Hi! This may be off-topic because I don't know which tool is responsible for the problem but it may as well be mjpegtools.
I have a PAL VCD file like I have created with mjpegtools hundreds of times (I think) and burnt to VCD and played on my DVD player without any problems. Now, 352x288 and mpeg1 is an acceptable DVD format so I tried to convert it. After reading through this list and consulting several websites I came up with the following solution. A variant that handles SVCDs works perfectly and my DVD-players even swallows them without complaining. But this is about VCD. First demuxing. #tcextract -i 1.mpg -a0 -x mpeg2 > video1 #tcextract -i 1.mpg -a0 -x mp3 > audio1 First problem: (extract_mp3.c) missing start code at 0x1214 (extract_mp3.c) incorrect zero-byte padding detected - ignored Problem of tcextract or of the mjpegtools? Serious or ignorable? It has been suggested to covert audio to 48kHz: #mpg123 -w sound.wav audio1 #cat sound.wav | mp2enc -r 48000 -o audio1 No problem here Then muxing: #mplex -f 8 audio1 video1 -o movie1.out Again, no problem. The resulting file plays without problems. Then I start with the dvdauthor routine: #mkdir foobar #dvddirgen -o foobar #dvdauthor -o foobar --video=pal+4:3+352x288 movie1.out Here the serious problems start, I get a lot of the following error messages: WARN: unknown aspect ratio 8 Sometimes with the following variation: WARN: unknown aspect ratio 8CS, 0:00:00 When it comes to the actual building, error messages like the following pop up: WARN: audio sector out of range: -8203 (vobu #160, pts 16619) The resulting VOB starts playing but stops after less than half a second. For completeness sake, I finish the dvd-building with: #dvdauthor -o foobar -T #mkisofs -dvd-video -o dvd.iso foobar #cdrecord.sh dev=0,0,0 -eject dvd.iso So, there seems to be something seriously wrong with the audio on VCDs. It can't really be the Hz since SVCDs are not problematic at all. Should I reencode it in a different way or what?
