HEVC Main 10 video playback is heavily stuttering
I don't think it's HEVC, I think it is PlayReady DRM. Both Netflix and HBO Max use PlayReady DRM, and Widevine DRM when PlayReady isn't available.
For me, this issue has been happening since the first release of the Nvidia 30 series drivers. Now it only happens for the first ten seconds with each Mouse hover preview on Netflix and some HBO Max content. At the time of my Video, HBO Max didn't use HEVC. Anyway, it only lasts about 10 seconds on both Netflix and HBO Max. And yes, this only seems to happen with 4K displays. It affects each version of HDCP differently. My older 4K monitor had HDCP 2.0 and my new monitor has HDCP 2.2.

Note: HBO Max kept Jittering for 10 seconds with HEVC uninstalled. I had to disable PlayReady DRM for the jitters to go away. For netflix, it only happens with 4k and ATMOS content (Excluding most Anime). BTW, disabling Playready (or uninstalling HEVC) is not an option because doing so will not allow the viewing of any Netflix 4K/ATOMOS content.
jesseinsf well, it definitely is HEVC because the same video works fine on LG TV browser and VLC player on the computer. It starts to jitter, stutter (whatever you call it) when I try to play it into edge browser.
It did fine a few months ago with the same videos.
p.s. I don't have Nvidia, just nice old Intel 630...
No issues whatsoever here with 1080p HEVC Main10 (x265, bframes=12), or a 2160p HDR HEVC Main10 file in Movies & TV.
The same 1080p file is a weird stuttery mess if I remux it to MP4 and drag and drop it on Edge Dev.
HEVC Extensions from Device Manufacturer 1.0.41023.0 with an AMD GPU on 21H1.- Well, I never wrote that I have encountered HEVC decoding issues with anything else than Edge (the internet browser). I use Netflix and VLC player with no problems.
Very frustrating issue. It appeared a year ago and never been fixed.
