* player: do not update OSD all the time when pausedwm42016-06-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, OSD is updated every time the playloop is run. This has to be done, because the OSD may implicitly reference various properties, without knowing whether they really need to be updated or not. (There's a property update mechanism, but it's mostly unavailable, because OSD is special-cased and can not use the client API mechanism properly.) Normally, these updates are no problem, because the OSD is only actually printed when the OSD text actually changes. But commit d23ffd24 added a rate-limiting mechanism, which tries to limit OSD updates at most every 50ms (or the next video frame). Since it can't know in advance whether the OSD is going to change or not, this simply waked up the player every 50ms. Change this so that the player is updated only as part of general updates determined through mp_notify(). (This function also notifies the client API of changed properties.) The desired result is that the player will not wake up at all in normal idle mode, but still update properties that can change when paused, such as the cache. This is mostly a cosmetic change (in the sense of making runtime behavior just slightly better). It has the slightly more negative consequence that properties which update implicitly (such as "clock") will not update periodically anymore.
* video: refactor how VO exports hwdec device handleswm42016-05-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The main change is with video/hwdec.h. mp_hwdec_info is made opaque (and renamed to mp_hwdec_devices). Its accessors are mainly thread-safe (or documented where not), which makes the whole thing saner and cleaner. In particular, thread-safety rules become less subtle and more obvious. The new internal API makes it easier to support multiple OpenGL interop backends. (Although this is not done yet, and it's not clear whether it ever will.) This also removes all the API-specific fields from mp_hwdec_ctx and replaces them with a "ctx" field. For d3d in particular, we drop the mp_d3d_ctx struct completely, and pass the interfaces directly. Remove the emulation checks from vaapi.c and vdpau.c; they are pointless, and the checks that matter are done on the VO layer. The d3d hardware decoders might slightly change behavior: dxva2-copy will not use the VO device anymore if the VO supports proper interop. This pretty much assumes that any in such cases the VO will not use any form of exclusive mode, which makes using the VO device in copy mode unnecessary. This is a big refactor. Some things may be untested and could be broken.
* player: simplify an aspect of buffering determinationwm42016-04-191-1/+2
| | | | | | | | | | | | | | | Calculate the buffering percentage in the same code which determines whether the player is or should be buffering. In particular it can't happen that percentage and buffering state are slightly out of sync due to calling DEMUXER_CTRL_GET_READER_STATE and reusing it with the previously determined buffering state. Now it's also easier to guarantee that the buffering state is updated properly. Add some more verbose output as well. (Damn I hate this code, why did I write it?)
* sub: make preloading more robustwm42016-03-061-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subtitles can be preloaded, which means they're fully read and copied into ASS_Track. This in turn is mainly for the sake of being able to do subtitle seeking (when it comes down to it, subtitle seeking is the cause for most trouble here). Commit a714f8e92 broke preloaded subtitles which have events with unknown duration, such as some MicroDVD samples. The event list gets cleared on every seek, so the property of being preloaded obviously gets lost. Fix this by moving most of the preloading logic to dec_sub.c. If the subtitle list gets cleared, they are not considered preloaded anymore, and the logic for demuxed subtitles is used. As another minor thing, preloadeding subtitles did neither disable the demux stream, nor did it discard packets. Thus you could get queue overflows in theory (harmless, but annoying). Fix this by explicitly discarding packets in preloaded mode. In summary, now the only difference between preloaded and normal demuxing are: 1. a seek is issued, and all packets are read on start 2. during playback, discard the packets instead of feeding them to the subtitle decoder This is still petty annoying. It would be nice if maintaining the subtitle index (and maybe a subtitle packet cache for instant subtitle presentation when seeking back) could be maintained in the demuxer instead. Half of all file formats with interleaved subtitles have this anyway (mp4, mkv muxed with newer mkvmerge).
* player: minor simplificationwm42016-02-271-2/+2
| | | | | | No need to pass endpts down in such a dumb way. Also remove an outdated comment somewhere.
* player: slightly simplify how demuxer streams are enabled/disabledwm42016-02-251-1/+1
| | | | | Instead of having reselect_demux_streams() look at all streams, make it look at the current stream that is being enabled/disabled.
* player: remove unused MPContext.stream fieldwm42016-02-231-2/+0
| | | | | | | It was just dead code. Also fixes the stream-open-filename property, which is supposed to be read-only if a file was already opened.
* player: remove MPContext.sources fieldswm42016-02-231-2/+0
| | | | | | Some oddity that is not needed anymore. The only thing which still referenced them was avoiding loading external files more than once, which is now prevented by checking the list of tracks instead.
* player: remove old timeline/ordered chapters supportwm42016-02-151-20/+1
|
* player: add complex filter graph supportwm42016-02-051-0/+17
| | | | | | | | | | | | | | | | See --lavfi-complex option. This is still quite rough. There's no support for dynamic configuration of any kind. There are probably corner cases where playback might freeze or burn 100% CPU (due to dataflow problems when interaction with libavfilter). Future possible plans might include: - freely switch tracks by providing some sort of default track graph label - automatically enabling audio visualization - automatically mix audio or stack video when multiple tracks are selected at once (similar to how multiple sub tracks can be selected)
* player: move audio and video decoder init to separate functionswm42016-02-051-0/+2
| | | | Preparation.
* player: use different variable to indicate coverartwm42016-02-011-3/+4
| | | | Slightly better.
* audio: move pts reset checkwm42016-01-291-0/+1
| | | | Reduces the dependency of the filter/output code on the decoder.
* player: fix initial audio sync in certain caseswm42016-01-291-2/+0
| | | | | | | | | | | | | | | | | Regression caused by commit 3b95dd47. Also see commit 4c25b000. We can either use video_next_pts and add "delay", or we just use video_pts. Any other combination breaks. The reason why the assumption that delay==0 at this point was wrong exactly because after displaying the first video frame (usually done before audio resync) a new frame might be "added" immediately, resulting in a new video_next_pts and "delay", which will still amount to video_pts. Fixes #2770. (The reason why display-sync was blamed in this issue is because enabling display-sync in the options forces a prefetch by 2 instead of 1 frames for seeks/playback restart, which triggers the issue, even if display-sync is not actually enabled. In this case, display-sync is never enabled because the frames have a unusually high frame duration. This is also what exposed the initial desync issue.)
* audio: refactor: move MPContext.ao_buffer fieldwm42016-01-221-1/+1
| | | | | | | | | | | | It doesn't need to be part of the big context, but is strictly part of shuffling data from the audio filters to audio output, and thus belongs into ao_chain. It also turns out that clearing it in clear_audio_output_buffers() is completely redundant. (Of course ao_buffer is an abomination in the first place and shouldn't exist at all.)
* player: refactor: eliminate MPContext.d_audiowm42016-01-221-3/+2
|
* audio: refactor: work towards unentangling audio decoding and filteringwm42016-01-221-0/+21
| | | | | | | | | 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.
* 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.)
