* Relicense some non-MPlayer source files to LGPL 2.1 or laterwm42016-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This covers source files which were added in mplayer2 and mpv times only, and where all code is covered by LGPL relicensing agreements. There are probably more files to which this applies, but I'm being conservative here. A file named ao_sdl.c exists in MPlayer too, but the mpv one is a complete rewrite, and was added some time after the original ao_sdl.c was removed. The same applies to vo_sdl.c, for which the SDL2 API is radically different in addition (MPlayer supports SDL 1.2 only). common.c contains only code written by me. But common.h is a strange case: although it originally was named mp_common.h and exists in MPlayer too, by now it contains only definitions written by uau and me. The exceptions are the CONTROL_ defines - thus not changing the license of common.h yet. codec_tags.c contained once large tables generated from MPlayer's codecs.conf, but all of these tables were removed. From demux_playlist.c I'm removing a code fragment from someone who was not asked; this probably could be done later (see commit 15dccc37). misc.c is a bit complicated to reason about (it was split off mplayer.c and thus contains random functions out of this file), but actually all functions have been added post-MPlayer. Except get_relative_time(), which was written by uau, but looks similar to 3 different versions of something similar in each of the Unix/win32/OSX timer source files. I'm not sure what that means in regards to copyright, so I've just moved it into another still-GPL source file for now. screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but they're all gone.
* player: refactor: eliminate MPContext.d_videowm42016-01-171-1/+8
| | | | | | | | | | | | | | Eventually we want the VO be driven by a A->V filter, so a decoder doesn't even have to exist. Some features definitely require a decoder though (like reporting the decoder in use, hardware decoding, etc.), so for each thing which accessed d_video, it has to be redecided if and how it can access decoder state. At least the "framedrop" property slightly changes semantics: you can now always set this property, even if no video is active. Some untested changes in this commit, but our bio-based distributed test suite has to take care of this.
* player: refactor: eliminate MPContext.d_subwm42016-01-171-4/+4
| | | | The same is going to happen to d_video and d_audio later.
* video: refactor: disentangle decoding/filtering some morewm42016-01-161-4/+9
| | | | | | | | | | | This moves some code related to decoding from video.c to dec_video.c, and also removes some accesses to dec_video.c from the filtering code. dec_video.ch is starting to make sense, and simply returns video frames from a demuxer stream. The API exposed is also somewhat intended to be easily changeable to move decoding to a separate thread, if we ever want this (due to libavcodec already being threaded, I don't see much of a reason, but it might still be helpful).
* player: remove unused last_dvb_step member.Oliver Freyermuth2016-01-141-2/+0
| | | | | | Channel switching is treated inside the global DVB state by now. Anyways the last switching direction is not really useful and of no interest inside the player.
* video: decouple filtering/decoding slightly morewm42016-01-141-3/+13
| | | | | | | | | | | | | | | | | | | Lots of noise to remove the vfilter/vo fields from dec_video. From now on, video filtering and output will still be done together, summarized under struct vo_chain. There is the question where exactly the vf_chain should go in such a decoupled architecture. The end goal is being able to place a "complex" filter between video decoders and output (which will culminate in natural integration of A->V filters for natural integration of libavfilter audio visualizations). The vf_chain is still useful for "final" processing, such as format conversions and deinterlacing. Also, there's only 1 VO and 1 --vf option. So having 1 vf_chain for a VO seems ideal, since otherwise there would be no natural way to handle all these existing options and mechanisms. There is still some work required to truly decouple decoding.
* player: remove stale declarationwm42016-01-141-1/+0
|
* video: refactor: shuffle code aroundwm42016-01-141-0/+3
| | | | | | struct dec_video should have nothing to do with video filters or outputs, and this huge chunk of code was somehow stuck directly in dec_video.c.
