Seems like it does not find the encoder Nah but really, i think you didn't download properly ffmpeg

[18aKissD]

Yes you were right.

For everyone coming with the same issue, the fix is installing ffmpeg from source manually. This is needed because Ubuntu messed up ffmpeg with libraries that are outdated and won't install properly (just like mp3Lame package). So

• Uninstall ffmpeg with sudo apt remove ffmpeg then sudo apt autoremove to remove the libraries that were downloaded but is not needed now as you removed ffmpeg. • Install dependencies from here. • Always go with building and do not go with the apt installs, this is the most important part. !Read the site carefully because there are way so many codecs I don't know which ones do you want!.

There might be some installs that take some time but be patient please.

Hope this helps someone :)
