mpeg2enc doesn't seem to work correctly when I use the -M option for multi-cpu encoding.
I tired encoding a stream with these options: -f 5 -B 299 -S 700 -K kvcd -a 2 -p -g 6 -G 25 -b 2500 -q 3 --dualprime-mpeg2 and then the same exact options with -M 2 added. Without -M 2, mpeg2enc generates a stream of about 550 MB that mplex (with options -f 5 -r 0 -V) will accept without trouble. I can create a svcd with vcdimager and watch it on my DVD player with no problems. With -M 2, mpeg2enc doesn't have any trouble generate a mpeg2 stream. However, when I try to mplex it, mplex complains there are multiple sequences, and I need to put a %d in the filename: INFO: [lt-mplex] Scanned to end AU 1 ++ WARN: [lt-mplex] No seq. header starting new sequence after seq. end! INFO: [lt-mplex] Scanned to end AU 5 ++ WARN: [lt-mplex] No seq. header starting new sequence after seq. end!

I also get many buffer overflow errors, and the stream won't multiplex. If I try to make a svcd, it skips like crazy on my dvd player. Again, if I do everything exactly the same but omit the -M 2 flag, everything works fine, but my CPUs are less utilized. ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
