I am able to convert it to wav
using:
ffmpeg -i audio.3pg audio.wav
but I need the command to convert it to ulaw
.
Anyone?
The simplest example is:
$ ffmpeg -i input -codec:a pcm_mulaw output.wav
Refer to ffmpeg -encoders
to see a list of available encoders.
[NULL @ 0250ef00] Unable to find a suitable output format for 'output.ulaw' output.ulaw: Invalid argument
.wav
as an extension, ffmpeg automatically guesses that you want a WAV container wrapping your PCM audio. If you do not want that, and instead need raw audio data in a .ulaw
file, you need to use -f mulaw
to force ffmpeg to use the PCM mu-law output format.
