Video Rotation only rotate resolution spec, not content

[fchristysen]

Hi, I'm currently trying to rotate GPUPlayerView using gpuPlayer.rotation = gpuPlayer.rotation - 90f
The view is rotated correctly, but the video content being played is not rotated correctly instead stretch based on new rotated resolution. How can I correctly rotate the content?

Some have suggested using app:surface_type="texture_view" for rotating exoplayer, but not sure how to do this with GpuPlayerView

Thanks!
