* video: create a separate context for video filter chainwm42013-12-071-1/+2
| | | | | | This adds vf_chain, which unlike vf_instance refers to the filter chain as a whole. This makes the filter API less awkward, and will allow handling format negotiation better.
* player: always reset some variables on seekwm42013-11-291-4/+4
| | | | | | These were confined to the video path, but resetting them even if no video is available shouldn't really matter. Always resetting them makes the logic easier to follow, I think.
* player: simple hack to make backstep code somewhat more robustwm42013-11-281-3/+12
| | | | | | | | | | | | | | | | | | | The hr-seek code assumes that when seeking the demuxer, the first image decoded after the seek will have a PTS exactly equal to the demuxer seek target time, or before that target time. Incorrect timestamps, implicitly dropped initial frames, or broken files/demuxers can all break this assumption, and lead to hr-seek missing the seek target. Generally, this is not much a problem (the user won't notice being off by one frame), but it really shows when using the backstep feature. In this case, backstepping would simply hang. Add a simple hack that basically forces a minimal value for the --hr- seek-demuxer-offset option (which is 0 by default) when doing a backstep-seek. The chosen minimum value is arbitrary. There's no perfect value, though in general it should perhaps be slightly longer than the frametime, which the chosen value is more than enough for typical framerates.
* video: replace d_video->pts field, change PTS jump checkswm42013-11-271-3/+4
| | | | | | | | | | | | | 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".
* Move some code from player to audio/video reset functionswm42013-11-271-9/+0
|
* cosmetics: rename video/audio reset functionswm42013-11-271-2/+2
| | | | | | | | | | These used the suffix _resync_stream, which is a bit misleading. Nothing gets "resynchronized", they really just reset state. (Some audio decoders actually used to "resync" by reading packets for resuming playback, but that's not the case anymore.) Also move the function in dec_video.c to the top of the file.
* video: unbreak --no-correct-pts with demuxers that use DTSwm42013-11-261-1/+1
|
* player: only pause for waiting on cache if it makes sensewm42013-11-251-1/+3
| | | | | | | | | If the value for --cache-on-pause is larger than --cache-min, and the cache runs below --cache-on-pause, but above --cache-min, the logic would demand to pause the player and then unpause immediately again. This doesn't make much sense, and alternating the pause state in each playloop iteration has negative consequences. Add an explicit check to avoid this situation.
* player: merge no-correct-pts with correct-pts codewm42013-11-251-0/+1
| | | | | | Now the --no-correct-pts mode is like the normal mode, just with different timestamp calculations. The semantics should be about the same as before this commit.
* Rename sub.c/.h to osd.c/.hwm42013-11-241-1/+1
| | | | | This was way too misleading. osd.c merely calls the subtitle renderers, instead of actually dealing with subtitles.
* video: move decoder context from sh_video into new structwm42013-11-231-20/+19
| | | | | | | | | | 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: move decoder context from sh_audio into new structwm42013-11-231-18/+18
| | | | | | | | | 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. This should reflect the file headers for the stream. Putting the decoder context there is strange design, to say the least.
* audio: drop buffered filter data when seekingwm42013-11-181-0/+2
| | | | | This could lead to (barely) audible artifacts with --af=scaletempo and modified playback speed.
* player: simplify audio reset when seekingwm42013-11-181-15/+10
| | | | | | | | | | Some decoders used to read packets and decode data when calling resync_audio_stream(). This required a special case in mp_seek() for audio. (A comment mentions liba52, which is long gone; but until recently ad_mpg123.c actually exposed this behavior.) No decoder does this anymore, and resync_audio_stream() works similar as resync_video_stream(). Remove the special case.
* demux: simplify handling of filepos fieldwm42013-11-161-1/+1
| | | | | | | | | | | | demuxer->filepos contains the byte offset of the last read packet. This is so that the player can estimate the current playback position, if no proper timestamps are available. Simplify it to use demux_packet->pos in the generic demuxer code, instead of bothering every demuxer implementation about it. (Note that this is still a bit incorrect: it relfects the position of the last packet read by the demuxer, not that returned to the user. But that was already broken, and is not that trivial to fix.)
* player: factor audio buffer clearing codewm42013-11-081-7/+4
| | | | | | | Note that the change in seek_reset is not entirely equivalent: we even drop the remainder of buffered audio when seeking. This should be more correct, because the whole point of the reset_ao parameter is to control whether audio queued for output should be dropped or not.
* audio: don't let ao_lavc access frontend internals, change gapless audiowm42013-11-081-1/+3
| | | | | | | | | | | | | | | | | | | | | | | 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

| * demux: make determining seek capability genericwm42013-11-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of having each demuxer do it (only demux_mkv actually did...), let generic code determine whether the file is seekable. This requires adding exceptions to demuxers where the stream is not seekable, but the demuxer is. Sort-of try to improve handling of unseekable files in the player. Exit early if the file is determined to be unseekable, instead of resetting all decoders and then performing a pointless seek. Add an exception to allow seeking if the file is not seekable, but the stream cache is enabled. Print a warning in this case, because seeking outside the cache (which we can't prevent since the demuxer is not aware of this problem) still messes everything up.
| * demux: remove movi_start/movi_end fieldswm42013-11-031-2/+3
| | | | | | | | | | | | | | Pointless, using stream->start_pos/end_pos instead. demux_mf was the only place where this was used specially, but we can rely on timestamps instead for this case.
* | configure: uniform the defines to #define HAVE_xxx (0|1)Stefano Pigozzi2013-11-031-2/+2
|/ | | | | | | | | | | | | | | | | | | | | The configure followed 5 different convetions of defines because the next guy always wanted to introduce a new better way to uniform it[1]. For an hypothetic feature 'hurr' you could have had: * #define HAVE_HURR 1 / #undef HAVE_DURR * #define HAVE_HURR / #undef HAVE_DURR * #define CONFIG_HURR 1 / #undef CONFIG_DURR * #define HAVE_HURR 1 / #define HAVE_DURR 0 * #define CONFIG_HURR 1 / #define CONFIG_DURR 0 All is now uniform and uses: * #define HAVE_HURR 1 * #define HAVE_DURR 0 We like definining to 0 as opposed to `undef` bcause it can help spot typos and is very helpful when doing big reorganizations in the code.

* player: merge mp_osd.h into mp_core.hwm42013-10-301-1/+0
| | | | | | | | Just doing this because mp_osd.h and osd.c is not consistent. There are some other header files (command.h and screenshot.h), but since I don't feel too good about inflating mp_core.h, I'm not merging them, at least not yet.
* Split mplayer.cwm42013-10-301-0/+1297
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.
