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

The check is meant for k8 CPUs. sad16_sse2 is ~20% faster than sad16_mmxext on k10.

the mpeg encoder would try to use them if vsad or vsse were selected for frame_skip_cmp
and frame_skip_threshold or frame_skip_factor were set to values != 0
example: "ffmpeg -i INPUT -c:v mpeg2video -skipcmp vsad -skip_threshold 1 -f null -"

rtpenc_chain: Don't copy the time base to the source stream by default
See: 1fe40e1b05
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Only copy it manually in the muxers where it makes sense (rtspenc,
sapenc). Don't touch the original AVStream in movenchint, where
the original AVStream should be kept untouched.
This fixes the normal tracks in RTP hinted files after
abb810db - the hint tracks were ok while the normal media tracks
were broken, noticed by Michael Niedermayer.
This reverts abb810db but achieves the same effect for the other
muxers.

It's needed for ff_svq1enc_init_x86() even if simd functions are disabled.
Alternatively, svq1enc_init.c could be made and the relevant code moved there.

Revert "rtpenc_chain: Don't copy the time_base back to the caller"
Merged-by: Michael Niedermayer <michaelni@gmx.at>
While it strictly isn't necessary to copy the time base (since
any use of it is scaled in ff_write_chained), it still is better
to signal the actual time base to the caller, avoiding one
unnecessary rescaling. This also lets the caller know what the
actual internal time base is, in case that is useful info
for some caller.
This reverts commit 397ffde115.