* player: simplify backsteppingwm42016-01-121-11/+6
| | | | | | | | | | | | | | Basically reimplement it. The old implementation was quite stupid, and was probably done this way because video filtering and output used to be way less decoupled. Now we can reimplement it in a very simple way: when backstepping, seek to current time, but keep the last frame that was supposed to be discarded when reaching the target time. When the seek finishes, prepend the saved frame to the video frame queue. A disadvantage is that the new implementation fails to skip over timeline boundaries (ordered chapters etc.), but this never worked properly anyway. It's possible that this will be fixed some time in the future.
* player: eliminate demux_get_next_pts()wm42016-01-111-1/+0
| | | | | | | | | | | | | | | | This slightly changes behavior when seeking with external audio/subtitle tracks if transport streams and mpeg files are played, as well as behavior when seeking with such external tracks. get_main_demux_pts() is evil because it always blocks on the demuxer (if there isn't already a packet queued). Thus it could lock up the player, which is a shame because all other possible causes have been removed. The reduced "precision" when seeking in the ts/mpeg cases (where SEEK_FACTOR is used, resulting in byte seeks instead of timestamp seeks) might lead to issues. We should probably drop this heuristic. (It was introduced because there is no other way to seek in files with PTS resets with libavformat, but its value is still questionable.)
* sub: change how subtitles are readwm42015-12-291-1/+1
| | | | | | | | Slightly change how it is decided when a new packet should be read. Switch to demux_read_packet_async(), and let the player "wait properly" until required subtitle packets arrive, instead of blocking everything. Move distinguishing the cases of passive and active reading into the demuxer, where it belongs.
* sub: always recreate ASS_Renderer on subtitle decoder reinitwm42015-12-261-10/+0
| | | | | | | This includes the case of switching ordered chapter boundaries. It will now be recreated on each timeline part switch. This shouldn't be much of a problem with modern libass. (Older libass versions use fontconfig for memory fonts, and will be very slow to reinitialize memory fonts.)
* sub: cache subtitle state per track instead of per demuxer streamwm42015-12-261-1/+3
| | | | | | | | | | | | Since commit 6d9cb893, subtitle state doesn't survive timeline switches (ordered chapters etc.). So there is no point in caching the state per sh_stream anymore (which would be required to deal with multiple segments). Move the cache to struct track. (Whether it's worth caching the subtitle state just for the situation when subtitle tracks get reselected is questionable. But for now, it's nice to have the subtitles immediately show up when reselecting a subtitle.)
* player: minor simplificationwm42015-12-231-1/+1
| | | | This tmp thing had not much of a purpose anymore.
* player: always disable display-sync on desyncswm42015-11-271-0/+1
| | | | | | | | | | | | | | | Instead of periodically trying to enable it again. There are two cases that can happen: 1. A random discontinuity messed everything up, 2. Things are just broken and will desync all the time Until now, it tried to deal with case 1 - but maybe this is really rare, and we don't really need to care about it. On the other hand, case 2 is kind of hard to diagnose if the user doesn't use the terminal. Seeking will reenable display-sync, so you can fix playback if case 1 happens, but still get predictable behavior in case 2.
* player: make timeline switching slightly nicerwm42015-11-181-1/+1
| | | | But not much.
* player: remove OSD subtitle render pathwm42015-11-171-3/+1
| | | | | | | | | | | | | | | | | | | This was used with --no-sub-ass (aka --no-ass). This option (which is not yet removed) strips all styling from the subtitles, and renders them as plaintext only. For some reason, it originally seemed convenient to reuse all the OSD text rendering code (osd_libass.c). While this was indeed simple, it had a bad influence on the rest of the code. For example, it had to decide whether to go through the OSD code path, or the proper subtitle renderer in sd_ass.c. Kill the OSD subtitle renderer. Reimplement --no-sub-ass and also "secondary" subtitles in sd_ass.c. fill_plaintext() contains some rather minor code duplication with osd_libass.c for setting up a dummy ASS_Event and escaping the stripped text. Since sd_ass.c already has to handle "normal" text subtitles, and has code for stripping ASS tags, this remains all relatively simple. Remove all the unnecessary crap from the rest of the code.
