6d702dc072 proresenc: force bitrate not to exceed given limit
Apple ProRes Format Specifications mentions target data size for every frame,
so make sure frame meets it. This also allows encoder to demand much smaller
packet sizes for output.

c742ab4e81 vc1parse: call vc1_init_common().
The parser uses VLC tables initialized in vc1_common_init(), therefore
we should call this function on parser init also.

9d3050d3e9 wma: don't return 0 on invalid packets.
Return 0 means "please return the same data again", i.e. it causes an
infinite loop. Instead, return an error.

41afac7f7a asf: prevent packet_size_left from going negative if hdrlen > pktlen.
This prevents failed assertions further down in the packet processing

74699ac8c8 mjpegb: don't return 0 at the end of frame decoding.
Return 0 indicates "please return the same data again", i.e. it causes
an infinite loop. Instead, return that we consumed the buffer if we
finished decoding succesfully, or return an error if an error occurred.

c7e8639c70 rtpdec: Identify incorrectly signalled H263
H263 in RTP can be packetized in two formats (RFC 2190, RFC
2429/4629). The former normally uses the static payload type 34,
while the latter normally uses dynamic payload types with the
SDP format names H263-1998 or H263-2000.

Look for packets that don't look like proper RFC 2190 packets and
switch to depacketizing them according to the new format if they
match some heuristic criteria.

WMApro actually support 13-bits block sizes (potentially even up to 14),
and thus we should support that also. If we get block sizes beyond what
the decoder can handle (14 is possible depending on s->decode_flags),
error out instead of crashing.

c9fdf3241a bethsoftvid: synchronize video timestamps with audio sample rate
According to unofficial documentation, the video rate is locked to the audio
sample rate. This results in proper synchronization of audio and video
timestamps from the demuxer. This only works if the first audio packet occurs
before the first video packet or the audio sample rate is the default rate of
11111 Hz, both of which are true for all samples in our archive.
