Thanks again @wolfman I just installed that but still nothing. I get ogg,mp3,flac,wav and opus but no aac (mp4). In the about section it say’s it is soundconverter 2.9.0-beta 1 not sure if this is the problem? I’m sure this is the one I was running with the aac (mp4) option.
I installed clementine and tried to encode something (it gives me the aac(mp4) option) and it fails and says " Could not create the GStreamer element “ffmux_mp4” - make sure you have all the required GStreamer plugins installed"
“Couldn’t find a muxer for audio/mp4, check you have the correct GStreamer plugins installed”
That states it’s included in the codecs package? and the soundconverter install.
