ffmpeg mp3 conversion failed [closed]

Question

using ffmpeg to convert from flv to mp3 gives the following result

] ffmpeg-0.6.1 >> ffmpeg -i name.flv name.mp3
FFmpeg version 0.6.1, Copyright (c) 2000-2010 the FFmpeg developers

Stream mapping:
Stream #0.1 -> #0.0
Encoder (codec id 86017) not found for output stream #0.0

you can see in last line it says codec id 86017 not found. when i run following command:

ffmpeg -formats > ffmpeg-format.txt

mp3 is listed in available formats as
DE mp3 MPEG audio layer 3
.What can be the error.is it that mp3 codec is not properly installed?Help will be appreciated

Answer 1

It looks like your FFMPEG wasn't compiled with libmp3lame. See this post:

https://superuser.com/questions/196857/how-to-install-libmp3lame-for-ffmpeg

If you can't compile it on your own you'll have to search for a binary that does support it.

Try this, it worked for me.

sudo apt-get install ffmpeg libavcodec-extra-52

thanks to ffmpeg: convert audio-only flv to swf

Great solution, had to change package to sudo apt-get install libavcodec-extra-53 on Ubuntu 11.10 – Attrahent

I tried libavcodec-extra-52 on Ubuntu 11.04 but it says "Package 'libavcodec-extra-52' has no installation candidate" – Speedball

@Speedball see above. helped for 12.10 as well – Felipafelipe

1) For the latest Ubuntu, this is libavcodec-extra-53 2) This command may tell about a lot of conflicts and suggest awkward "solutions" involving uninstalling glibc. To overcome this, first run "sudo aptitude remove ffmpeg" and then reinstall it with "sudo aptitude install ffmpeg libavcodec-extra-53" – Kirwin

Answer 3

For ubuntu 11.10:

sudo apt-get install ffmpeg libavcodec-extra-53

For ubuntu 11.04, 10.10, 10.04:

sudo apt-get install ffmpeg libavcodec-extra-52

Resolution

I tried libavcodec-extra-52 on Ubuntu 11.04 but it says "Package 'libavcodec-extra-52' has no installation candidate" – Speedball

12.04 is the same as for 11.10 – Intrigante

sudo apt-get install ffmpeg libavcodec-extra-* worked on 12.10 – Meras
