Right, but the interlaced stream can contain progressive material.

MPlayer outputs to a file or a named pipe, not to stdout.

If it's from a DVD it is interlaced. The DVD specs do not allow
progressive streams.

Hi again,
As yuvscaler gives me errors when I use MPlayer to decode the stream (I
checked the output of MPlayer and I don't detect any problem. All frames have
the right size - w*h*1.5 - and start by FRAME\n), I tried using transcode
only to decode the input.
I tried the following, which seems

Yes, that's what I found out too. Transcode can handle vob input if you
specify -x vob,null. I was trying with -x mpeg

Is that valid ? Note that I don't get the error on the first frame, but on
frame 15:

Oh. Ok - but now you know another approach for the next time ;)

To make things even easier, I only have a partial dump (the main title), so
there's no VIDEO_TS.IFO file (there's a VTS_03_0.IFO though), and MPlayer
complains about not being able to ope

Hi everybody,
I'm trying to transcode a DVD to SVCD. The usual approach is, I think, to use
mplayer or transcode to read from the DVD and output to a named pipe, and cat
the pipe to yuvscaler and mpeg2enc.
This, however, becomes a bit more complicated as the material I'm trying to
convert is a