* player: use demuxer ts offset to simplify timeline ts handlingwm42015-11-161-3/+2
| | | | | | | | | Use the demux_set_ts_offset() added in the previous commit to base each timeline segment to use timestamps according to its relative position within the overall timeline. As a consequence we don't need to care about these timestamps anymore, and everything becomes simpler. (Another minor but delicious nugget of sanity.)
* player: handle rebasing start time differentlywm42015-11-161-1/+0
| | | | | | | | | | | | | | | | Most of this is explained in the DOCS additions. This gives us slightly more sanity, because there is less interaction between the various parts. The goal is getting rid of the video_offset entirely. The simplification extends to the user API. In particular, we don't need to fix missing parts in the API, such as the lack for a seek command that seeks relatively to the start time. All these things are now transparent. (If someone really wants to know the real timestamps/start time, new properties would have to be added.)
* win32: support taskbar button progress indicatorMartin Herkt2015-11-151-0/+2
| | | | | | | | | | | This adds support for the progress indicator taskbar extension that was introduced with Windows 7 and Windows Server 2008 R2. I don’t like this solution because it keeps its own state and introduces another VOCTRL, but I couldn’t come up with anything less messy. closes #2399
* player: remove unused fieldwm42015-11-141-1/+0

* player: try to compensate actual audio driftwm42015-11-131-0/+1
| | | | | | | | | | | | | | | | We always let audio slowly desync until a threshold is reached, and then pushed it back by applying a maximum compensation speed. Refine what comes afterwards: instead of playing with the nominal video speed, use the actual required audio speed for keeping sync as measured by the A/V difference. (The "actual" speed is the ideal speed with A/V differences added.) Although this works in theory, it's somewhat questionable how much this works in practice. The ideal time value is actually not exact, but is the time at which the frame is scheduled (could be compensated by using the time_left calculations in handle_display_sync_frame()). It doesn't account for speed changes or catastrophic discontinuities. It uses only 10 past frames.
* player: remove display_sync_disable_counterwm42015-11-131-1/+0
| | | | We can implement it differently and drop a tiny bit of state.
* command: add vsync-ratio propertywm42015-11-131-0/+1
| | | | | | | | This is very "illustrative", unlike the video-speed-correction property, and thus useful. It can also be used to observe scheduling errors, which are not detected by the core. (These happen due to rounding errors; possibly not evne our fault, but coming from files with rounded timestamps and so on.)
* player: refactor display-sync frame duration calculationswm42015-11-131-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of get_past_frame_durations(), which was a bit too messy. Add a past_frames array, which contains the same information in a more reasonable way. This also means that we can get the exact current and past frame durations without going through awful stuff. (The main problem is that vo_pts_history contains future frames as well, which is needed for frame backstepping etc., but gets in the way here.) Also disable the automatic disabling of display-sync if the frame duration changes, and extend the frame durations allowed for display sync. To allow arbitrarily high durations, vo.c needs to be changed to pause and potentially redraw OSD while showing a single frame, so they're still limited. In an attempt to deal with VFR, calculate the overall speed using the average FPS. The frame scheduling itself does not use the average FPS, but the duration of the current frame. This does not work too well, but provides a good base for further improvements. Where this commit actually helps a lot is dealing with rounded timestamps, e.g. if the container framerate is wrong or unknown, or if the muxer wrote incorrectly rounded timestamps. While the rounding errors apparently can't be get rid of completely in the general case, this is still much better than e.g. disabling display-sync completely just because some frame durations go out of bounds.
* player: limit speed change in display-sync adrop modewm42015-11-031-0/+1
| | | | | | | | | | Discontinuities (like toggling fullscreen) can cause multiple frames to be dropped in succession, which sounds very weird. It's better to drop some video frames instead to compensate for larger desyncs. We roughly base it on the maximum allowed speed changes (audio change is "additional" to the video change to account for deviations when playing at max. video speed change).
* command: add mistimed-frame-count propertywm42015-10-301-0/+2
| | | | | Does what the manpage says. This is a replacement incrementing the dropped frame counter (see previous commit).
