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.

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: use the decoder buffer's format, not sh_audio When the decoder detects a format change, it overwrites the values stored in sh_audio (this affects the members sample_format, samplerate, channels). In the case when the old audio data still needs to be played/filtered, the audio format as identified by sh_audio and the format used for the decoder buffer can mismatch. In particular, they will mismatch in the very unlikely but possible case the audio chain is reinitialized while old data is draining during a format change. Or in other words, sh_audio might contain the new format, while the audio chain is still configured to use the old format. Currently, the audio code (player/audio.c and init_audio_filters) access sh_audio to get the current format. This is in theory incorrect for the reasons mentioned above. Use the decoder buffer's format instead, which should be correct at any point.

This actually created a dangling pointer in af_add(), a tricky consequence of af_add() reconfiguring the filter chain and the newly added filter using AF_DETACH. Fortunately the AF_DETACH is not needed (and probably never worked - it comes from MPlayer times, and MPlayer also disables audio when trying to change speed with spdif).

audio: change playback speed directly in resampler Although the libraries we use for resampling (libavresample and libswresample) do not support changing sampelrate on the fly, this makes it easier to make sure no audio buffers are implicitly dropped. In fact, this commit adds additional code to drain the resampler explicitly. Changing speed twice without feeding audio in-between made it crash with libavresample inc ertain cases (libswresample is fine). This is probably a libavresample bug. Hopefully this will be fixed, and also I attempted to workaround the situation that crashes it. (It seems to point in direction of random memory corruption, though.)

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.

In the ordered chapter case, end_pts is used, which means not all audio data in the buffer is played, thus some data is left over when audio decoding resumes on the next segment. This triggers some code that aborts resync if there's "audio decoded" (ao_buffer contains something), but no PTS is known (nothing was actually decoded yet). Simplify, and always bind the output buffer to the decoder. CC: @mpv-player/stable (maybe)

struct mp_audio in_format = mpctx->d_audio->decode_format;
audio: use the decoder buffer's format, not sh_audio When the decoder detects a format change, it overwrites the values stored in sh_audio (this affects the members sample_format, samplerate, channels). In the case when the old audio data still needs to be played/filtered, the audio format as identified by sh_audio and the format used for the decoder buffer can mismatch. In particular, they will mismatch in the very unlikely but possible case the audio chain is reinitialized while old data is draining during a format change. Or in other words, sh_audio might contain the new format, while the audio chain is still configured to use the old format. Currently, the audio code (player/audio.c and init_audio_filters) access sh_audio to get the current format. This is in theory incorrect for the reasons mentioned above. Use the decoder buffer's format instead, which should be correct at any point.

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.

// Weak gapless audio: drain AO on decoder format changes
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().

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.

Remove some of the weird heuristic-heavy code in dec_audio.c. Instead of estimating how much audio we need to filter, we always filter full frames. Maybe this should be adjusted later: in case filtering increases the volume of the audio data, we should try not to buffer too much filter output by reducing the input that is fed at once. For ad_spdif.c and ad_mpg123.c, we don't avoid extra copying yet - it doesn't seem worth the trouble.

player: fix exiting if both audio and video fail initializing The player was supposed to exit playback if both video and audio failed to initialize (or if one of the streams was not selected when the other stream failed). This didn't work; for one this check was missing from one of the failure paths. And more importantly, both checked the current_track array incorrectly. Fix these issues, and move the failure handling code into a common function. CC: @mpv-player/stable

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: make decoders output refcounted frames This rewrites the audio decode loop to some degree. Audio filters don't do refcounted frames yet, so af.c contains a hacky "emulation". Remove some of the weird heuristic-heavy code in dec_audio.c. Instead of estimating how much audio we need to filter, we always filter full frames. Maybe this should be adjusted later: in case filtering increases the volume of the audio data, we should try not to buffer too much filter output by reducing the input that is fed at once. For ad_spdif.c and ad_mpg123.c, we don't avoid extra copying yet - it doesn't seem worth the trouble.

