The stream can be specified as "#129" or "#0x81".
It is especially useful for VOBs dumped from a DVD,
where the language-id mapping is available externally
and the probing can find the streams in a random order.

This fixes the warning:
cmdutils.c:897: warning: ‘type’ may be used uninitialized in this function

Also add the public interface libavfilter/buffersink.h.

Based on a commit by Stefano Sabatini.

This way we don't require a clearly defined corresponding input stream.

The result for the xwd test changes because rgb24 is now chosen instead
of bgra.

The preset files have been renamed some time ago.

Note, this doesnt break compatibility with libav, as libav
has implemented a incompatible and more limited system under the same
-cpuflags command line option we used since some time.

The differences to libav for example are we can do things like
ffmpeg -cpuflags -sse+mmx -cpuflags +3dnow
Its also possible in our system to force flags that have not been
detected as available
And our -cpuflags works with all tools not just 1

Useful for testing.

Fixes listing encoders.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

This allows globally forcing specific cpuflags (or lack thereof)
Useful for debugging and benchmarking

The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.

This partly reverts 1c5e9551bca12e040270e0cd3d71440f83e9f8ae,
a change of behaviour that was not discussed.

The reason for the revert is that FFmpeg cares about bugreports.

This way, all messages can be easily disabled with -loglevel.

Behavior change -- configuration is printed with AV_LOG_VERBOSE, so it's
not shown by default.

This way it can be applied to cmdutils too -- e.g. showing the banner
and printing startup messages.
