Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.
If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().
At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.
Should address trac ticket #2672.
SDL surface pitch is 16bit, to avoid possible overflows, we limit the window
width to 16383. Fixes ticket #2428.

Showing A-V diff has no use if there is no audio and video stream, but showing
the audio or video clock difference to the master clock can be useful.

It was raised to 4 because of a theoretical issue, if we ensure that we do not
return from the display function without popping one picture from the queue,
then its OK to use the old size.

The corresponding codec options (skip_loop, skip_idct, skip_frame) can be
set in a more flexible way.
This technically causes a user interface break, but since the options
were not even documented and we just released a major version that should
not be a serious issue.

We are now using a pts based approach, libavutil/libavcodec should provide the
correct pts-es anyway. This also fixes an issue when seeking to a frame with a
pts set to zero.
Signed-off-by: Marton Balint <cus@passwd.hu>
We use a refresh loop which displays the frames and also does the polling for
pending events in a non-blocking way. If we know the required delay until the
next frame, then exactly that amount of sleeping will be done. After each
handled event we check if we have to display a frame which kind of makes
displaying the frame a high priority event.
This improves greatly the smoothness of the video output especially with 50fps
content.

Actually we just re-create the filters, since there is no way to flush them.
Fixes hangup with yadif filter on seeking forward caused by a filtered frame

Signed-off-by: Marton Balint <cus@passwd.hu>
Previously VideoPicture->skip was used for that, using videoq.serial enables us
to detect obsolete frames right after pushing flush_pkt to the packet queue, so
we don't have to wait for the decoder thread to pop the flush packet anymore.
This is good because until now a full video picture queue may have blocked the
decoder thread.

"que" sounds like a slang word to me. This commit renames a few
variables, fix the comments and the logging messages (sometimes along
with small other typo fixes).
If the XV image linesize was different from the width, SDL would create an
overlay wider than the actually requested one. This causes a greenish line on
the right, because the rightmost texel is blended with unset data. This patch
introduces a function which duplicates the rightmost texel to the unset space,
that way the blending will be done with duplicated border texels.

Set codec id in case another codec is forced on the context (e.g. when
the user specify the codec with -codec).
For example fix:
ffplay -vcodec pgmyuv -i "tests/vsynth1/%02d.pgm"
Fail with a meaningfull error message in case of bogus input.
Also the new options are more consistent with the rest of the tool
options, since it does not support generic stream specifiers.

In timestamp based seeking we update the external clock to the seek target,
therefore we should use sane timestamps even if libavformat could handle

The real av_sync_type may be different to VideoState->av_sync_type, because the

We now initalize the external clock to 0 and, we use the system clock to

When the audio queue was empty, it was not filled until the 10ms delay expired
in the read thread. This patch changes the delay method with a condition wait,
which reacts to an empty queue a lot faster, therefore the audio buffer