* player: add audio drop/duplicate modewm42015-10-271-0/+2
| | | | Not very robust in the moment.
* audio: add AO deviation loggingwm42015-10-081-0/+3
| | | | | Pretty dumb (and doesn't handle pausing or other discontinuities), but at least somewhat idiot-proof.
* player: some more --force-window fixeswm42015-09-211-1/+1
| | | | | | | | | | | | | Sigh... After the recent changes, another regression appeared. This time, the VO window wasn't cleared when changing from video to a non- video file (such as audio-only with no cover art). Fix this by properly taking the handle_force_window() bool parameter into account. Also, the info message could be printed twice, which is harmless but ugly. So just remove the message. Also, do some more minor cleanups (like fixing the comment, which was completely outdated).
* player: make force-window in auto-profiles actually workwm42015-09-201-1/+1
| | | | | | | | | | | The previous commit was incomplete (and I didn't notice due to a broken test procedure). The annoying part is that actually creating the VO was separate; redo this and merge the code for this into handle_force_window() as well. This will also make implementing proper reaction to runtime option changes easier. (Only the part for actually listening to option changes is missing.)
* player: add display sync modewm42015-08-101-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | If this mode is enabled, the player tries to strictly synchronize video to display refresh. It will adjust playback speed to match the display, so if you play 23.976 fps video on a 24 Hz screen, playback speed is increased by approximately 1/1000. Audio wll be resampled to keep up with playback. This is different from the default sync mode, which will sync video to audio, with the consequence that video might skip or repeat a frame once in a while to make video keep up with audio. This is still unpolished. There are some major problems as well; in particular, mkv VFR files won't work well. The reason is that Matroska is terrible and rounds timestamps to milliseconds. This makes it rather hard to guess the framerate of a section of video that is playing. We could probably fix this by just accepting jittery timestamps (instead of explicitly disabling the sync code in this case), but I'm not ready to accept such a solution yet. Another issue is that we are extremely reliant on OS video and audio APIs working in an expected manner, which of course is not too often the case. Consequently, the new sync mode is a bit fragile.
* player: separate controls for user and video controlled speedwm42015-08-101-1/+7
| | | | | | | | | | For video sync, we want separate playback speed controls for user- requested speed and the "correction" speed for video timing. 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).
* player: redo estimated-vf-fps calculationwm42015-08-101-0/+5
| | | | | | | | | | | | | | Additionally to taking the average, this tries to use the demuxer FPS to eliminate jitter, and applies some other heuristics to check if the result is sane. This code will also be used for the display sync code (it will actually make use of the require_exact parameter). (The value of doing this over keeping the simpler demux_mkv hack is somewhat questionable. But at least it allows us to deal with other container formats that use jittery timestamps, such as mp4 remuxed from mkv.)
* player: remove higher-level remains of DVD/BD menu supportwm42015-08-031-10/+0
| | | | | | | | | | | | | | | Nobody wanted to restore this, so it gets the boot. If anyone still wants to volunteer to restore menu support, this would be welcome. (I might even try it myself if I feel masochistic and like wasting a lot of time for nothing.) But if it does get restored, it should be done differently. There were many stupid things about how it was done. For example, it somehow tried to pull mp_nav_events through all the layers (including needing to "buffer" them in the demuxer), which was needlessly complicated. It could be done simpler. This code was already inactive, so this commit actually changes nothing. Also keep in mind that normal DVD/BD playback still works.
* vo: minor simplification for queue size handlingwm42015-07-201-1/+1
| | | | | | | | | | Instead of calling it "future frames" and adding or subtracting 1 from it, always call it "requested frames". This simplifies it a bit. MPContext.next_frames had 2 added to it; this was mainly to ensure a minimum size of 2. Drop it and assume VO_MAX_REQ_FRAMES is at least 2; together with the other changes, this can be the exact size of the array.
* player: refactor chapter seek codewm42015-07-101-1/+0
| | | | | | | mp_seek_chapter() had only 1 caller. Also the code was rather roundabout; the entire function can be compressed to 5 lines of code. (The new code is functionally the same - "mpctx->last_chapter_seek = -2;" was effectively a dead assingment.)
