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.

* cehoyos/master:
  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.

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.

Fixes ticket #3968.

This does not fix anything but gives users a chance to
know that they must not pass -sub_charenc UTF-16 to ffmpeg.

Fixes ticket #4059.

This makes FFmpeg's mp3 output more similar to lame's output.

FooterPartition offset specified in RIP takes precedence over any value written
in PartitionPacks. This fixes the same issue f06f6daa tries to fix without

This reverts commit 1c010fd0.
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

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.

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.

  vdpau/h264: request MAIN rather than BASELINE VDPAU profile for CBP
Merged-by: Michael Niedermayer <michaelni@gmx.at>

This is the same as the previous change, but for applications using the
old API (such as VLC 2.2).
Signed-off-by: Anton Khirnov <anton@khirnov.net>

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.
