Best video settings for streaming media on Gear VR?

Hi everyone,

currently I am trying to stream a video as a texture via the media framework.
I have looked everywhere to find the best settings to render out the video.
As far as I got was the H264 codec and a mp4 container, but what’s about the Bit rates, resolution etc?

The only hint I got was by downloading the example video from epic and check out their settings.
This has the following settings : resolution 640x360, 30fps, a total filesize of 16,86 MB, a datarate of 360,42kBit/s and a AAC stereo 44.100kHz.

Are those the best settings to have?

Hope you can help
