Implement vsync-aware frame timing for VDPAU Main things added are custom frame dropping for VDPAU to work around the display FPS limit, frame timing adjustment to avoid jitter when video frame times keep falling near vsyncs, and use of VDPAU's timing feature to keep one future frame queued in advance. NVIDIA's VDPAU implementation refuses to change the displayed frame more than once per vsync. This set a limit on how much video could be sped up, and caused problems for nearly all videos on low-FPS video projectors (playing 24 FPS video on a 24 FPS projector would not work reliably as MPlayer may need to slightly speed up the video for AV sync). This commit adds a framedrop mechanism that drops some frames so that no more than one is sent for display per vsync. The code tries to select the dropped frames smartly, selecting the best one to show for each vsync. Because of the timing features needed the drop functionality currently does not work if the correct-pts option is disabled. The code also adjusts frame timing slightly to avoid jitter. If you for example play 24 FPS video content on a 72 FPS display then normally a frame would be shown for 3 vsyncs, but if the frame times happen to fall near vsyncs and change between just before and just after then there could be frames alternating between 2 and 4 vsyncs. The code changes frame timing by up to one quarter vsync interval to avoid this. The above functionality depends on having reliable vsync timing information available. The display refresh rate is not directly provided by the VDPAU API. The current code uses information from the XF86VidMode extension if available; I'm not sure how common cases where that is inaccurate are. The refresh rate can be specified manually if necessary. After the changes in this commit MPlayer now always tries to keep one frame queued for future display using VDPAU's internal timing mechanism (however no more than 50 ms to the future). This should make video playback somewhat more robust against timing inaccuracies caused by system load.

vdpau: split off decoder parts, use "new" libavcodec vdpau hwaccel API Move the decoder parts from vo_vdpau.c to a new file vdpau_old.c. This file is named so because because it's written against the "old" libavcodec vdpau pseudo-decoder (e.g. "h264_vdpau"). Add support for the "new" libavcodec vdpau support. This was recently added and replaces the "old" vdpau parts. (In fact, Libav is about to deprecate and remove the "old" API without deprecation grace period, so we have to support it now. Moreover, there will probably be no Libav release which supports both, so the transition is even less smooth than we could hope, and we have to support both the old and new API.) Whether the old or new API is used is checked by a configure test: if the new API is found, it is used, otherwise the old API is assumed. Some details might be handled differently. Especially display preemption is a bit problematic with the "new" libavcodec vdpau support: it wants to keep a pointer to a specific vdpau API function (which can be driver specific, because preemption might switch drivers). Also, surface IDs are now directly stored in AVFrames (and mp_images), so they can't be forced to VDP_INVALID_HANDLE on preemption. (This changes even with older libavcodec versions, because mp_image always uses the newer representation to make vo_vdpau.c simpler.) Decoder initialization in the new code tries to deal with codec profiles, while the old code always uses the highest profile per codec. Surface allocation changes. Since the decoder won't call config() in vo_vdpau.c on video size change anymore, we allow allocating surfaces of arbitrary size instead of locking it to what the VO was configured. The non-hwdec code also has slightly different allocation behavior now. Enabling the old vdpau special decoders via e.g. --vd=lavc:h264_vdpau doesn't work anymore (a warning suggesting the --hwdec option is printed instead).

core/VO: Allow VO drivers to add/modify frames Add interfaces to allow VO drivers to add or remove frames from the video stream and to alter timestamps. Currently this functionality only works with in correct-pts mode. Use the new functionality in vo_vdpau to properly support frame-adding deinterlace modes. Frames added by the VDPAU deinterlacing code are now properly timed. Before every second frame was always shown immediately (probably next monitor refresh) after the previous one, even if you were watching things in slow motion, and framestepping didn't stop at them at all. When seeking the deinterlace algorithm is no longer fed a mix of frames from old and new positions. As a side effect of the changes a problem with resize events was also fixed. Resizing calls video_to_output_surface() to render the frame at the new resolution, but before this function also changed the list of history frames, so resizing could give an image different from the original one, and also corrupt next frames due to them seeing the wrong history. Now the function has no such side effects. There are more resize-related problems though that will be fixed in a later commit. The deint_mpi[] list of reserved frames is increased from 2 to 3 entries for reasons related to the above. Having 2 entries is enough when you initially get a new frame in draw_image() because then you'll have those two entries plus the new one for a total of 3 (the code relied on the oldest mpi implicitly staying reserved for the duration of the call even after usage count was decreased). However if you want to be able to reproduce the rendering outside draw_image(), relying on the explicitly reserved list only, then it needs to store 3 entries.

