So in the end it is still probably better to use the -32 without the k :-) But anyway this does not explain why it worked for me and not for Peter. Mine is the latest update from the repository. I cannot see much difference between his version of ffmpeg and mine, which is a Packman built with all Packman libs : orion:~/tmp > rpm -qi ffmpeg-0.5.21861svn-0.pm.1.4.x86_64 Name : ffmpeg Relocations: (not relocatable) Version : 0.5.21861svn Vendor: http://packman.links2linux.de Release : 0.pm.1.4 Build Date: Tue 23 Feb 2010 17:44:53 GMT Install Date: Wed 24 Feb 2010 11:20:27 GMT Build Host: hauseck Group : Productivity/Multimedia/Video/Editors and Convertors Source RPM: ffmpeg-0.5.21861svn-0.pm.1.4.src.rpm Size : 1053957 License: LGPL v2 or later and some code GPL v2 or later Signature : DSA/SHA1, Tue 23 Feb 2010 17:45:31 GMT, Key ID f899f20d9a795806 Packager : mantre(a)links2linux.de URL : http://ffmpeg.mplayerhq.hu Summary : Hyper fast MPEG1/MPEG4/H263/RV and AC3/MPEG audio encoder Description : ffmpeg is a hyper fast realtime audio/video encoder, a streaming server and a generic audio and video file converter.

I have the same version as you and when I try encoding using -ab 32, ffmpeg picks 128k as the bitrate. If add the k, I get the encoding using a 32k bitrate. > But anyway this does not explain why it worked for me and not for > Peter. In another response Peter shows the error and, from a quick Googling, it appears that the specific codec used is not yet supported by libavcodec, ffmpeg, or any other package that depends on libavcodec.
