This is a good report. The whole video settings, the right-side menu during video playback with image controls (brightness, contrast, saturation, etc), video controls (zoom, pitch, yaw, etc) and others is missing.
The whole UI is definitely different to even Samsung GXR and other Android-derived systems, so it likely means the team is developing all the features from the scratch.
Any news on that when we could get these video controls to AVP?
Edit: It seems like "soon" based on information in another thread DariaDeoVR
