There is nothing we use of the latest version, downgrade version number
to increase decoding support.

Based on this comment by vel2000:
http://ffmpeg.org/trac/ffmpeg/ticket/1642#comment:17

In avfilter_config_links(), if the current channel layout is not
specified, set the same value of the previous link in the filterchain.

Consistent with the logic used to set the other link parameters.

yasm generates a warning instead of an error when "CPU amdnop" is not supported, so the check always succeeds.

HAVE_CPUNOP as true when the available yasm version doesn't support amdnop doesn't make sense.
Check http://fate.ffmpeg.org/log.cgi?time=20120901143315&log=compile&slot=x86_64-archlinux-gcc-oldyasm to see the amount of warnings it generates.

This fixes stream lookup in flv demuxer. When used with librtmp
protocol streams are sometimes added after head arrived. If the
first stream added in flv header reader is Audio stream then it
is messed with Video stream added later in the code patched.
The result is I have 2 Audio streams (first of them is said to have
a video codec like h264) instead of Audio/Video pair.

If the header is invalid, there is no need to get at buffer.
Do it after the header has been checked.

With this change avconv compiled against libav and linked to ffmpegs libs
will run through the whole fate testsuite without any crashes.
857 tests pass, the remaining tests fail one way or another, which is
to be expected as avconv is not a drop in replacement for ffmpeg
The testsuite used was the ffmpeg fate testsuite, not libavs.

After much discussion and back-and-forth, we reached the conclusion
that matroska uses convergence_duration for subtitle duration because
a 32bit value isn't large enough to store the duration if sub-micro-second
timebases are used. Matroska may not be the only one that supports these
timebases, but it's certainly the only one that ffmpeg attempts to support
in this way.

The long term solution that we seemed to reach was that if we encounter
a matroska file with a sub-micro-second timebase, we should internally
scale it up to at least micro-second, and then duration can be used
normally. This suggests that on the encode side, we should not allow
generation of files with sub-micro-second timebases, but that's a separate
issue.

That being a non-trivial change, and the subtitle interoperability breakage
being very real, I'm re-submitting this small change for consideration.

In this diff, we make sure that duration is populated by the matroska
demuxer, and that convergence_duration is respected in matroskaenc and
srtenc, but that duration is used otherwise. This ends up being a strict
improvement - pipelines that use convergence duration are unchanged, and
ones that are currently broken due to the duration mismatch will start
working - except for the ones with the extreme timebases, but those were
already broken.
