Install ffmpeg back to Ubuntu. That's what I did. -nitrolinux Sent via the Samsung GALAXY S® 5, an AT&T 4G LTE smartphone -------- Original message -------- From: [email protected] Date:10/03/2014 4:46 PM (GMT-06:00) To: [email protected] Cc: Subject: [libav-tools] (no subject) Hi. I am trying to figure out how to do something in avconv that I could do in ffmpeg. Apparently the syntax has changed or something, but anyway, what I am trying to do is take a program recorded using a satellite receiver that is saved to a .ts file and convert the audio to 5.1. The video is fine as is, but the audio is sent in three separate streams (there are actually more bout the sic channels needed for 5.1 are in the first three)/ Each stream contains two channels of audio and they are arranged as follows: First stream: Left and Right channels Second stream: Center and LFE channels Third stream: Left surround and Right surround channels. Now in ffmpeg on my OS X box I can do this to convert the file to normal 5.1: ffmpeg -i "original program.ts" -c:v copy -filter_complex '[0:1][0:2][0:3]amerge=inputs=3,pan=5.1:FL=c0:FR=c1:FC=c2:LFE=c3:BL=c4:BR=c5' -c:a mp2 "converted program.ts" However, on my Ubuntu system it appears that ffmpeg has been replaced by avconv and if I try essentially the same syntax, simply substituting avconv for ffmpeg in the line above, I get this error: Unrecognized option 'filter_complex' Failed to set value '[0:1][0:2][0:3]amerge=inputs=3,pan=5.1:FL=c0:FR=c1:FC=c2:LFE=c3:BL=c4:BR=c5' for option 'filter_complex' I'm guessing there must be some way to do this in avconf but I have no idea what needs to be changed to make it work. Does anyone know how to accomplish this? _______________________________________________ libav-tools mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-tools
