First, sorry for the previous, subjectless message; and sorry if people received my *second* attempt at sending this message as well. I've been having mail difficulties because, among other reasons, my ISP decided all of a sudden to block outgoing SMTP. Also, sourceforge seems to have been acting oddly. Is it possible to the new mpeg2video libavcodec codec to create an mpeg2 stream that can be used to author a dvd? If so, what limitations must be placed on the stream? I attempted to use a method similar to what was described in the post about SVCD creation to restrict the bitrate so mplex wouldn't complain, but my dvd player only got a black screen (the timer advanced and the audio played fine, though). I suspect the problem may partly lie with my keyframe interval, but I couldn't find the correct value (I used the value that the man page listed as the maximum for strict mpeg 1/2/4 compliance). Also note that I made the modification suggested by the person who made the SVCD creation post to not get the spurious bits in the dumped mpeg stream (is this really necessary?) and this is why the first sox invocation is necessary (this could be done in one command, yes..). One other thing I changed was to use add the -V flag to mplex (I'd try making another but my dvd-player doesn't support rewritable discs and I'm loath to keep making toasters. mencoder -o test.avi in.avi -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=2500:vhq=1:vrc_eq=isI*200000+isP*75000\ :vratetol=1000000:aspect=4/3:mbd=1:keyint=132 -oac pcm -vf pp=de\ ,denoise3d=4:4:5,scale=720:576 -sws 9 mplayer -dumpvideo -dumpfile test.m2v test.avi mplayer -dumpaudio -dumpfile test.pcm test.avi sox -t raw -c 2 -w -s -r 44100 test.pcm -t raw -c 2 -w -s -r 44098 \ test.pcm2 rate sox -t raw -c 2 -w -s -r 44100 test.pcm2 -t raw -c 2 -w -s -r 48000 \ test.pcm3 rate toolame -s 48 test.pcm3 test.mp2 mplex -V -f 8 -o test.mpg test.m2v test.mp2 dvdauthor -o dvd/ --video=ntsc+4:3+720x576 test.mpg dvdauthor -T -o dvd/ Joshua Rothenberg adonna@myrealbox.com
