hi !
My first post here ! I want show visualization like :
Menu Audio -> Visualization -> Oscilloscope, Spectre Analyzer...
i have found : --audio-visual <String>
but when i run vlc with :
vlc /path/to/my/music.ogg --audio-visual spectrum
OR
vlc /path/to/my/music.ogg --audio-visual scope
OR
vlc /path/to/my/music.ogg --audio-visual oscilloscope

I have no visualization. I can read this message :
main private error: o visualization module matched "spectrum"
main audio output error: cannot add user filter spectrum (skipped)
main private error: o visualization module matched "scope"
main audio output error: cannot add user filter scope (skipped)
...

Do you know how can I launch Visualization from command line
Thank you very much

It's a bit complicated. Most of the visualisations are part of the "visual" plugin. So you should use: vlc <input> --audio-visual visual --effect-list spectrum (or something like that)

that works verywell ! thank you very much
