I've updated the patch to make things build, but it does not work for me. I am
getting these elements:

libvisual-gl:  libvisual_gl_projectM: libvisual projectM
libvisual-gl:  libvisual_gl_nastyfft: Libvisual NastyFFT plugin
libvisual-gl:  libvisual_gl_madspin: libvisual madspin port
libvisual-gl:  libvisual_gl_lv_gltest: libvisual GL analyser
libvisual-gl:  libvisual_gl_lv_flower: libvisual Pseudotoad flower, yello


But none of them work for me:

gst-launch filesrc location=$HOME/Music/1.mp3 ! decodebin2 ! tee name=t ! queue
! audioconvert ! libvisual_gl_madspin ! glimagesink t. ! queue ! pulsesink

=> just a white window

gst-launch filesrc location=$HOME/Music/1.mp3 ! decodebin2 ! tee name=t ! queue
! audioconvert ! libvisual_gl_madspin ! gldownload ! xvimagesink t. ! queue !
pulsesink

=> just a black window

When taking a peek into the debug log, it looks like it is doing some work
though:
