Detailed Description

Preview window control based on TextureView.

The difference between this preview window and NvsLiveWindow is that it is derived from TextureView instead of SurfaceView, and the PreviewView window is based on TextureView. It is smoother than SurfaceView when performing zoom and rotations. Warning: Individual phones may experience deadlock when drawing with TextureView, please refer to https://stackoverflow.com/questions/15771971/anr-textureview-on-galaxy-s2-gpu-driver-issue. and https://bugs.chromium.org/p/webrtc/issues/detail?id=5702 There is currently no effective solution, so we recommend users to use NvsLiveWindow based on SurfaceView, if users have to use NvsLiveWindowExt there will be a risk of encountering a deadlock problem!

Warning

In the NvsLiveWindowExt class, all public APIs are used in the UI thread! ! !
