Problem with libavresample is that it'll land in libav master, and will
probably be available with next major libav release. The one that will
come with libavcodec/format 54, effectively delaying its wide adoption.

OTOH, there's the not so perfect libswresample, which still
does what its asked to do and has been available for 6 months in
ffmpeg master, and since ffmpeg 0.9.

Its not my call, but IMHO its not a good reason to wait, and once
libavresample will be available, it shouldnt be too hard to convert it
or create a new plugin.
