I've experimented it with TextureView a bit a few months ago, you can
find my patches here:
https://github.com/flx42/vlc/tree/android-post-release
https://github.com/flx42/vlc-android/tree/android-post-release
It hasn't been rebased since and it's probably unstable. The goal was
to have a clean way to reorient the video.

There are also two problems with this approach:
- TextureView usually takes more memory and can be slower. I noticed a
5-15% increase in power consumption with a TextureView. This is really
a showstopper.
- Only SurfaceView can display DRM content. OK, we do not support it
yet but we might want in the future.

On IRC I discussed with someone named "Luca" (can't remember his exact
nick, luc4 maybe?) and he did something similar, he showed me a video
where he was able to get nice distortions during playback. Maybe if
you can find him he can help you :)
