I have problem with playing HEVC encoded videos in DeoVR on Windows 10 on laptop with RTX2060. I installed the HEVC Extension from Device Manufacturer, but it didn't help. DeoVR runs over DirectShow and I cannot turn DirectShow off. I want to play 8K HEVC video, it runs without any problem on different laptop also with RTX2060 with DirectShow disabled. Now it does not play, only shows black screen behind the player GUI. I tried installing LAV filters and it played the video, but it was really laggy and not usable. Windows Video plays the video correctly. How can I fix this?
