libxvid is only an encoder, not a decoder and avconv is much stricter in the order of its options than ffmpeg. Putting -vcodec before -i means that you want to use libxvid as a decoder, which is not possible. $ avconv -codecs | grep libxvid avconv version 0.8.1, Copyright (c) 2000-2011 the Libav developers built on Mar 25 2012 16:52:16 with gcc 4.6.2 EV libxvid libxvidcore MPEG-4 part 2 If you want to encode with libxvid you should: $ avconv -i input.whatever -vcodec libxvid output.whatever
(In reply to comment #1) > $ avconv -i input.whatever -vcodec libxvid output.whatever the response is: Unknown encoder 'libxvid' so, same thing
