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.
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 <[email protected]>
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.
Hopefully will help in using some of its rather obscure features.

In a list of enabled fstypes, "none" now clears the list rather than
disabling all fstypes and interrupting the parser. To enable only one
(or more) fstypes, list the types to enable after "none".
For example:
"-fstype none" is the same as before: all disabled
"-fstype none,fullscreen" enables only the fullscreen type

Allows to use ITU-R BT.709 instead of the default ITU-R BT.601.

As part of merging subtitle-in-terminal changes make
update_subtitles() only clear existing subtitles if called with the
reset argument, and not try to set new ones. Later calls should set
the needed new subtitles, and this change avoids some problems with
trying to set subtitles when mp_property_sub() in command.c gets
called from initialization code before full initialization.
all other filters that should apply to it
(fix PEBCAK as seen on #mplayer)
