[Ffmpeg-user] MPEG layer 1 encoding?

[Kevin Weiner]

Is it possible to specify mpeg layer 1 audio encoding from the ffmpeg
command line? I couldn't find anything obvious. Thanks.

No. What do you need layer 1 for anyway? Nobody uses that.

Mpeg1 Layer 2 = mp2
Mpeg1 Layer 3 = mp3

=>
-f mp3
or
-f mp2

The OP requested 'mpeg layer 1 audio encoding' so if that is needed in a
muxed file, shouldnt it be '-acodec mp2' (or 3) ?

That would give layer 2 (or 3), whereas the OP asked for layer 1. FFmpeg
can't encode MPEG audio layer 1 (or 3 for that matter), only decode. IIRC
mjpegtools has a layer 1 encoder.