However if you want to be able to reproduce the rendering outside draw_image(), relying on the explicitly reserved list only, then it needs to store 3 entries.

Implement vsync-aware frame timing for VDPAU Main things added are custom frame dropping for VDPAU to work around the display FPS limit, frame timing adjustment to avoid jitter when video frame times keep falling near vsyncs, and use of VDPAU's timing feature to keep one future frame queued in advance. NVIDIA's VDPAU implementation refuses to change the displayed frame more than once per vsync. This set a limit on how much video could be sped up, and caused problems for nearly all videos on low-FPS video projectors (playing 24 FPS video on a 24 FPS projector would not work reliably as MPlayer may need to slightly speed up the video for AV sync). This commit adds a framedrop mechanism that drops some frames so that no more than one is sent for display per vsync. The code tries to select the dropped frames smartly, selecting the best one to show for each vsync. Because of the timing features needed the drop functionality currently does not work if the correct-pts option is disabled. The code also adjusts frame timing slightly to avoid jitter. If you for example play 24 FPS video content on a 72 FPS display then normally a frame would be shown for 3 vsyncs, but if the frame times happen to fall near vsyncs and change between just before and just after then there could be frames alternating between 2 and 4 vsyncs. The code changes frame timing by up to one quarter vsync interval to avoid this. The above functionality depends on having reliable vsync timing information available. The display refresh rate is not directly provided by the VDPAU API. The current code uses information from the XF86VidMode extension if available; I'm not sure how common cases where that is inaccurate are. The refresh rate can be specified manually if necessary. After the changes in this commit MPlayer now always tries to keep one frame queued for future display using VDPAU's internal timing mechanism (however no more than 50 ms to the future). This should make video playback somewhat more robust against timing inaccuracies caused by system load.

vdpau: split off decoder parts, use "new" libavcodec vdpau hwaccel API Move the decoder parts from vo_vdpau.c to a new file vdpau_old.c. This file is named so because because it's written against the "old" libavcodec vdpau pseudo-decoder (e.g. "h264_vdpau"). Add support for the "new" libavcodec vdpau support. This was recently added and replaces the "old" vdpau parts. (In fact, Libav is about to deprecate and remove the "old" API without deprecation grace period, so we have to support it now. Moreover, there will probably be no Libav release which supports both, so the transition is even less smooth than we could hope, and we have to support both the old and new API.) Whether the old or new API is used is checked by a configure test: if the new API is found, it is used, otherwise the old API is assumed. Some details might be handled differently. Especially display preemption is a bit problematic with the "new" libavcodec vdpau support: it wants to keep a pointer to a specific vdpau API function (which can be driver specific, because preemption might switch drivers). Also, surface IDs are now directly stored in AVFrames (and mp_images), so they can't be forced to VDP_INVALID_HANDLE on preemption. (This changes even with older libavcodec versions, because mp_image always uses the newer representation to make vo_vdpau.c simpler.) Decoder initialization in the new code tries to deal with codec profiles, while the old code always uses the highest profile per codec. Surface allocation changes. Since the decoder won't call config() in vo_vdpau.c on video size change anymore, we allow allocating surfaces of arbitrary size instead of locking it to what the VO was configured. The non-hwdec code also has slightly different allocation behavior now. Enabling the old vdpau special decoders via e.g. --vd=lavc:h264_vdpau doesn't work anymore (a warning suggesting the --hwdec option is printed instead).

