[Mjpeg-users] problem with mpeg2enc and -M option
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!

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.

There was a subtle unitialized variable use that could cause the sequence end flag to be erroneously set. If a cvs update and rebuild doesn't fix the problem then it's back to the drawing board ;( Cheers, Steven Schultz --- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

I had to do make clean after the cvs update, or mpeg2enc would crash. It seems the Makefile is missing some dependencies, but since it's autohell I have no idea how to fix it. --- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

Re: [Mjpeg-users] problem with mpeg2enc while using transcode.
On Wed, 7 Jan 2004, Nathan Morell wrote: The rest of your suggestions worked just fine! I removed the k option, and played around with the aspect [it was also screwey] and Great! It would appear that when exporting to mpeg2enc that transcode is already swapping the U and V planes into the correct order so giving a -k undid that and caused YV12 instead of 4:2:0p to be given to the encoder. everything is working fine except for the Audio now. I'll append a complete output from Mplayer and Transcode; otherwise, could you tell me This is wandering a bit away from mjpegtools but I think I have a method that will work to get the audio. If mplayer can play the input avi file then mplayer -dumpfile output.wav -dumpaudio input.avi mp2enc -b 128 -o output.mp2 output.wav should do the trick. Then use mplex to put the .m2v and .mp2 files together. Cheers, Steven Schultz --- This SF.net email is sponsored by: Perforce Software.

[Mjpeg-users] problem with mpeg2enc while using transcode.
I posted this problem to the transcode list and they said it was a problem with the mjpeg tools. They also mentioned that the SuSe package for mjpeg tools was fubared.

Re: [Mjpeg-users] Problem with mpeg2enc
$ cat result3.yuv | mpeg2enc -v -o result3.m1v **ERROR: [mpeg2enc] Could not read YUV4MPEG2 header: bad header magic! Have you tried running that in gdb, so you can find out where is really crashes. But I guess that the problem is not really in mpeg2enc. The -v to mpeg2enc requires a numeric argument --- that weird bad header magic error is because the argument was missing. (Thus, the -o was interpreted as the arg to -v, and then result3.m1v was interpreted as the *input* file --- which was certainly not a YUV4MPEG2 stream, even if it did exist.) (This doesn't explain the original problem, but maybe the debugging will be a little more productive.) -matt m. --- This SF.net email is sponsored by: SF.net Giveback Program.

Ok, I will try also there, but the problem appears only using mpeg2enc If you want information how to create a mpeg stream you can take a look that the mjpeg howto. I,ve already read that; what I need is either the specifications of the mpeg file format (I guess they're not free, isn't it?) or a tool to debug the header's fields and the frame order, or wathever else. I have two mpeg files, one working, made with the transcode built in encoder, while the other not (made with mpeg2enc), of the same piece of movie. Looking on the files they differ in some places (beginning at hex 1240 in the files) but I don't know the meaning of this. The file headers should be identical. Does vcdimager produce a differnet output ? I don't tested it, but I think so since also the mpeg are different. Thank you again for any information, especially about the mpeg file format.
