cannot convert to mp3 by ffmpeg

[rahilm]

i cannot convert to mp3 using ffmpeg. when i do:

ffmpeg -i input.flac -acodec mp3 output.mp3

i get:

Unknown encoder 'mp3'

at the end the media info.

what codecs should i install? basically, this is linux mint so i guess everything should have been installed by default...

Hi!
You do not have to specify -acodec mp3, ffmpeg uses the output filename to choose the appropropriate codec.

I did:

ffmpeg -i loop.flac loop.mp3

i get this output:

ffmpeg -i loop.flac loop.mp3

Does activating the Medibuntu repository and dist-upgrade does any help?

[rahilm]

I already have medibuntu enabled..

Hi rahilm,

Some encoders are disabled in Ubuntu because of licensing issues. To enable mp3 encoding, and a few others, have a look at this page:

HOWTO: Easily enable MP3, MPEG4, AAC, and other restricted encoding in FFmpeg
http://ubuntuforums.org/showthread.php?t=1117283

After you have followed the steps recommended by this guide you may find that if you are using Karmic Koala and you wish to specify the mp3 encoder, and possibly add a few options, you will need to use -acodec libmp3lame, rather than -acodec mp3, followed by the options of your choice...

All the best,

Andrew

On Mint mp3 should be supported out of the box I believe. But as andrew pointed out, try 'libmp3lame' as the codec, as this is the correct name in the new ffmpeg syntax. To see which codecs are supported in your version of ffmpeg type:

ffmpeg -codecs

Good luck

ffmpeg: missing argument for option '-codecs'

FFmpeg option names change once in a while. FFmpeg from the Ubuntu repository lists available codecs with ffmpeg -formats.

I am trying to find if i am missing any dependencies..
