Hi!
Thanks for the update. As explained, the plugin is not involved in the image decoding. It simply takes the content of the Media Texture “as-is” (filled by the UE4 Media Player), and projects it into the panoramic sphere with the same code used also for the still images.
The first thing I can think of, is to double check that you’re using the same general settings, in particular for the Media Texture size and its filtering options.
What system are you using to manage the user navigation? If you’re using the Lookup Texture method, ensure you’re using a low-resolution texture. Big textures are not necessary and on mobile platforms they can be expensive to use.
Could you provide a video recording of both the apps running inside the Oculus Quest 2? Here and here you can find instructions on how to record videos on Quest. Maybe we could notice something from the videos. Please send the link to download the files at support@unamedia.com . Thanks.
