in src/add-ons/media/plugins/avcodec here is a modified version of
my FFDecoder plugin for R5, which uses ffmpeg's libavcodec.
ffmpeg can use several libraries by itself to decode even more
things...
including AAC, FLAC I think, ...
HuffYUV is handled by libavcoded.
I might add several file readers as well...
DVD: don't have any DVD here, but I'm sure someone will anyway.
MP4: it's nearly Quicktime. I've already written a mov parser,
so I'll do that one.
Besides I'm adding an nsv demuxer to ffmpeg before doing one for Haiku.

ffmpeg itself has a --risky switch on configure to include them...
Just do your job lobbying the EU commission so they don't vote software
patents and we are safe. Oh, right some ppl live in the US...
I guess they should migrate to Canada. With Bush2 there is a new
campaign

Why not ? :)
I patched nplay recently to do just that.

That's called progressive download, and it's not that difficult to do,
even with AVI.
