The custom IO flag actually never is set for muxers, only for
demuxers, so the check was pointless (unless a user intentionally
would set the flag to signal using custom IO).

If one track doesn't have any samples within a moof, no traf/trun
is written for it. When the omit_tfhd_offset flag is set, none
of the tfhd atoms have any base_data_offset set, and the implicit
offset (end of previous track fragment data, or start of the moof
for the first trun) is used.

add support for AVC Intra 50 720p and 1080p without SPS/PPS header in mxf and mov demuxers. I got the SPS/PPS tables from libbmx.

__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.

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
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.

FooterPartition offset specified in RIP takes precedence over any value written
in PartitionPacks. This fixes the same issue f06f6da tries to fix without
introducing an extra variable.
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>
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.
