markdown 命令使用ffmpeg查找和转换

# Command find and convert using ffmpeg

I would like to combine the two following commands to find mp4 files and convert them to mp3 and save them with same name. The two command line:

`
find ./ -name '*.mp4'
ffmpeg -i video.mp4 -vn -acodec libmp3lame -ac 2 -ab 160k -ar 48000 audio.mp3
`

## With find's -exec functionality:

`
find ./ -name '*.mp4' -exec bash -c 'ffmpeg -i $0 -vn -acodec libmp3lame -ac 2 \
-ab 160k -ar 48000 ${0/mp4/mp3}' {} \;
`

## This should make xyz.mp4 to xyz.mp3.

Thanks, how I can delete the mp4 ? – molwiko Dec 10 '13 at 14:27

`
find ./ -name '*.mp4' -exec rm -f {} \;
`

 but check first if everything worked before deleting something. – chaos Dec 10 '13 at 14:32
