[MPlayer-users] Can mencoder write partial files while encoding?

For that you'd have to use transcode with v4l import. BUT transcode
(like ffmpeg, btw) doesn't keep track of a/v as well as mencoder. If the
input process misses a frame (which may happen easily under moderate
load) no frames are duplicated or anything like that, so you'll end up
with an out-of-sync movie. First minute is ok, then it starts showing.

I have no solution for this, maybe I'll have a look at the v4l import
module and try to fix it. Don't hold your breath though.

OTOH IMHO transcode is actually being worked at, at the moment, contrary
to mencoder :-(

Sorry for being OT.
