I know that this solution probably works only for me, but damm it I spent quite a long time to find it. And this solution is actually not as simple as you thought.
First if you only have HEVC codec not LAV, it won't work because most 8bit videos will play poorly.
Second if you have LAV Decoder and set the hardware acceleration, it still won't work because 10bit files get really low frame rate. Even after you install HEVC, the same issue remains.
Third if you only switching the "direct show" on and off, it won't fix the problem either. The 8bit videos will give you trouble if you switch it off. So you will not think about turning it off.
So I disagree with you saying we had tried these things already. No, no , this is a fix that's very hard to find. Man o' Man. Thank God now I don't have to re-encode all those 10bit videos !
My gig always shows DeoVR running at 90fps. It's the video decoding that gave me the trouble. It doesn't matter if DeoVR runs at 1000 fps, if the video can only shows 20 frames/second, what good is the VR frame rate?
I like the 8.xx, that's the one hooked me up with DeoVR. but I don't want to stick to that version forever. I prefer using new version for their new improvement. Right now the video playback is no longer a problem. I can really enjoy using the new ones !
