how can we optimise performance?
I have 60 small quicktime movies running but the framerate is around 2 to 4 fps. Alltogether it adds up to 120MB. I have 1GB of ram. But I do not know if the quicktime object streams from disc.
The CPU load is still not very high. So where is the bottleneck?
i'm not a specialist but did you try to work on GPU with uyvy colors ?
maybe post your patch.
60 is a lot of movies.
without seeing the patch we can only guess.
make sure the movie resolution is only as big as necessary, make sure qt.movie dims are only as big as necessary, vade optimizations, etc. are you using opengl? who knows.
loadram might help. please remember the size of the qt file on disk is not the same thing as the size of the de-compressed file in memory. also jitter is limited in the amount of memory it has access to (2 gb maybe?).
I figured something. When I load all movies play and stop and play again without using start, I play only one picture of every movie and not the movie itself. In that case I have more than 30 pictures per second. That tells me that the problem is the streaming because when all movies are really playing I have only 4 pictures per second. Do you agree?
