Ooooh, that sounds like the uploads of the video frames are starving the main loop. What happens is the main loop processes stuff depending on their priority. If you always have a texture to upload and that' happen to be higher priority than clutter_threads_add_idle(), then the callbacks given to clutter_threads_add_idle() are never called. To verify the hypothesis, you can try playing with the priority property of the sink or use clutter_threads_add_idle_full() which takes a priority. That also means that the clutter thread is taking 100% of the CPU? -- Damien _______________________________________________ clutter-app-devel-list mailing list [email protected] http://lists.clutter-project.org/listinfo/clutter-app-devel-list
