FFmpeg: ERROR Unknown encoder '2'

Disclaimer: Full commandline and console output missing.

[PROBLEM]

I tried to do something with FFmpeg and got the following error:

Unknown encoder '2'

In orange.

A newer FFmpeg version gave me a hint:

Multiple -c, -codec, -acodec, -vcodec, -scodec or -dcodec options specified for stream 0, only the last option '-c 2' will be used.

[SOLUTION]

I typed "-c 2" for 2 audio channels, but the correct way is:

Code: Select all

-ac 2
