gst123 as my regular audio and video player. I'm now using a
Saffire 6 USB interface, which works out of the box using
jack so I select
jack as audio-output device with the
-a option like this:
gst123 -a jack Music/audio-file.mp3
this is working fine.
But if I try to play a video file in
gst123 --fullscreen --audio-output jack Music/music-video.mkv
I get the following error:
Error: Failed to create Opus decoder => file cannot be played and will be removed from playlist
this is no problem when just running
gst123 selecting the system-default
pulseaudio output by not specifying any output device.
