Additional information

I have a media source with a quicktime video with alpha enabled. When i start the scene with this media source it first shows the last frame of the video and then starts playing the video from the first frame. I have tested it with exporting the video with the last frame fully transparent and this solves the issue but it makes it impossible to end the video on the last frame.

i have also tested it without using transparency (a h264 mp4 file) and it has the same problem

problem persists on older versions (have tested it al the way back to version 16)

I have also been testing with framerates and the problem was most persistent with lower framerates (around 25 fps) and less persistent with higher framerates (around 50 fps) but the problem never really disappeared. the source material for the test was 25 fps

i started a post on the forum:
https://obsproject.com/forum/threads/last-frame-of-media-source-flashes-before-starting-video-playback.121882/

somebody confirms that the problem is also on the linux versions

i have been using the windows version (32 and 64 bit versions)

this is the output of the log file:
