[gst-devel] opengl on top of video

[Olivier Aubert]

Hello

Depending on the nature of your visualization, you may want to try the
rsvgoverlay element, which should be included in the latest
gst-plugins-bad pre-release. Insert the rsvgoverlay element in your
pipeline, and feed it SVG data (through a property or through a
data_sink pad) generated from your real-time data.
