exoplayer not handling video orientation from video metadata

[ryango]

MediaPlayer handles playing videos filmed in portrait mode without issue, playing them with the proper orientation. ExoPlayer with the provided MediaCodecVideoTrackRender does not. Wish I could set an orientation hint with the MediaMetadataRetriever. I guess I can create my own GLSurfaceView and adjust this onDraw, but this is certainly not ideal.

Using a TextureView would probably let you do this pretty easily.

I'm not sure if it can be done in MediaCodecVideoTrackRenderer, since I can't see any underlying support in the MediaCodec or Surface to do it. If you know of a way to add this, please let me know.

@ojw28 really good suggestion. Thanks. You're right that it would be hard to do that within the track renderer. I ended up wrapping the ExoPlayer functionality in a TextureView kinda like how VideoView wraps MediaPlayer functionality. I handle the transform there.
