using ffmpeg to convert from flv to mp3 gives the following result
] ffmpeg-0.6.1 >> ffmpeg -i name.flv name.mp3 FFmpeg version 0.6.1, Copyright (c) 2000-2010 the FFmpeg developers built on Feb 14 2011 12:33:38 with gcc 4.1.2 20080704 (Red Hat 4.1.2-48) configuration: libavutil 50.15. 1 / 50.15. 1 libavcodec 52.72. 2 / 52.72. 2 libavformat 52.64. 2 / 52.64. 2 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0.11. 0 / 0.11. 0 [flv @ 0x10869420]Could not find codec parameters (Video: 0x0000) [flv @ 0x10869420]Estimating duration from bitrate, this may be inaccurate Input #0, flv, from 'name.flv': Metadata: audiocodecid : 5 duration : 10 videocodecid : -1 canSeekToEnd : true Duration: 00:00:10.17, start: 0.000000, bitrate: N/A Stream #0.0: Video: 0x0000, 1k tbr, 1k tbn, 1k tbc Stream #0.1: Audio: nellymoser, 8000 Hz, mono, s16 Output #0, mp3, to 'name.mp3': Stream #0.0: Audio: 0x0000, 8000 Hz, mono, s16, 64 kb/s Stream mapping: Stream #0.1 -> #0.0 Encoder (codec id 86017) not found for output stream #0.0
you can see in last line it says codec id 86017 not found.
when i run following command:
ffmpeg -formats > ffmpeg-format.txt
mp3 is listed in available formats as
DE mp3 MPEG audio layer 3
.What can be the error.is it that mp3 codec is not properly installed?Help will be appreciated
It looks like your FFMPEG wasn’t compiled with libmp3lame. See this post:

If you can’t compile it on your own you’ll have to search for a binary that does support it.
