931da6a5e9 lavd/v4l2: don't use avpriv_ prefix for internal functions
No need to keep the old symbols around until a major bump since lavd functions
with the avpriv_ prefix were never exposed.

2114e88432 avformat/mxfenc: AVC Intra support
To keep h264 parsing simple and fast, I used the framesize for selecting the right Panasonic codec label. The framesize is fixed for Panasonic AVC Intra.

This patch only supports AVCI50/100. But in all flavours, i.e. with no SPS/PPS in header.

fd1652b3ba Improve the fieldmatch documentation about mixed telecined content.
The fieldmatch filter has no problem with mixed telecined and
progressive content but the decimate filter does not detect the
changing framerate and drops progressive frames.

  Mention in the documentation that fieldmatch needs cfr input.
  Use v4l2 input format automatically if filename starts with "/dev/video"
  Print a warning if a subtitle demuxer changes utf16 to utf8.
  Do not set the lame quality if the user didn't request it.

238ed47fae Mention in the documentation that fieldmatch needs cfr input.
This can be improved in the decimate filter but for the moment
explicitely mentioning that mixed telecined and progressive
content is unsupported is an improvement.

37c3686155 mxfdec: Parse PreviousPartition in mxf_seek_to_previous_partition()
Without this patch the demuxer can get stuck in a loop if PreviousPartition
points somewhere where there's no PartitionPack, or if klv_read_packet() syncs
back up to the current partition.

This should fix Ticket3278 properly and unbreak Ticket4040.

f1c21a200b avformat/mvdec: Check size in read_table() for validity
This check is redundant with the previous commit but it provides
better error messages and feedback while the previous commit
ensures that var_read_string() doesnt return uninitialized arrays
if it itself is feeded with an invalid size possibly through a
different future codepath.

26ab504ad8 vdpau/h264: request MAIN rather than BASELINE VDPAU profile for CBP
The H.264 Constrained Baseline Profile (CBP) is a subset of both the
Main Profile and the Baseline Profile. In principles, a hardware
decoder that supports either of those can decode CBP content. As it
happens, Main is supported by all VDPAU drivers, and Baseline is not.

So favor map CBP to MP for now. Hopefully in the future libvdpau will
offer an explicit choice for CBP.

This fixes bug 757.

090c67d586 matroskaenc: write correct Display{Width, Height} in stereo encoding
should be the raw amount of pixels (for example 3840x1080 for full HD side by
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
one plane (1920x1080 for that full HD stream)."

So, move the aspect ratio check in the mkv_write_stereo_mode() function
and always write the embl when stereo format and/or aspect ration is set.
Also add a few comments to that function.
