This removes a branch at a performance-sensitive point (in the middle
of the loop). In fate-swr-resample-s32p-8000-2626, this makes the code
about 10% faster. It also simplifies the loops, allowing us to rewrite
it in yasm at some later point.
The compensation_distance != 0 code and index < 0 code are still kind
of hairy. For compensation_distance != 0, this should likely be handled
in the caller, so that it calls swri_resample twice (once until the
dst_incr switch-point, and once with the remainder of the samples). For
index < 0, the code should probably be rewritten to break out of the
loop once sample_index >= 0, and then resume (e.g. as a tail-call) to
the common or linear resampling loops.

flvdec: Do not default to a video and audio stream
Merged-by: Michael Niedermayer <michaelni@gmx.at>
In the presence of no metadata, do not set any stream flag in the FLV
header but let the demuxer handle the detection and creation of streams
as data arrives.
Signed-off-by: Martin Storsjö <martin@martin.st>
If no streams were indicated in the FLV header, do not automatically
allocate by default a video and an audio stream. Instead, in the case
that the header did not indicate the presence of any data, allocate no
stream until data actually arrives for one type.

It is obviously nonsense since it produces wrong results
or even crashes (crashes should be encode-only though).
Fixes trac issue #1092.

The demuxer needs this value to generate correct timestamps in some corner cases
Ideally the parser would always set this correctly, but some parsers lac support
for extracting this value, also its not trivial.
This fixes a regression

The version check is changed so they are available with the current ABI
FFmpeg libs should have no problems with added fields, nor should any
application using the libs, and we regularly added fields in the past.
We also moved 2 of these fields to AVFrame already previously without issues.

The other format (full flac header blocks) should not be exported by any
demuxers anymore.
This allows to drop an avpriv_ function and also simplify the following
commits.
Some encoders (e.g. flac) need to send side data when there is no more
data to be output. This enables them to output a packet with no data in
it, only side data.
I do not know on which side to place the padding to encode with 16x16 MBs
If someone knows or has a known to be correct sample, please contact me
