decoded and displayed). This feature is actually useless, as you won't get nice playback no matter what if network is too slow, but I guess I still prefer this behavior for some reason. This commit changes this behavior from using the demuxer cache state only, to trying to use underrun information from the AO/VO. This means if you have a very large audio buffer, then cache-pausing will trigger once that buffer is depleted, which will be some time _after_ the demuxer cache has run out. This requires explicit support from the AO. Otherwise, the behavior should be mostly the same as before this commit. This does not care about the AO buffer. In theory, the AO may underrun, then the player will write some data to the AO buffer, then the AO will recover and play this bit of data, then the player will probably trigger the cache-pause behavior. The probability of this happening should be pretty low, so I will hold off fixing this until the next refactor of the AO chain (if ever). The VO underflow detection was devised and tested in 5 minutes, and may not be correct. At least I'm fairly sure that the combination of all the factors should make incorrect behavior relatively unlikely, but problems are possible. Also, the demux_reader_state.underrun field may be inaccurate. It's only the present state at the time demux_get_reader_state() was called, and may exclude past underruns. In theory, this could cause "close" cases to be missed. Then you might get an audio underrun without cache-pausing acting on it. If the stars align, this could happen multiple times in the row, effectively making this feature not work. The most user-visible consequence of this change is that the user will now see an AO underrun warning every time the cache runs out. Maybe this cache-pause feature should just be removed...

audio: refactor how data is passed to AO This replaces the two buffers (ao_chain.ao_buffer in the core, and buffer_state.buffers in the AO) with a single queue. Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

f_decoder_wrapper: replace most public fields with setters/getters I may (optionally) move decoding to a separate thread in a future change. It's a bit attractive to move the entire decoder wrapper to there, so if the demuxer has a new packet, it doesn't have to wake up the main thread, and can directly wake up the decoder. (Although that's bullshit, since there's a queue in between, and libavcodec's multi-threaded decoding plays cross-threads ping pong with packets anyway. On the other hand, the main thread would still have to shuffle the packets around, so whatever, just seems like better design.) As preparation, there shouldn't be any mutable state exposed by the wrapper. But there's still a large number of corner-caseish crap, so just use setters/getters for them. This recorder thing will inherently not work, so it'll have to be disabled if threads are used. This is a bit painful, but probably still the right thing. Like speculatively pulling teeth.

audio: refactor: work towards unentangling audio decoding and filtering Similar to the video path. dec_audio.c now handles decoding only. It also looks very similar to dec_video.c, and actually contains some of the rewritten code from it. (A further goal might be unifying the decoders, I guess.) High potential for regressions.

audio: reduce excessive logging of delayed audio start Since this is a messy and fragile mechanism, I want it logged (even if it's somewhat in conflict with the verbose logging policy). On the other hand, it's unconditionally logged on every playloop iteration. So add some nonsense to log it only on progress.

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().

audio: refactor how data is passed to AO This replaces the two buffers (ao_chain.ao_buffer in the core, and buffer_state.buffers in the AO) with a single queue. Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

So what we do is we just use AVFrame (which of course is LGPL with 100% certainty), and add some accessors around it to adapt it to mpv conventions. Also, this gets rid of some annoying conventions of mp_audio, like the struct fields that require using an accessor to write to them anyway. For the most part, this change is only dumb replacements of mp_audio related functions and fields. One minor actual change is that you can't allocate the new type on the stack anymore.

audio: don't recreate AO if a filter changes the output format Until recently, the AO was reinitialized strictly only on decoder format changes. But the commit for simplifying audio format negotiation removed this. Now the AO is recreated for any format change. This is sort of annoying if you change playback speed. The insertion/removal of af_scaletempo can change the sample format. For example, the acompressor filter will convert output to double, so toggling scaletempo will force the format back to float. This recreates the AO under the --gapless-audio=weak default. This likely affects a lot of other filters too. Work this around by allowing sample format changes, and keeping the current AO format in these cases. This is probably not a big problem. Most audio APIs force the output format to float anyway. This means you actually have to worry about what the default gapless mode does to your audio. If you start with a file that uses 8 bit per sample, and then continue playing a 24 bit FLAC, it will be converted down to 8 bit per sample. (Assuming they are played in a way that uses the gapless logic.)

Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

audio: fix replaygain being completely broken Switching to a new file while keeping the AO didn't update the volume. While there's an explicit audio_update_volume() call in reinit_audio_chain_src(), it doesn't work, because at that point ao_chain->ao is still NULL, and it does nothing. That's pretty weird and might cause other problems (what happens if you try to mute while the AO is "floating"?). Regarding gapless, trying to use the AO gain for replaygain is also gross nonsense, because the new replaygain computed gain would affect audio from the previous file. It looks like replaygain should be in an af_volume filter maybe. On the other hand, I enjoy setting ridiculous replaygain-preamp values and compensating with a low volume setting, which would not work well if both gains were applied to the audio independently. For now, just add the missing call. This is orthogonal to fixing replaygain "properly".

Split mplayer.c mplayer.c was a bit too big. Split it into multiple files. I hope the way it's split makes sense. Maybe some things don't make too much sense, or go against intuition. These will fixed as soon as I notice them. Some files are a bit questionable (misc.c, osd.c, configfiles.c), and suggestions how to organize this better are welcome. Regressions are possible due to reorganized include statements. Obviously I didn't just copy mplayer.c's orgy of include statements, but recreated them for each file. It's easily possible that there are oversights and mistakes, which will show up on other platforms. There is one actual change: the public avutil.h include is removed from encode.h, and I tried to replace most FFMIN/FFMAX/av_clip uses. I consider using libavutil too much as dangerous, because the set of include files they recursively pull in is rather arbitrary and is different between FFmpeg and Libav.

For the second purpose, it could be called multiple times (even though it wasn't really idempotent). This was pretty weird, so make them separate functions. The new function is actually idempotent too. It also turns out the reinit functions don't have to call themselves recursively for the spdif PCM fallback.

audio: add a "weak" gapless mode, and make it default Basically, this allows gapless playback with similar files (including the ordered chapter case), while still being robust in general. The implementation is quite simplistic on purpose, in order to avoid all the weird corner cases that can occur when creating the filter chain. 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. Just using "--gapless-audio" or "--gapless-audio=yes" selects the old mode.

audio: don't recreate AO if a filter changes the output format Until recently, the AO was reinitialized strictly only on decoder format changes. But the commit for simplifying audio format negotiation removed this. Now the AO is recreated for any format change. This is sort of annoying if you change playback speed. The insertion/removal of af_scaletempo can change the sample format. For example, the acompressor filter will convert output to double, so toggling scaletempo will force the format back to float. This recreates the AO under the --gapless-audio=weak default. This likely affects a lot of other filters too. Work this around by allowing sample format changes, and keeping the current AO format in these cases. This is probably not a big problem. Most audio APIs force the output format to float anyway. This means you actually have to worry about what the default gapless mode does to your audio. If you start with a file that uses 8 bit per sample, and then continue playing a 24 bit FLAC, it will be converted down to 8 bit per sample. (Assuming they are played in a way that uses the gapless logic.)

In addition to the things mentioned above, the --audio-channels option is extended to accept a set of channel layouts.

This is supposed to be the correct way to configure mpv ALSA multichannel output. You need to put a list of channel layouts that your A/V receiver supports.

(I don't care enough to prevent this.) (This is named after the old S/PDIF connector, because it uses the same underlying technology as far as the higher level protoco is concerned. Also, the user should be renamed that passthrough is backwards.)

It's easily possible that there are oversights and mistakes, which will show up on other platforms. There is one actual change: the public avutil.h include is removed from encode.h, and I tried to replace most FFMIN/FFMAX/av_clip uses. I consider using libavutil too much as dangerous, because the set of include files they recursively pull in is rather arbitrary and is different between FFmpeg and Libav.

