But today...<br /><br />I'm getting the error message:<br />$ protocol not found<br /><br />- both when I use mp3 and libmp3lame as the codec. This may have something to do with the new linux kernel 3.8.1 that I installed this morning, but that's a stretch, I think.Joehttps://www.blogger.com/profile/10080690295987218010noreply@blogger.comtag:blogger.com,1999:blog-6006114617625504970.post-17439137702037647172012-11-23T04:53:48.594-05:002012-11-23T04:53:48.594-05:00ffmpeg -i input.mkv -acodec copy output.m4a wouldn...ffmpeg -i input.mkv -acodec copy output.m4a wouldn't re-encode the audio (if it was AAC).
