Thats for getting off youtube, but the stuff I have already (and sometimes youtube has deleted) I already use ffmpeg to encode it so ... ffmpeg -f flv -i "$TITLE.flv" -f avi -vcodec mpeg4 -b 800k -g 300 -bf 2 -acodec mp3 -ab 128 "$TITLE.avi" (thats all one line - mail program has word wrapped it) is a snippet from my fetch script. So I now have an avi with mpeg4 and mp3 streams in them. This, when loaded in cinelerra only shows the audio. So now I tried ffmpeg -i $TITLE.avi -acodec ac3 -vcodec mpeg4 -y $TITLE.mov and I (I think) get the same file your comand gives. And I get a resource in which cinelerra sees both some video and audio. However if I load that file into the timeline I see it all - but "playing" shows the video and no sound. What I then did was load both the avi and mov resources, and put them on the timeline by removing the mov sound and replacing it with the avi sound. The combination gives me my stuff back. > > or, failing that: > > ffmpeg -i youtube.flv -acodec ac3 -vodec mpeg2video -y video.mpg This fails when converting from my .avi file rather than the .flv source -- Alan Chandler http://www.chandlerfamily.org.uk _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