Implement vsync-aware frame timing for VDPAU Main things added are custom frame dropping for VDPAU to work around the display FPS limit, frame timing adjustment to avoid jitter when video frame times keep falling near vsyncs, and use of VDPAU's timing feature to keep one future frame queued in advance. NVIDIA's VDPAU implementation refuses to change the displayed frame more than once per vsync. This set a limit on how much video could be sped up, and caused problems for nearly all videos on low-FPS video projectors (playing 24 FPS video on a 24 FPS projector would not work reliably as MPlayer may need to slightly speed up the video for AV sync). This commit adds a framedrop mechanism that drops some frames so that no more than one is sent for display per vsync. The code tries to select the dropped frames smartly, selecting the best one to show for each vsync. Because of the timing features needed the drop functionality currently does not work if the correct-pts option is disabled. The code also adjusts frame timing slightly to avoid jitter. If you for example play 24 FPS video content on a 72 FPS display then normally a frame would be shown for 3 vsyncs, but if the frame times happen to fall near vsyncs and change between just before and just after then there could be frames alternating between 2 and 4 vsyncs. The code changes frame timing by up to one quarter vsync interval to avoid this. The above functionality depends on having reliable vsync timing information available. The display refresh rate is not directly provided by the VDPAU API. The current code uses information from the XF86VidMode extension if available; I'm not sure how common cases where that is inaccurate are. The refresh rate can be specified manually if necessary. After the changes in this commit MPlayer now always tries to keep one frame queued for future display using VDPAU's internal timing mechanism (however no more than 50 ms to the future). This should make video playback somewhat more robust against timing inaccuracies caused by system load.

vo_vdpau: simplify time management and make it more robust vo_vdpau used a somewhat complicated and fragile mechanism to convert the vdpau time to internal mpv time. This was fragile as in it couldn't deal well with Mesa's (apparently) random timestamps, which can change the base offset in multiple situations. It can happen when moving the mpv window to a different screen, and somehow it also happens when pausing the player. It seems this mechanism to synchronize the vdpau time is not actually needed. There are only 2 places where sync_vdptime() is used (i.e. returning the current vdpau time interpolated by system time). The first call is for determining the PTS used to queue a frame. This also uses convert_to_vdptime(). It's easily replaced by querying the time directly, and adding the wait time to it (rel_pts_ns in the patch). The second call is pretty odd: it updates the vdpau time a second time in the same function. From what I can see, this can matter only if update_presentation_queue_status() is very slow. I'm not sure what to make out of this, because the call merely queries the presentation queue. Just assume it isn't slow, and that we don't have to update the time. Another potential issue with this is that we call VdpPresentationQueueGetTime() every frame now, instead of every 5 seconds and interpolating the other calls via system time. More over, this is per video frame (which can be portantially dropped, and not per actually displayed frame. Assume this doesn't matter. This simplifies the code, and should make it more robust on Mesa. But note that what Mesa does is obviously insane - this is one situation where you really need a stable time source. There are still plenty of race condition windows where things can go wrong, although this commit should drastically reduce the possibility of this. In my tests, everything worked well. But I have no access to a Mesa system with vdpau, so it needs testing by others. See github issues #520, #694, #695.

/* This should normally never happen.
* - The last queued frame can't have a PTS that goes more than 50ms in the
video: move display and timing to a separate thread The VO is run inside its own thread. It also does most of video timing. The playloop hands the image data and a realtime timestamp to the VO, and the VO does the rest. In particular, this allows the playloop to do other things, instead of blocking for video redraw. But if anything accesses the VO during video timing, it will block. This also fixes vo_sdl.c event handling; but that is only a side-effect, since reimplementing the broken way would require more effort. Also drop --softsleep. In theory, this option helps if the kernel's sleeping mechanism is too inaccurate for video timing. In practice, I haven't ever encountered a situation where it helps, and it just burns CPU cycles. On the other hand it's probably actively harmful, because it prevents the libavcodec decoder threads from doing real work. Side note: Originally, I intended that multiple frames can be queued to the VO. But this is not done, due to problems with OSD and other certain features. OSD in particular is simply designed in a way that it can be neither timed nor copied, so you do have to render it into the video frame before you can draw the next frame. (Subtitles have no such restriction. sd_lavc was even updated to fix this.) It seems the right solution to queuing multiple VO frames is rendering on VO-backed framebuffers, like vo_vdpau.c does. This requires VO driver support, and is out of scope of this commit. As consequence, the VO has a queue size of 1. The existing video queue is just needed to compute frame duration, and will be moved out in the next commit.

