I believe any task related to audio and/or filtering is fine.

As for the mentorship, I'm not the most qualified person here for what
regards the audio part, but I'll try to act as mentor if no-one else
will step for that (Vitor?) iff there is agreement on that, otherwise
I'll gladly co-mentor.

I've not a strong opinion on this, but there are very intersting
libraries (e.g. libopencv, libaa, or think at libfestival or libsphynx
for audio) which would make sense to hookup in libavfilter without to
replicate all the functionality in FFmpeg, that would be out of
scope.

As for the qualification task, in the case people don't like the
vf_imlib2 port, I suggest a deinterlace/interlace filter which seems
needed for video filters integration in ffmpeg, I believe there is
something in MPlayer/libmpcodecs which can be used as reference, but
as I said anything related to audio/filtering should be OK for showing
us if you seem able to accomplish the GSoC task.

Good luck!, regards.
