Hello, I am trying to synchronise playback of four videos, and after start metro, they are gradually dissynchronizing. Codec is Photojpeg mov, playback is smooth. Metro is set to 25, but fps is aroun 40.

When I get time, each video delays 3 frames , then that before. I tryed to play four jpeg/png sequencies,

and they were accurately synchronised by counting, but fps was very slow, aroun 8 . Is there an option

how to achieve exact control of the same playback of all videos, or same framerate? Thanks.

Ok I understand that I wrote it in very general. This is what I did, I have used a counter to sync frame counting of videos. It work well, but please, I don't understand why the movies with longer duration (2 sec) slow down to 12 fps. When I use 1 sec long videos fps is close around 25, and by pulling down a ms in metro, I can speed up fps to whatever value. But not in 4 sec long videos. Is it depending on power of graphic card, or ram, or am I missing something? I think there is not so big difference between 1 sec and 2 sec long videos of same quality for processing. Thank you.

Please any suggestion why a can't play two HDTV 1080p videos in 25 fps longer then 1 second ? Or four videos 824 x 1080 dim. ? (pc specs. are i7 7700HQ, geforce GTX 1060, 16gb ram, win10) It must do that, please any link who solve that. Thank you very much.

set @output_texture 1 @cache_size 1 on all the videos.

set @output_texture 1 @cache_size 1 on all the videos.
adjust the cache_size to your needs.
make sure you are running in 64 bit.

Thank you Rob, it's working! Please one more think, don't you know, why the textures in

second output video are white? I didn't change anything, only what you wrote and they are lost.

First window is ok. Thanks a lot for help.

Once output_texture and cache_size enabled add @shared 1 and create one jit.world for each screen...

Hello,

Thanks Generalth, it was missing @shared and @shared_context.