* integer values) 0.01, 1.99, 4.01, 5.99, 8.01, ... then
* straightforward timing at next vsync would flip the frames at
* 1, 2, 5, 6, 9; this changes it to 1, 2, 4, 6, 8 and so on with
* regular 2-vsync intervals.
*
* Also allow moving the frame forward if it looks like we dropped
* the previous frame incorrectly (now that we know better after
* having final exact timestamp information for this frame) and
* there would unnecessarily be a vsync without a frame change.

Implement vsync-aware frame timing for VDPAU Main things added are custom frame dropping for VDPAU to work around the display FPS limit, frame timing adjustment to avoid jitter when video frame times keep falling near vsyncs, and use of VDPAU's timing feature to keep one future frame queued in advance. NVIDIA's VDPAU implementation refuses to change the displayed frame more than once per vsync. This set a limit on how much video could be sped up, and caused problems for nearly all videos on low-FPS video projectors (playing 24 FPS video on a 24 FPS projector would not work reliably as MPlayer may need to slightly speed up the video for AV sync). This commit adds a framedrop mechanism that drops some frames so that no more than one is sent for display per vsync. The code tries to select the dropped frames smartly, selecting the best one to show for each vsync. Because of the timing features needed the drop functionality currently does not work if the correct-pts option is disabled. The code also adjusts frame timing slightly to avoid jitter. If you for example play 24 FPS video content on a 72 FPS display then normally a frame would be shown for 3 vsyncs, but if the frame times happen to fall near vsyncs and change between just before and just after then there could be frames alternating between 2 and 4 vsyncs. The code changes frame timing by up to one quarter vsync interval to avoid this. The above functionality depends on having reliable vsync timing information available. The display refresh rate is not directly provided by the VDPAU API. The current code uses information from the XF86VidMode extension if available; I'm not sure how common cases where that is inaccurate are. The refresh rate can be specified manually if necessary. After the changes in this commit MPlayer now always tries to keep one frame queued for future display using VDPAU's internal timing mechanism (however no more than 50 ms to the future). This should make video playback somewhat more robust against timing inaccuracies caused by system load.

CHECK_VDP_WARNING(vo, "Error when calling vdp_presentation_queue_display");
vo_vdpau: simplify time management and make it more robust vo_vdpau used a somewhat complicated and fragile mechanism to convert the vdpau time to internal mpv time. This was fragile as in it couldn't deal well with Mesa's (apparently) random timestamps, which can change the base offset in multiple situations. It can happen when moving the mpv window to a different screen, and somehow it also happens when pausing the player. It seems this mechanism to synchronize the vdpau time is not actually needed. There are only 2 places where sync_vdptime() is used (i.e. returning the current vdpau time interpolated by system time). The first call is for determining the PTS used to queue a frame. This also uses convert_to_vdptime(). It's easily replaced by querying the time directly, and adding the wait time to it (rel_pts_ns in the patch). The second call is pretty odd: it updates the vdpau time a second time in the same function. From what I can see, this can matter only if update_presentation_queue_status() is very slow. I'm not sure what to make out of this, because the call merely queries the presentation queue. Just assume it isn't slow, and that we don't have to update the time. Another potential issue with this is that we call VdpPresentationQueueGetTime() every frame now, instead of every 5 seconds and interpolating the other calls via system time. More over, this is per video frame (which can be portantially dropped, and not per actually displayed frame. Assume this doesn't matter. This simplifies the code, and should make it more robust on Mesa. But note that what Mesa does is obviously insane - this is one situation where you really need a stable time source. There are still plenty of race condition windows where things can go wrong, although this commit should drastically reduce the possibility of this. In my tests, everything worked well. But I have no access to a Mesa system with vdpau, so it needs testing by others. See github issues #520, #694, #695.

