Camera2Base

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)

abstract class Camera2Base

Wrapper to stream with camera2 api and microphone. Support stream with SurfaceView, TextureView, OpenGlView(Custom SurfaceView that use OpenGl) and Context(background mode). All views use Surface to buffer encoding mode for H264. API requirements: API 21+. Created by pedro on 7/07/17.
