unable to find a suitable output format for 'ffmpeg'

Question

I am using ffmpeg library for android.

I am passing one ffmpeg command for convert video format from .mp4 to .avi

<         


        

Answer 1

Same error may suggest ffmpeg simply needs to be told what format to output with the -f flag, because it failed to deduce it from the output file extension.

ffmpeg -i audio.xxx -f flac audio.flac
