--- Comment #17 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
Btw, if someone want to test, open an app with a fully back blackground. Using
any USB webcam, before the patch, if you block all lights the window is
slightly gray using the following pipeline, and is fully black with this patch:

  gst-lauch-1.0 v4l2src ! videoconvert ! ximagesink

Note that with glimagesink it makes no difference, as there is absolutly no
colorimetry support yet in libgstgl.
