Just a note I have installed,
sudo apt-get install libmp3lame0
sudo apt-get install libavcodec-extra-52
sudo apt-get install libavcodec-extra-53
sudo apt-get install ubuntu-restricted-extras
I also installed libmp3lame-dev through Ubuntu Sofware Center
I also ran the INSTALL instructions after I did all these installation
calls.
avconv -codecs shows this:
D.A.L. mp3 MP3 (MPEG audio layer 3) (decoders: mp3
mp3float )
and so I tried:
avconv -i iTunes_test1_AAC-LC_v4_Stereo_VBR_128kbps_44100Hz.m4a -ar 22050
-ab 40000 -ac 2 -acodec mp3 22050.mp3
avconv -i iTunes_test1_AAC-LC_v4_Stereo_VBR_128kbps_44100Hz.m4a -ar 22050
-ab 40000 -ac 2 -acodec mp3float 22050.mp3
The same errors.
avconv -i iTunes_test1_AAC-LC_v4_Stereo_VBR_128kbps_44100Hz.m4a -ar 22050
-ab 40000 -ac 2 -acodec libmp3lame 22050.mp3
