Question

I\'m trying to convert AMR audio files to MP3 using FFMPEG. I\'m running on Ubuntu 10.10 with VBox on Windows 7 host and i\'ve installed ffmpeg by running sudo apt-get

Answer 1

My command for Thunar custom actions:

ffmpeg -i *.amr -ar 12000 lastcall.mp3

Appearance condition *.amr and bellow: "image file"

Answer 2

Argh, those useless ubuntu questions regarding useless ubuntu packages.

Converting AMR to MP3 using FFMPEG

ffmpeg -i audio1.amr -ar 22050 audio1.mp3

This will convert audio1.amr file to audio1.mp3 having audio rate 22.05 Khz

Answer 3

I solved this by following the instructions here http://pasindudps.blogspot.com/2010/12/compiling-ffmpeg-in-ubuntu-1010.html after doing so I had no problem doing the audio conversion

EDIT: the link I posted is dead now, here's another one for Linux systems http://linuxers.org/tutorial/how-install-ffmpeg-linux and here's another for Mac OS X http://jungels.net/articles/ffmpeg-howto.html

UPDATED ANSWER:

Since I had to use this solution seems like the process has gotten much easier. On Mac OS you can simply use Homebrew:

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus --with-x265

Only Linux systems you can install from the repository:

sudo apt-get install ffmpeg

or

su -c 'yum install ffmpeg'

The FFMPEG website now has updated documentation and downloads for Windows, Mac or Linux as well; in case any further information is required.