(Although that's bullshit, since there's a queue in between, and libavcodec's multi-threaded decoding plays cross-threads ping pong with packets anyway. On the other hand, the main thread would still have to shuffle the packets around, so whatever, just seems like better design.) As preparation, there shouldn't be any mutable state exposed by the wrapper. But there's still a large number of corner-caseish crap, so just use setters/getters for them. This recorder thing will inherently not work, so it'll have to be disabled if threads are used. This is a bit painful, but probably still the right thing. Like speculatively pulling teeth.

audio: make libaf derived code optional This code could not be relicensed. The intention was to write new filter code (which could handle both audio and video), but that's a bit of work. Write some code that can do audio conversion (resampling, downmixing, etc.) without the old audio filter chain code in order to speed up the LGPL relicensing. If you build with --disable-libaf, nothing in audio/filter/* is compiled in. It breaks a few features, such as --volume, --af, pitch correction on speed changes, replaygain. Most likely this adds some bugs, even if --disable-libaf is not used. (How the fuck does EOF notification work again anyway?)

audio: add a "weak" gapless mode, and make it default Basically, this allows gapless playback with similar files (including the ordered chapter case), while still being robust in general. The implementation is quite simplistic on purpose, in order to avoid all the weird corner cases that can occur when creating the filter chain. 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. Just using "--gapless-audio" or "--gapless-audio=yes" selects the old mode.

audio: refactor how data is passed to AO This replaces the two buffers (ao_chain.ao_buffer in the core, and buffer_state.buffers in the AO) with a single queue. Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

audio: prevent uninit_audio_out during encoding There was a simple oversight that meant audio outputs were uninitialized during an encoding, which is not allowed, the encoding would stop with numerous errors. I added a single line to prevent the call of uninit_audio_out in reinit_audio_chain if the encoder was active and this appears to have fixed the problem without breaking anything else. Fixes #8568

audio: refactor how data is passed to AO This replaces the two buffers (ao_chain.ao_buffer in the core, and buffer_state.buffers in the AO) with a single queue. Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

It was needed in the ever ongoing transition from something to... something else. A good example for the need of this bridge is applying profiles at runtime. This obviously goes through the config parser, but should also make all changes effective, for which traditionally the property layer is used. There isn't much left that needs this bridge. This commit changes a bunch of options (which also have a property implementation) to use option change notifications instead. Many of the properties are still left, but perform unrelated functions like OSD formatting. This should be mostly compatible. There may be some subtle behavior changes. For example, "hwdec" and "record-file" do not check for changes anymore before applying them, so writing the current value to them suddenly does something, while it was ignored before. DVB changes untested, but should work.

Revert "audio: set audio chain ao on reinit" This reverts commit 3239e41277173bace5ecc2a22910c4660642429c. I'm fairly sure this is wrong, and my next commit should fix it properly. I'm not really sure, though. Normally, the AO is set again by reinit_audio_filters_and_output() after the new audio chain has decoded a frame and knows the new format. The reason replaygain (and apparently the thing the reverted commit tried to fix) didn't work is because they work asynchronously to the audio played by the AO (i.e. buggy and hard to fix).

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.

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.

Further, we use this separation to make sure only a resampler is inserted if playback speed is only changed for video sync correction. As of this commit, this is basically inactive code. It's just preparation for the video sync code (the following commit).

Split mplayer.c mplayer.c was a bit too big. Split it into multiple files. I hope the way it's split makes sense. Maybe some things don't make too much sense, or go against intuition. These will fixed as soon as I notice them. Some files are a bit questionable (misc.c, osd.c, configfiles.c), and suggestions how to organize this better are welcome. Regressions are possible due to reorganized include statements. Obviously I didn't just copy mplayer.c's orgy of include statements, but recreated them for each file. It's easily possible that there are oversights and mistakes, which will show up on other platforms. There is one actual change: the public avutil.h include is removed from encode.h, and I tried to replace most FFMIN/FFMAX/av_clip uses. I consider using libavutil too much as dangerous, because the set of include files they recursively pull in is rather arbitrary and is different between FFmpeg and Libav.

audio: refactor how data is passed to AO This replaces the two buffers (ao_chain.ao_buffer in the core, and buffer_state.buffers in the AO) with a single queue. Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

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.

