VRchat Video Playback PROBLEMS on AMD GPUs (22.11.2)

VRChat Version: 1275
Description of the bug:
the version of AVPro implemented in VRchat has a known issue that causes grief for users with AMD GPUs (including myself). Running the latest AMD drivers compatible with my GPU, version 22.11.2 which specifically has fixes for AVPro, I still have video playback issues in VRchat.
In specific, playing a video causes the video to stutter, or freeze and rewind momentarily. Sometimes, when multiple video playback instances are loaded within a single world, a full-blown Driver Timeout will occur, and the VRchat process will be ejected from rendering for the VRheadset.
Steps to reproduce (how did you encounter the bug?):
0) I've only experienced this with headsets from Meta/Oculus, but I haven't heard anyone mention that it's specific to those headsets.
1) Use an AMD RX-series GPU (RX Vega, RX 5xxx, RX 6xxx all confirmed by me). The RX 7xxx cards have some issues but have different driver releases and I cannot personally confirmed them.
2) install the latest AMD Catalyst drivers (22.11.2) compatible with your GPU.
3) log into VRchat.
4) Navigate to a world that has Video Playback
5) Play a video, really any video. A youtube video will do.
6) Watch how the video stutters, has loops of out-of-order frames, artifacts, or causes you to crash.
7) Check the Desktop to see if you've received a Driver Timeout (this occurs when the driver halts the process so that the driver doesn't crash the entire Kernel).
Any extra files? (output logs, screenshots):
Happy to provide, need to know what you'd like to see. This isn't a new issue.

Version 23.9.2 of the AMD drivers has resolved the stuttering for video players in VRChat.

NormWilson: Validating this on my 7900 XTX today.
EDIT: VALIDATED. The issue appears resolved at this time. Please use driver version 23.9.2 or newer.

Just to document, issue still persists with the latest AMD drivers for 6600XT (23.9.1 - 24.08.2023) with AVPro. Unity Player appears to work alright for me, however.

An alternative or temporary fix would be to fix the Brightness for 'Software/CPU' encoding. I think most here have looked that up to just to be greeted by a super dark video player where you can barely make stuff out

I see this is still tracked, 7900xtx here with AMD Adrenaline drivers 23.7.2 released 7/25/2023with occasional stuttering on videos but it will cause a driver time out as described by Kaishi. I am still on Windows 10.

Issue still present on AMD driver 23.7.2.
Vincil
Adrenalin Edition 23.7.1 which has a fix for vr performance and which has zero vr related known issues still this has this issue.

Is this issue specific to Windows 11 or is Windows 10 affected too? Recently updated someone from Windows 10 + Radeon 5700 XT + driver >22.5.1 (where they had no issues) to Windows 11 + Radeon 6750 XT, and now they're having the issue.

Update on the video stuttering issue with AMD GPUs and video players in worlds like LSMedia. The stuttering does not happen if you use VRchat on Steam in desktop mode. The stuttering seems to only happen when you are using Steam VR.

Still an issue on driver 23.4.3

Update on the video stuttering issue with AMD GPUs and video players in worlds like LSMedia. The stuttering does not happen if you use the Oculus version of VRchat. When I say Oculus version I mean the version of VRchat you can find in the Windows Oculus store that you can install on your Windows PC. The stuttering only happens if you are using Steam and the Steam install of VRchat. So it looks like the issue is actually a Steam issue with VRchat and AMD GPUs.
