I'm trying to generate DVD-compatible MPEG2. I used these commands to create the video and audio streams:
mpeg2enc -v 0 -f 8 -b 9800 -F 4 -n n -o "test".m2v -q 7 -a 2 -I 1 -4 2 -2 1 -P mp2enc -v 0 -r 48000 -b 224 -s -o "test".mpa The generated files seem to be ok. In fact, the quality of the video stream is pretty good. Then i tried to mux them together, using this command: mplex -f 8 -o test.mpeg2 test.mpa test.m2v (i tried to add -V, but no change) But after a couple dozen megabytes, it failed. I included the warnings and errors at the end of this message. What could be the cause of it? What needs to be changed to avoid the error? The source is an amateur video, made with a DV camcorder, NTSC 29.9 fps interlaced, 720x480. It has lots of motion (camera sweeping left and right a lot), but doesn't have noise.
