Add a mode where libavcodec's reordered_opaque feature is used to
associate container packet timestamps with decoded frames. This should
improve behavior at least for MPEG files with interlaced h264; the
previous code does not cope well with the libavformat demuxer
producing two field packets with separate timestamps but the
libavcodec h264 decoder only producing a single output frame for those
two packets (so half the timestamps have no associated output frame).
The current libavformat mpeg demuxer seems to finally work with
interlaced h264 files and produce valid timestamps which are useful
with a mode like this.
By default MPlayer now selects between this new mode and the old one
automatically based on the number of timestamp problems they cause; by
default the new mode is used if both seem to work. The new option
-pts-association-mode can be used to force a particular mode. If
correct-pts mode is disabled this has no effect on timing.
Also remove the "EXPERIMENTAL" marker from the manpage description of
-correct-pts.
By default (without -nokeepaspect) MPlayer tries to maintain video
aspect ratio by using window manager hints to keep output window
aspect when resizing. Before this commit it would however scale the
video to completely fill the window even if the window manager did not
respect those hints. Change the behavior to add black bars like in
fullscreen mode instead in this case.
Check the return value when setting any video mixer attribute and
print an error message if the operation failed. Also simplify code by
changing update_csc_matrix() to use the utility function added for
this.
Remove the help text explaining -vo vdpau suboptions that was printed
in case of parsing errors. It did perhaps have some value, but there
are also reasons to remove it: it was printed in an ugly manner in the
middle of output, most other MPlayer options do not have such internal
help texts either, and it was detailed enough that it required
maintaining documentation about the options in two separate places
(the man page and the help message).
Part of the code is currently under #ifdef to allow compilation with
older VDPAU library versions; that can be removed later.
Partially based on a patch by Carl Eugen Hoyos.
Add a property to select YUV colorspace. Currently implemented only in
vo_vdpau and vo_xv. Allows switching between BT.601, BT.709 and
SMPTE-240M (vdpau only).
The xv support uses the "XV_ITURBT_709" attribute. At least my NVIDIA
card supports that; I don't know whether other xv implementations do.
Bind the colorspace switch to the 'c' key by default. 'c' is currently
used by vo_sdl for some fullscreen mode change thing, but at the moment
that does not conflict and if it will in the future then vo_sdl can
change.
VDPAU part based on a patch from Lauri Mylläri <lauri.myllari@gmail.com>
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.
Clean up code related to frame buffering and generate pts information
also for the next frame in the output queue. The timing information
will be used in a following framedrop patch.
This commit adds one frame of buffering delay in vo_vdpau and
increases the number of buffered vdpau video surfaces from 3 to 4. The
delay increase makes it more important to fix remaining code in
MPlayer that doesn't deal well with filter/VO delay; OTOH it should
help any decoding/filtering parallelism in the underlying VDPAU
implementation as now filtering a frame for display can happen while
the next one is being decoded.
Make audio uninit consistent with e.g. the demuxer uninit code and
also avoids a possible crash.

This makes -slang work when used with menu navigation or in general
when the subtitle is not available for parts of the playback or the
subtitle stream ID changes during playback.

Otherwise it would just hang, either at the menu or trying to play the
last played frame as a still frame.
