# glvideomixer

Composites a number of streams into a single output scene using OpenGL in a similar fashion to compositor and videomixer. See the compositor plugin for documentation about the GstGLVideoMixerPad properties.

## Examples

     gst-launch-1.0  glvideomixer name=m ! glimagesink \
         videotestsrc ! video/x-raw, format=YUY2 ! glupload ! glcolorconvert ! m. \
         videotestsrc pattern=12 ! video/x-raw, format=I420, framerate=5/1, width=100, height=200 ! queue ! \
         glupload ! glcolorconvert ! m. \
         videotestsrc ! glupload ! gleffects effect=2 ! queue ! m.  \
         videotestsrc ! glupload ! glfiltercube ! queue ! m. \
         videotestsrc ! glupload ! gleffects effect=6 ! queue ! m.
