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.

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.

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.

video: move decoder context from sh_video into new struct This is similar to the sh_audio commit. This is mostly cosmetic in nature, except that it also adds automatical freeing of the decoder driver's state struct (which was in sh_video->context, now in dec_video->priv). Also remove all the stheader.h fields that are not needed anymore.

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.

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.

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.

video: replace d_video->pts field, change PTS jump checks The d_video->pts field was a bit strange. The code overwrote it multiple times (on decoding, on filtering, then once again...), and it wasn't really clear what purpose this field had exactly. Replace it with the mpctx->video_next_pts field, which is relatively unambiguous. Move the decreasing PTS check to dec_video.c. This means it acts on decoder output, not on filter output. (Just like in the previous commit, assume the filter chain is sane.) Drop the jitter vs. reset semantics; the dec_video.c determined PTS never goes backwards, and demuxer timestamps don't "jitter".

audio: don't let ao_lavc access frontend internals, change gapless audio ao_lavc.c accesses ao->buffer, which I consider internal. The access was done in ao_lavc.c/uninit(), which tried to get the left-over audio in order to write the last (possibly partial) audio frame. The play() function didn't accept partial frames, because the AOPLAY_FINAL_CHUNK flag was not correctly set, and handling it otherwise would require an internal FIFO. Fix this by making sure that with gapless audio (used with encoding), the AOPLAY_FINAL_CHUNK is set only once, instead when each file ends. Basically, move the hack in ao_lavc's uninit to uninit_player. One thing can not be entirely correctly handled: if gapless audio is active, we don't know really whether the AO is closed because the file ended playing (i.e. we want to send the buffered remainder of the audio to the AO), or whether the user is quitting the player. (The stop_play flag is overwritten, fixing that is perhaps not worth it.) Handle this by adding additional code to drain the AO and the buffers when playback is quit (see play_current_file() change). Test case: mpv avdevice://lavfi:sine=441 avdevice://lavfi:sine=441 -length 0.2267 -gapless-audio

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: move decoder context from sh_audio into new struct Move all state that basically changes during decoding or is needed in order to manage decoding itself into a new struct (dec_audio). sh_audio (defined in stheader.h) is supposed to be the audio stream header.

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.

The access was done in ao_lavc.c/uninit(), which tried to get the left-over audio in order to write the last (possibly partial) audio frame. The play() function didn't accept partial frames, because the AOPLAY_FINAL_CHUNK flag was not correctly set, and handling it otherwise would require an internal FIFO. Fix this by making sure that with gapless audio (used with encoding), the AOPLAY_FINAL_CHUNK is set only once, instead when each file ends. Basically, move the hack in ao_lavc's uninit to uninit_player. One thing can not be entirely correctly handled: if gapless audio is active, we don't know really whether the AO is closed because the file ended playing (i.e. we want to send the buffered remainder of the audio to the AO), or whether the user is quitting the player. (The stop_play flag is overwritten, fixing that is perhaps not worth it.) Handle this by adding additional code to drain the AO and the buffers when playback is quit (see play_current_file() change).

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.