Write some code that can do audio conversion (resampling, downmixing, etc.) without the old audio filter chain code in order to speed up the LGPL relicensing. If you build with --disable-libaf, nothing in audio/filter/* is compiled in. It breaks a few features, such as --volume, --af, pitch correction on speed changes, replaygain. Most likely this adds some bugs, even if --disable-libaf is not used. (How the fuck does EOF notification work again anyway?)

audio: refactor how data is passed to AO This replaces the two buffers (ao_chain.ao_buffer in the core, and buffer_state.buffers in the AO) with a single queue. Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

audio: improve aspects of EOF handling The code actually kept going out of EOF mode into resync mode back into EOF mode when the playloop had to wait after an audio EOF caused by the endpts.

The idiotic ao_buffer makes this an amazing pain in the ass.

f_decoder_wrapper: replace most public fields with setters/getters I may (optionally) move decoding to a separate thread in a future change. It's a bit attractive to move the entire decoder wrapper to there, so if the demuxer has a new packet, it doesn't have to wake up the main thread, and can directly wake up the decoder. (Although that's bullshit, since there's a queue in between, and libavcodec's multi-threaded decoding plays cross-threads ping pong with packets anyway. On the other hand, the main thread would still have to shuffle the packets around, so whatever, just seems like better design.) As preparation, there shouldn't be any mutable state exposed by the wrapper. But there's still a large number of corner-caseish crap, so just use setters/getters for them. This recorder thing will inherently not work, so it'll have to be disabled if threads are used. This is a bit painful, but probably still the right thing. Like speculatively pulling teeth.

But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

void fill_audio_out_buffers(struct MPContext *mpctx)
Split mplayer.c mplayer.c was a bit too big. Split it into multiple files. I hope the way it's split makes sense. Maybe some things don't make too much sense, or go against intuition. These will fixed as soon as I notice them. Some files are a bit questionable (misc.c, osd.c, configfiles.c), and suggestions how to organize this better are welcome. Regressions are possible due to reorganized include statements. Obviously I didn't just copy mplayer.c's orgy of include statements, but recreated them for each file. It's easily possible that there are oversights and mistakes, which will show up on other platforms. There is one actual change: the public avutil.h include is removed from encode.h, and I tried to replace most FFMIN/FFMAX/av_clip uses. I consider using libavutil too much as dangerous, because the set of include files they recursively pull in is rather arbitrary and is different between FFmpeg and Libav.

audio/out: make ao_request_reload() idempotent This is what you would expect. Before this commit, each ao_request_reload() call would just queue a reload command, and then recreate the AO for the number of times the function was called. Instead of sending a command, introduce some sort of event retrieval mechanism. At least for the reload case, use atomics, because we're too lazy to setup an extra mutex.

encode: get rid of the output packet queue Until recently, ao_lavc and vo_lavc started encoding whenever the core happened to send them data. Since audio and video are not initialized at the same time, and the muxer was not necessarily opened when the first encoder started to produce data, the resulting packets were put into a queue. As soon as the muxer was opened, the queue was flushed. Change this to make the core wait with sending data until all encoders are initialized. This has the advantage that we don't need to queue up the packets.

It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic.

There are no functional changes, except handling "new_frame_shown" slightly differently. This is done so that we don't need new a new MPContext field or a return value for write_video() to signal this condition. Instead, it's handled indirectly.

