ges and wavescope

[Thibault Saunier]

Hello,

I guess that what you want is to visualize the different audio clips as one
and for that you do not really want an effect but set your audiosink
appropriately. Something like that should work just fine:

    ges-launch-1.0 +clip Some.mp3 --audiosink="tee name=t ! queue !
wavescope ! videoconvert ! autovideosink t. ! queue ! autoaudiosink"
--track-types audio

BR,

Thibault Saunier
