If there ost->picref is NULL, it will likely crash anyway a few lines
below by dereferencing it in order to access video attribute.

filtered_frame is overwritten just below anyway.

They were introduced in an earlier commit that introduced use of named
arguments. One cause was a typo, a second cause appears to be a bug in
x264asm that I work around by not using named arguments.

If muxing into mpegts, 4 byte startcodes for the first NAL
of an access unit is required. Thus it is simplest for the
RTP depacketizer to just use 4 byte startcodes everywhere.

Seek beyond the end will now directly return an error instead
of claiming to succeed and then return EOF immediately on next read.
This change is because before 47e015e6
mkv seek incorrectly never failed.

In particular, detect when the index is obviously broken.
This fixes the worst symptoms of trac issue #958 and makes
sense to allow seeking in files without index.
However it is possible that there still is an index parsing bug
with that file.

This avoids unused variable warnings when zlib/bzlib are not available.

This allows dropping the av_unused argument from them.

Recent versions of gcc (4.4+) no longer give false positive warnings.

When segmenting the output from the mpegts muxer, one can
now set this option when cutting to a new segment, to make sure
the next segment starts with PAT/PMT/SDT.

This allows removing any gray16-specific code, which is essentially
identical to the per-plane code in yuv2plane*().

Also give a more suitable name to the MMI-optimized IDCT;
it is not PS2-specific, as the name currently suggests.

This fixes compilation with -Werror=missing-prototypes.

* qatar/master:
  swscale: convert yuv2yuvX() to using named arguments.
  swscale: rename "dstw" to "w" to prevent name collisions.
  swscale: use named registers in yuv2yuv1_plane() place.
  lavf: fix aspect ratio mismatch message.
  avconv: set AVFormatContext.duration from '-t'

The cleanup is only done now when
a picture is returned (assuming that it has to be done when its returned)
a error is returned (assuming that there will be no further progress on the frame)
the codec is not h264 (this is still needed due to some deadlocks in realvideo)

This fixes a decoding regression with 00017.MTS

To make seeking work correctly, we must write a new granule for
each keyframe.
Unfortunately we currently have no regression tests due to no
included Theora encoder.
A test based on -vcodec copy from a Theora FATE sample should
probably be added.
