In theory this should have worked (though a 100MB file sounds way too
small). However, I've never tested it, so I can't say. on my 1.6GHz
box, I can transcode at ~1:1.2 realtime from rtjpeg to mpeg4 9so it takes
about 1:20 to encode 1hr of video. That is without reencoding the audio.
So I dunno what kind of box you are running on, as to whether 4hrs for
4GB is reasonable or not. I have a PVR250 sitting here to test the
transcoder with, but I haven't gotten around to installing it yet. Note
that mythtranscode produces an nuv file, so it will only work with a
patched mencoder. Also, the method of dealing with cutlists isn't
supported by the mencoder patch as far as I know, so ~1sec around cuts
may look pretty nappy.
