Hi all, I did more experiment and found that the performance and memory consumption gets better if I downgrade to clutter-1.2 and clutter-gst-0.1. Also I ran valgrind against my player and there really isn't that huge amount of memory leakage reported by valgrind (actually there's only 1 definitely loss and many possibly loss in pango and other libraries), and from top's output the CPU usage had never gone more than 60% by my player. One more clue I found is that the performance went really really bad and memory consumption went crazy only when I render some actors with my video texture together, could there be something wrong to break the on-die memory controller of AMD Athlon X2 when clutter's constantly updating OpenGL texture while playing video?
Just in case the following are the output of my running test-yuv-upload with nothing but an white, empty window: test-yuv-upload.c: [caps] video/x-raw-yuv, format=(fourcc)I420, framerate=(fraction)30/1 ** (lt-test-yuv-upload:3856): CRITICAL **: Could not link elements Thanks for all your opinions again!!
