Then why *does* it try to seek? I use stdin with raw dv video (captured
right from the camera) and it says "seek failed". Why seek anyway?

(This is one case where I can't use transcode, because mencoder, when
tried on files, gives me enough performance for realtime - and transcode
does not. I'm nearly sure transcode won't have this problem, because it
uses fifos internally; but the fifos may be causing the lower
performance. As for ffmpeg binaries, I can't use it because they just
segfault on me, and the ffmpeg-devel list is silent).
