Tvheadend

I've been tooling around trying to get on-the-fly AC3 transcoding into tvheadend, so that a raspberry-pi client would be able to bitstream instead of struggling to decode HE-AAC that it then has to downmix to stereo anyway. I tried altering transcoding.c to allow use of the ac3 encoder, and that works in as much as it'll plug into libav and ask it to transcode to ac3...

The problem I've hit up against is that libav 8 has known bugs that causes crashes in AC3 transcoding that mean it's only possible to transcode to stereo AC3 not 5.1, which defeats the point.

Will the dependency on the old version of libav 8 be lifted?
