opengl on top of video
Locked
 
|
Hello,
I have a python-gstreamer app that shows video. It uses xvimagesink and links it to a gtk.DrawingArea. This works great. Now I want to overlay some graphics, dynamically generated from real time data. Opengl seems like a good choice to render the graphics. But I have no clue how to combine the video and graphics. I don't think they are made to work with each other.

I'm working on the same issue right now.. no solution as of yet. I'm looking at GtkEventBox and the following example. http://library.gnome.org/devel/gdk/2.22/gdk-Windows.html#composited-window-example However nothing is working yet... Let me know if you find a solution ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

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.
