Convert FLV audio to MP3 in Linux

This is a variant on the instructions found at

Specifically, the ffmpeg I have installed on my version of Ubuntu does not support MP3 output, so I had to go through an intermediate WAV step. Of course, ffmpeg doesn't have an output keyword for wav, you have to define exactly what sort of wav file you want (in this case a PCM-encoded, signed, 16-bit, little-endian wav).


sudo apt-get install ffmpeg lame id3ed


ffmpeg -title 'My File' -i myfile.flv -acodec pcm_s16le -ac 2 -ab 128 -vn -y myfile.wav

Then, it's as simple as using lame to encode the wav as an MP3:

lame --preset cd myfile.wav myfile.mp3

Finally, set the ID3 tags:

id3ed myfile.mp3
