Can't convert to OPUS [extension not recognised]

[YuriKharkov]

I can't convert my FLAC files to OPUS.
Error log:
[AVFormatContext @ 0000024ab7e22840] Unable to choose an output format for 'ffmpeg'; use a standard extension for the filename or specify the format manually.
[out#0 @ 0000024ab7e214c0] Error initializing the muxer for ffmpeg: Invalid argument

Encoding test failed. CHECK OUTPUT ABOVE

Hi, you don't have to add ffmpeg to parameters field, it is automaticallt included. Just include the encoding parameters.

Still not working, says "unable to choose output format

Do I have to install libopus separately?

You should not install anything else. I'm unable to reproduce the issue, I can convert to opus trouble free.
Have you tried creating an audio preset using the wizard?

i fixed the issue, it was an ffmpeg problem, had to install ffmpeg from software, rather than externally dowanloading it and adding it to system path.

I'm afraid application expects ffmpeg.exe in application path, nowhere else.
