Since MonoTorrent is quite features complete. I look for new challenge ;)
So I have start to work on dirac but I skip it quickly because we have first to work on a more flexible system in for media stream source in moonlight.
I have start to code something where I get out of ogg media stream source the vorbis code and try to make ogg accept other codec as dirac or theora.
I come to conclusion that before done glue I need to have more codec to see all the needs of differents codecs. So I start to code a theora decoder from specification of xiph.
If you want to help, I code on my own branch here:
Anyway, it is just a start so do not expect to read a single video, it need a lot of work to achieve it!
