Got a weird bug across multiple machines running 3.7.2. Content plays fine on first loop. When it loops the second time, the frame-rate drops to 12. Content is 30 minutes long. Before loop, frame-rate is at 24-40 (depending on machine). On loop, all machines drop to 12-14 FPS. Codec is HEVC.
After some testing, I've learned that the hang up is from an audio file I have running. It's a separate layer of 16x16 pixels, 2.5 hours long. If I turn that layer off, the frame rate goes up. But I need that audio running.
Next will try baking the audio into my 30 minute video loop and see what happens.
Will also try turning the opacity down on the audio layer and moving outside of the projector field.
Any other ideas / suggestions?
