Camera1Base

abstract class Camera1Base

Wrapper to stream with camera1 api and microphone. Support stream with SurfaceView, TextureView and OpenGlView(Custom SurfaceView that use OpenGl). SurfaceView and TextureView use buffer to buffer encoding mode for H264 and OpenGlView use Surface to buffer mode(This mode is generally better because skip buffer processing). API requirements: SurfaceView and TextureView mode: API 16+. OpenGlView: API 18+. Created by pedro on 7/07/17.
