What I did to reproduce: - I've updated transcode to 1.1.0-RC2 - I've taken a bunch of sample png files, and I've converted them to a pvn file using the following procedure: -- converted each one to pnm using ImageMagick's `convert' tool (convert file.png file.pnm) -- converted the PNMs to a single pvn using pnm2pvn (./pnm2pvn test.pvn *.pnm) pnm2pvn compiled in situ and downloaded from: wget -v http://www.cse.yorku.ca/~jgryn/research/pvn/pvn20080605.zip [so I'm assuming it is good :)]) - transcoded with tc using the commandline you've provided above Everything looks good on mplayer here, except for an annoying bgr/rgb swapping (blue faces), but that's not the core problem. My box: intel core2 q9300, debian testing amd64, gcc 4.3.2 I don't have any window box handy to play with. I'll try ASAP.