Write some code that can do audio conversion (resampling, downmixing, etc.) without the old audio filter chain code in order to speed up the LGPL relicensing. If you build with --disable-libaf, nothing in audio/filter/* is compiled in. It breaks a few features, such as --volume, --af, pitch correction on speed changes, replaygain. Most likely this adds some bugs, even if --disable-libaf is not used. (How the fuck does EOF notification work again anyway?)

audio: move back PTS jump detection to before filter chain The recent changes to player/audio.c moved PTS jump detection to after audio filtering. This was mostly done for convenience, because dataflow between decoder and filters was made "automatic", and jump detection would have to be done as filter. Now move it back to after decoders, again out of convenience. The future direction is to make the dataflow between filters and AO automatic, so this is a bit in the way. Another reason is that speed changes tend to cause jumps - these are legitimate, but get annoying quickly.

f_decoder_wrapper: replace most public fields with setters/getters I may (optionally) move decoding to a separate thread in a future change. It's a bit attractive to move the entire decoder wrapper to there, so if the demuxer has a new packet, it doesn't have to wake up the main thread, and can directly wake up the decoder. (Although that's bullshit, since there's a queue in between, and libavcodec's multi-threaded decoding plays cross-threads ping pong with packets anyway. On the other hand, the main thread would still have to shuffle the packets around, so whatever, just seems like better design.) As preparation, there shouldn't be any mutable state exposed by the wrapper. But there's still a large number of corner-caseish crap, so just use setters/getters for them. This recorder thing will inherently not work, so it'll have to be disabled if threads are used. This is a bit painful, but probably still the right thing. Like speculatively pulling teeth.

player: detect audio PTS jumps, make video PTS heuristic less aggressive This is another attempt at making files with sparse video frames work better. The problem is that you generally can't know whether a jump in video timestamps is just a (very) long video frame, or a timestamp reset. Due to the existence of files with sparse video frames (new frame only every few seconds or longer), every heuristic will be arbitrary (in general, at least). But we can use the fact that if video is continuous, audio should also be continuous. Audio discontinuities can be easily detected, and if that happens, reset some of the playback state. The way the playback state is reset is rather radical (resets decoders as well), but it's just better not to cause too much obscure stuff to happen here. If the A/V sync code were to be rewritten, it should probably strictly use PTS values (not this strange time_frame/delay stuff), which would make it much easier to detect such situations and to react to them.

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.

Instead of having a byte based buffer, the queue is simply a list of audio frames, as output by the decoder. This should make dataflow simpler and reduce copying. It also attempts to simplify fill_audio_out_buffers(), the function I always hated most, because it's full of subtle and buggy logic. Unfortunately, I got assaulted by corner cases, dumb features (attempt at seamless looping, really?), and other crap, so it got pretty complicated again. fill_audio_out_buffers() is still full of subtle and buggy logic. Maybe it got worse. On the other hand, maybe there really is some progress. Who knows. Originally, the data flow parts was meant to be in f_output_chain, but due to tricky interactions with the playloop code, it's now in the dummy filter in audio.c. At least this improves the way the audio PTS is passed to the encoder in encoding mode. Now it attempts to pass frames directly, along with the pts, which should minimize timestamp problems. But to be honest, encoder mode is one big kludge that shouldn't exist in this way. This commit should be considered pre-alpha code. There are lots of bugs still hiding.

player: really start audio only once video is ready The check whether video is ready yet was done only in STATUS_FILLING. But it also switched to STATUS_READY, which means the next time fill_audio_out_buffers() was called, audio would actually be started before video. In most situations, this bug didn't show up, because it was only triggered if the demuxer didn't provide video packets quickly enough, but did for audio packets. Also log when audio is started. (I hate fill_audio_out_buffers(), why did I write it?)

Split mplayer.c mplayer.c was a bit too big. Split it into multiple files. I hope the way it's split makes sense. Maybe some things don't make too much sense, or go against intuition. These will fixed as soon as I notice them. Some files are a bit questionable (misc.c, osd.c, configfiles.c), and suggestions how to organize this better are welcome. Regressions are possible due to reorganized include statements. Obviously I didn't just copy mplayer.c's orgy of include statements, but recreated them for each file. It's easily possible that there are oversights and mistakes, which will show up on other platforms. There is one actual change: the public avutil.h include is removed from encode.h, and I tried to replace most FFMIN/FFMAX/av_clip uses. I consider using libavutil too much as dangerous, because the set of include files they recursively pull in is rather arbitrary and is different between FFmpeg and Libav.

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.
