I am using the ExoPlayer Library, which expects a Surface, however i couldn\'t find any Method, which retrieves the underlying Surface of the Textureview. Any Ideas?
First step is to get the SurfaceTexture from the TextureView using the getSurfaceTexture() member function.
SurfaceTexture surfaceTexture = textureView.getSurfaceTexture();
Then create the Surface object from the constructor Surface(SurfaceTexture surfaceTexture) that will accept the SurfaceTexture from your TextureView object.
Surface surface = new Surface(surfaceTexture);
For more information take a look at this issue report. It confirms that by constructing the Surface object in the manner I described it is possible to use the Surface from a TextureView with ExoPlayer.
