I've seen screenshots of video compressed with mp1e, and it was very nice.
Much better than same scene with ffmpeg.

I couldn't get it producing audio, maybe problem wiht sound drivers
(sblive/oss) or mixer.

unfortunatelly this project seems to be dead :(
i send a mail to Gerard (author) 2 weeks ago, but no answer yet.
even no new (pre)releases from march.

Ehh. The it's usefull only for middle stage between capturing and final
compression. Is it realtime?

Yes, why not. Can you add it?
