Thanks, with the latest release I have compiled CinGG with Cuda without any problems. I've loaded a three-media project: 1- h264 .mp4 2- h264 .mp4 (made with the same smartphone within seconds of each other) 3- h264 .3gp (same codec as 1 and 2 but different container, I used another smartphone) 1 and 3 give error and are not displayed in timeline. 2 don't give mistake and is displayed normally. Strange, since it is exactly equal to 1. Error is: Failed to get HW surface format. Failed to get HW surface format. Failed to get HW surface format. Failed to get HW surface format.
