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 to do the trick: transcode -i /path/to/dvd/dump/ -x vob,null -y yuv4mpeg,null -o stream.yuv When using the vob import filter, transcode invokes tccat internally which is able to read from a DVD dump. However, there was still a little problem: the yuv output was upside down. Using -z, as suggested on the transcode mailing list, mirrored the picture horizontaly which fixed the problem. I'm still a bit confused about why the picture is upside down without -z. Probably a bug in transcode. Using the -V (YV12 as the internal format) also fixes the horizontal mirror problem (which probably means that the yuv4mpeg output in transcode is faulty when using RGB as the internal format). I thought it would give better performance (converting from YUV to RGB and back is a waste of CPU time), but it somehow inverts the U and V components. I'll try the latest transcode from CVS sometimes to see if that was fixed. If not, it should be pretty straightforward.
