The problem is still present with r29747. Again, -demuxer lavf is the magic thing. Uploading a sample makes no sense, as the problem shows up on many files with different containers/codecs. The mencoder line is like the one in my first email, there is just '-oac mp3lame -lameopts q=9' replaced with '-oac lavc -lavcopts acodec=ac3:abitrate=128'. But I would like to know which is broken, the generated avi file, or the AVI demuxer. As I target to backup the transcoded files. I can give other information as needed. Regards
