H.264 Video is unstable on Quest 3 (black screen/freezing) - No issue on Quest 2

Hello! Our team has been developing a 360 video-based app for Quest (using Unity game engine). After getting Quest 3 headsets, we've discovered evidence that video playback is unstable on the Quest 3, when we had no issues on the Quest 2 with the same APK build.

Specifically, the H.264 codec is not stable on the Quest 3 and we are having issues with the video either turning black when paused (via AVPro Exoplayer Unity plugin), or not being able to resume playing after being paused (via the built-in Unity video player or Meta Quest TV app). The H.265 codec appears to work just fine, however we aren't always able to use this format and we want H.264 to work. The issues for H.264 are present both in our Unity app and also in the Meta Quest TV app, indicating this is a hardware/OS-level issue with the decoder for H.264 video only on Quest 3, and not on Quest 2. I have been able to prove this via Android Logcat error messages I have captured while playing video (see below).

Below are my observations when testing video playback on the Meta Quest TV app, Unity via AVPro, and Unity via the built-in Unity video player. The below is consistent when using either 8k (7680x3840) or 5.7k (5760x2880) 2D (equirectangular) 360 video at 29.97 fps. MetaStoreHelp or Ryanality could you please pass this important information along to the appropriate engineering teams?

*NOTE: I am unable to post the full information in this post because my post gets marked as spam if I do, presumably due to the long length of my post. As a workaround, I have posted the information over on the AVPro Github.