* player: add missing include directivewm42015-07-061-0/+1
|
* sub: protect ASS_Renderer statewm42015-07-061-0/+1
| | | | | | | | | | | | | | | | | | | Each subtitle track gets its own decoder instance (sd_ass). But they use a shared ASS_Renderer. This is done mainly because of fontconfig. Initializing fontconfig is very slow when using it with memory fonts, so there's a practical need to cache this memory font state, which is done by not creating separate ASS_Renderers. This is very dirty and very evil, but we probably can't get rid of it any time soon. The shared ASS_Renderer was not properly synchronized. While the program logic guarantees that only one sd_ass instance is visible at a time, there are other interactions that require synchronization. In particular, I suspect concurrent execution of mp_ass_configure_fonts() and sd_ass.get_bitmaps cause issues in a newer libass development branch. So here's a shitty hack that hopefully fixes things, hopefully only until libass becomes less dependent on fontconfig.
* player: simplify reload logicwm42015-07-021-1/+1
| | | | Instead of only reloading the demuxer, reopen the stream as well.
* player: unentangle --stream-dumpwm42015-07-021-1/+1
| | | | | | | | The final goal is making opening the demuxer and opening the stream the same operation. Stream dumping is a rather uninteresting feature, but has a small number of vocal users, and it's easy to keep.
* video: pass future frames to VOwm42015-07-011-1/+3
| | | | | | | | | | Now the VO can request a number of future frames with the last parameter of vo_set_queue_params(). This will be helpful to fix the interpolation code. Note that the first frame (after playback start or seeking) will usually not have any future frames (to make seeking fast). Near the end of the file, the number of future frames will become lower as well.
* demux: export forced flagwm42015-06-271-1/+1
| | | | | | At least Matroska files have a "forced" flag (in addition to the "default" flag). Export this flag. Treat it almost like the default flag, but with slightly higher priority.
* player: print a message along with track listwm42015-06-031-1/+1
| | | | Slightly less strange.
* player: fix crashes when adding external tracks before loading main filewm42015-05-261-4/+3
| | | | | | | | | | | | | | | | Adding an external audio track before loading the main file didn't work right. For one, mp_switch_track() assumes it is called after the main file is loaded. (The difference is that decoders are only initialized once the main file is loaded, and we avoid doing this before that for whatever reason.) To avoid further messiness, just allow mp_switch_track() to be called at any time. Also make it do what mp_mark_user_track_selection() did, since the latter requires current_track to be set. (One could probably simply allow current_track to be set at this point, but it'd interfere with default track selection anyway and thus would be pointless.) Fixes #1984.
* player: add function to compute past frame durationswm42015-05-241-0/+1
| | | | | And use it for the estimated-vf-fps property (it should be doing the same as before).
* player: use an array for stream ID options and suchwm42015-05-221-2/+2
| | | | This makes the code slightly more generic.
* player: make resuming playlists less noisy in verbose modewm42015-05-091-0/+2
| | | | | | | | | | | | | | | | | | | mp_find_config_file() will print the filename lookup and its result in verbose mode. This is wanted, but gets inconvenient when it is done for every playlist entry (for resuming). Lookup the watch_later subdir only once and cache the result instead. This drops the logic for loading the resume file from other locations, which should generally be unnecessary, though might lead to confusion if the user has mixed old and new config paths (which the user shouldn't). Also add a mp_find_user_config_file() function for a more straightforward and reliable way to get actual local configpaths, instead of possibly global and unwritable locations. Also, for symmetry, check the resume option in mp_load_playback_resume() just like mp_check_playlist_resume() does.
* build: move main-fn files to osdepwm42015-05-021-1/+0
| | | | | | And split the Cocoa and Unix cases. Simplify the Cocoa case slightly by calling mpv_main directly, instead of passing a function pointer. Also add a comment explaining why Cocoa needs a special case at all.
* player: log track list when adding or removing external fileswm42015-04-281-0/+1
