I'm having trouble with the current release of ffmpeg, it transcodes .mp3 to .wavs in a format that is unsupported by my client.



How can install this version?



ffmpeg version 0.7.3-4:0.7.3-0ubuntu0.11.10.1, Copyright (c) 2000-2011 the Libav developers
built on Jan 4 2012 16:08:51 with gcc 4.6.1


EDIT



The problem I am trying to resolve is transcoding an .mp3 to .wav. Our client has an identification service that determines a song from the .wav. When I pass the .wav that ffmpeg has generated



exec ("ffmpeg -ss $start -t $duration -i $shellArgSongPath -f wav -ar 44100 somefile.wav");


I receive an "Audio format not supported"



My guess is that the default codec used to transcode from .mp3 to .wav has changed. Would anyone happen to know what that was in the previous version?

This program is not developed anymore and is only provided for compatibility. Use avconv instead (see Changelog for the list of incompatible changes).

According to our commentstorm I'll assume that there is either a regression in libav or a bug in your application that is giving you the "Audio format not supported" message. You can try compiling ffmpeg (from the FFmpeg project, not libav). ffmpeg often works when avconv fails, in my experience. This will create a "local" build of ffmpeg, so it won't interfere with your ffmpeg/avconv from the repository:



sudo apt-get install build-essential yasm
cd
wget -O ffmpeg.tar.gz "http://git.videolan.org/?p=ffmpeg.git;a=snapshot;h=HEAD;sf=tgz"
tar xzvf ffmpeg.tar.gz
cd ffmpeg-HEAD-*
./configure
make


Now try ffmpeg. Note the ./ before ffmpeg, and this example assumes the input file is in your home directory. The output will be placed in your home directory:



cd ~/ffmpeg-HEAD-*
./ffmpeg -i ~/input.mp3 ~/output.wav


If this works you may consider actually replacing libav and installing ffmpeg: How To Compile FFmpeg and x264 on Ubuntu.
