Applications can use this to silence the message.

__sync built-ins are considered legacy and will be deprecated.
These new memory model aware built-ins have been available since GCC 4.7.0

Use them by default when available except for __atomic_compare_exchange_n(),
which is slower, and is instead implemented as a fallback for when and if gcc
removes the legacy __sync built-ins.

No need to keep the old symbols around until a major bump since lavd functions
with the avpriv_ prefix were never exposed.

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.

The fieldmatch filter has no problem with mixed telecined and

  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.

This does not fix anything but gives users a chance to

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

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.
