--- Comment #25 from Pauli <suok...@gmail.com> 2010-02-27 06:39:33 --- I vote for NOTOURBUG too. Maybe ddx could be a bit better optimized for XGetSubImage that flash is using but in end we can't get it perform well enough anyway without modifying the blob. So what exactly is happening to slow down here: -Flash is playing the video to vram. -Flash calls XGetSubImage multiple times per frame to read back the whole video. -XGetSubImage tries to copy data from VRAM to system memory but there seems to be huge latency for CPU to read the data that was just written by GPU.
