HEVC video decoding broken with B-frames
When Edge Chromium playing HEVC video, sometimes video will be similar to stuttering but audio is normal. To find out the cause of the problem, I test to playback many HEVC video, include videos ...
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.

jesseinsfThis problem happened when I played the local HEVC codec mp4 video, I don’t think it is related to PlayReady DRM
- 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.- I tried to install the HEVC extension before July 2020, and there is no such problem on version 21821 and 31823.
In the November release of version 33424 has been recently updated to version 41483 has shown a decoding problem.
