opengl plugin

Hi, I’m using the opengl plugin to upload video to a texture but I’m having problems rendering it from my application’s main thread. I have an existing opengl application to which I want to add a video to texture a 3d elements but the plugin seems to render to its own context in its own thread. I want to be able to render the texture from my own main thread. How would I go about doing that with this plugin, is it possible? I tried playing with the callbacks in the glimagesink element but since the callbacks are called from a gstreamer thread, I cannot use the texture in my thread’s context.

Thanks

Denis

Re: opengl plugin

Hi,

This is possible. (you will need the head of git/gst-gl)
You have to share the contexts together.

Take a look at the 3 examples:

gst-plugins-gl/tests/examples/qt/qglwtextureshare/
gst-plugins-gl/tests/examples/clutter/cluttershare.c
gst-plugins-gl/tests/examples/sdlshare.c

Re: opengl plugin

Hello,
Have you got advices on how to improve the frame rate, though ?
(see my recent post "v4l2src & glupload at only 12 FPS?")