audio: use the decoder buffer's format, not sh_audio When the decoder detects a format change, it overwrites the values stored in sh_audio (this affects the members sample_format, samplerate, channels). In the case when the old audio data still needs to be played/filtered, the audio format as identified by sh_audio and the format used for the decoder buffer can mismatch. In particular, they will mismatch in the very unlikely but possible case the audio chain is reinitialized while old data is draining during a format change. Or in other words, sh_audio might contain the new format, while the audio chain is still configured to use the old format. Currently, the audio code (player/audio.c and init_audio_filters) access sh_audio to get the current format. This is in theory incorrect for the reasons mentioned above. Use the decoder buffer's format instead, which should be correct at any point.

audio: refactor some aspects of filter chain setup There's no real reason why audio_init_filter() should exist. Just use af_init or af_reinit directly. (We lose a useless message; the same information is printed in a quite close place with more details.) Requires less code, and the way the filter chain is marked as having failed to initialize allows just switching off audio instead of crashing if trying to insert a volume filter in mixer.c fails, and recreating the old filter chain fails too.

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.

audio: cut audio with spdif too on playback restart When playback is started after seeking or opening a file, we need to make sure audio and video line up exactly. This is done by cutting or padding the audio stream to start on the video PTS. This does not quite work with spdif: audio is compressed data, within a spdif frame. There is no way to cut the audio "in between" the frames. Cutting between the frames would just produce broken spdif packets, and who knows how receivers will react to this (play noise?). But we still can cut it in frame boundaries. Unfortunately, we also insert 0 data for "silence" - we probably shouldn't do this. Chances are the receiver will switch to PCM or so. But for now this will have to do. Note that this could be simplified somewhat, as soon as we work with frames. See previous commit.

audio: increase maximum amount of audio skipped for seeking Precise seeking requires skipping audio, since the demuxer usually doesn't seek precisely enough. There is a sanity check that prevents skipping more than 300 seconds of audio. This still fails with very large mp3s. For example, with a 1GB sized mp3 with Xing headers, entries will be 4 MB apart on average, and occasionally much more. Just bump the limit. I'm not even sure why it was added in the first place; I suppose it's most important for files with real PTS resets.

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.

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: 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.

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: respect --end/--length with spdif passthrough In theory, we can't really do this, because we don't know when a spdif frame ends. Spdif transports compressed audio through audio setups that were originally designed for PCM only (which includes the audio filter chain, the AO API, most audio output APIs, etc.), and to reach this goal, spdif pretends to be PCM. Compressed data frames are padded with zeros, until a certain data rate is reached, which corresponds to a pseudo-PCM format with 2 bytes per sample and 2 channels at 48000 Hz. Of course an actual spdif frame is significantly larger than a frame of the PCM format it pretends to be, so cutting audio data on frame boundaries (as according to the pseudo-PCM format) merely yields an incomplete and broken frame, not audio that plays for the desired duration. However, sending an incomplete frame might still be much better than the current behavior, which simply ignores --end/--length (but still lets the video end at the exact end time). Should this result in trouble with real spdif receivers, this commit probably has to be reverted.

audio: don't write audio when paused This is probably "safer". Without it, we will play 1 sample, because the logic was written in a way to decode 1 sample if audio is paused. 1 sample usually will initialize the audio PTS, but not play any real audio. Also see previous commit. In ancient times, this actually used 1 byte (instead of 1 sample), so clearly no sample was written, unless the audio was 8-bit mono.

audio: do not exit when loading small files in paused mode When starting in paused mode, no audio is written to the device at all, because writing audio implicitly unpauses the AO. If the file is very small, and all audio fits within the AO buffer, this accidentally triggered the EOF condition. (In unpaused mode, it would write all audio, end playback, and then wait until the AO has everything played.)
