I've on occasion needed to re-encode the audio stream on a video file, for example when I've received DVB files which have incorrectly encoded audio (maybe just an audio glitch on a DVB transmission, different languages on right-left instead of on different tracks etc.)
Back in pre-history I used to do video/audio stream demux, then % transcode -i stream.mp2 -x null,mp3 -n0x50 -y mp2enc -o stream-reencoded and then remux the video/audio stream back together. I came to think that it should be doable just with transcode (input whole mpeg file, write the raw video stream to new a file, re-encode the audio stream) and then mplex the separated video/audio streams back together. However, I don't seem to be able to get the right combination of input/output "raw" filters because I keep getting a huge YUV RIFF file as the video. When I just want to copy the mpeg video stream through unmolested, what's wrong with the following command line? % transcode -i stream.mpg -x mpeg2,mp3 -y raw,mp2enc -ext .m2v,.mp2 -o stream-reencoded Also, wasn't there a mechanism to call a multiplexer directly from transcode with the video/audio streams on named pipes, I couldn't locate info on the Wiki? -- /* * * Otto J.
