Hi, I just tried Clutter-0.2.1, and its performance is much better than the previous one. On my 5200fx, the video is now more fluid than what I had on my 7600gs+clutter-0.2.0.
There is one problem I seem to encounter, when playing back long video files in my application, my computer will start to swap after 30 minutes. I haven't tried yet to reproduce it with the video-player demo, but since I almost ripped it off to build mine... there aren't much differences. Have you experienced the same?