core/VO: Allow VO drivers to add/modify frames Add interfaces to allow VO drivers to add or remove frames from the video stream and to alter timestamps. Currently this functionality only works with in correct-pts mode. Use the new functionality in vo_vdpau to properly support frame-adding deinterlace modes. Frames added by the VDPAU deinterlacing code are now properly timed. Before every second frame was always shown immediately (probably next monitor refresh) after the previous one, even if you were watching things in slow motion, and framestepping didn't stop at them at all. When seeking the deinterlace algorithm is no longer fed a mix of frames from old and new positions. As a side effect of the changes a problem with resize events was also fixed. Resizing calls video_to_output_surface() to render the frame at the new resolution, but before this function also changed the list of history frames, so resizing could give an image different from the original one, and also corrupt next frames due to them seeing the wrong history. Now the function has no such side effects. There are more resize-related problems though that will be fixed in a later commit. The deint_mpi[] list of reserved frames is increased from 2 to 3 entries for reasons related to the above. Having 2 entries is enough when you initially get a new frame in draw_image() because then you'll have those two entries plus the new one for a total of 3 (the code relied on the oldest mpi implicitly staying reserved for the duration of the call even after usage count was decreased). However if you want to be able to reproduce the rendering outside draw_image(), relying on the explicitly reserved list only, then it needs to store 3 entries.

vdpau: split off decoder parts, use "new" libavcodec vdpau hwaccel API Move the decoder parts from vo_vdpau.c to a new file vdpau_old.c. This file is named so because because it's written against the "old" libavcodec vdpau pseudo-decoder (e.g. "h264_vdpau"). Add support for the "new" libavcodec vdpau support. This was recently added and replaces the "old" vdpau parts. (In fact, Libav is about to deprecate and remove the "old" API without deprecation grace period, so we have to support it now. Moreover, there will probably be no Libav release which supports both, so the transition is even less smooth than we could hope, and we have to support both the old and new API.) Whether the old or new API is used is checked by a configure test: if the new API is found, it is used, otherwise the old API is assumed. Some details might be handled differently. Especially display preemption is a bit problematic with the "new" libavcodec vdpau support: it wants to keep a pointer to a specific vdpau API function (which can be driver specific, because preemption might switch drivers). Also, surface IDs are now directly stored in AVFrames (and mp_images), so they can't be forced to VDP_INVALID_HANDLE on preemption. (This changes even with older libavcodec versions, because mp_image always uses the newer representation to make vo_vdpau.c simpler.) Decoder initialization in the new code tries to deal with codec profiles, while the old code always uses the highest profile per codec. Surface allocation changes. Since the decoder won't call config() in vo_vdpau.c on video size change anymore, we allow allocating surfaces of arbitrary size instead of locking it to what the VO was configured. The non-hwdec code also has slightly different allocation behavior now. Enabling the old vdpau special decoders via e.g. --vd=lavc:h264_vdpau doesn't work anymore (a warning suggesting the --hwdec option is printed instead).

core/VO: Allow VO drivers to add/modify frames Add interfaces to allow VO drivers to add or remove frames from the video stream and to alter timestamps. Currently this functionality only works with in correct-pts mode. Use the new functionality in vo_vdpau to properly support frame-adding deinterlace modes. Frames added by the VDPAU deinterlacing code are now properly timed. Before every second frame was always shown immediately (probably next monitor refresh) after the previous one, even if you were watching things in slow motion, and framestepping didn't stop at them at all. When seeking the deinterlace algorithm is no longer fed a mix of frames from old and new positions. As a side effect of the changes a problem with resize events was also fixed. Resizing calls video_to_output_surface() to render the frame at the new resolution, but before this function also changed the list of history frames, so resizing could give an image different from the original one, and also corrupt next frames due to them seeing the wrong history. Now the function has no such side effects. There are more resize-related problems though that will be fixed in a later commit. The deint_mpi[] list of reserved frames is increased from 2 to 3 entries for reasons related to the above. Having 2 entries is enough when you initially get a new frame in draw_image() because then you'll have those two entries plus the new one for a total of 3 (the code relied on the oldest mpi implicitly staying reserved for the duration of the call even after usage count was decreased). However if you want to be able to reproduce the rendering outside draw_image(), relying on the explicitly reserved list only, then it needs to store 3 entries.
