org.webrtc.VideoEncoderFallback

All Implemented Interfaces:

VideoEncoder

public class VideoEncoderFallback
extends WrappedNativeVideoEncoder

A combined video encoder that falls back on a secondary encoder if the primary encoder fails.

Method Details

createNativeVideoEncoder

public long createNativeVideoEncoder()

Description copied from interface: VideoEncoder

The encoder implementation backing this interface is either 1) a Java encoder (e.g., an Android platform encoder), or alternatively 2) a native encoder (e.g., a software encoder or a C++ encoder adapter). For case 1), createNativeVideoEncoder() should return zero. In this case, we expect the native library to call the encoder through JNI using the Java interface declared below. For case 2), createNativeVideoEncoder() should return a non-zero value. In this case, we expect the native library to treat the returned value as a raw pointer of type webrtc::VideoEncoder* (ownership is transferred to the caller). The native library should then directly call the webrtc::VideoEncoder interface without going through JNI. All calls to the Java interface methods declared below should thus throw an UnsupportedOperationException.
