I have an Oculus Rift S and when I play some 5K HEVC videos encoded the player always turn on the "DirectShow" feature and when i try to turn it off, it instantly turns on again.
The video seems to runs well on VLC and the Windows 10 player.
When I play the video with Directshow it's shuttering and when I look into the task manager my CPU is used at 100% while my GPU idle.
I tried installing the HEVC thing at 1$ on the Windows store, LAV Filter, Ffdshow without any changes.
