kdenlive unable to export MP4 with error "Unsupported audio codec: libmp3lame"

2013-08-04

So after upgrading to 12.04 on Ubuntu from 10.04, I cannot export my videos from kdenlive with MPEG-4 option, with the error message "Unsupported audio codec: libmp3lame"

After installing the lame library with the command:

sudo apt-get install libmp3lame0 (the last letter is zero)

The issue is still there, so tried another way next

sudo apt-get install libavcodec-extra-53

Now it works!
