Video not displaying on Android 16 - SELinux blocks dmabuf access for decoder-texture

[mikaelwills]

Video encoding/decoding works at the WebRTC level (EglRenderer receives and renders frames), but the
decoded frames don't reach the Flutter texture.

SELinux repeatedly denies dmabuf access for the decoder-texture thread:

decoder-texture: avc: denied { getattr } for name="/" dev="dmabuf"
scontext=u:r:untrusted_app:s0 tcontext=u:object_r:unlabeled:s0
tclass=filesystem permissive=0

Device: Pixel 6, Android 16 Developer Preview (API 36)
Works on: iOS, likely earlier Android versions

It definitely works on Pixel 6a, Android 16.
Can you share some logs?
