IceCandidate是一个模板类，里面主要包含着会话描述协议。
public class IceCandidate {
public final String sdpMid;//描述协议的id
public final int sdpMLineIndex;//描述协议的行索引
public final String sdp;//会话描述协议
public IceCandidate(String sdpMid, int sdpMLineIndex, String sdp) {
this.sdpMid = sdpMid;
this.sdpMLineIndex = sdpMLineIndex;
this.sdp = sdp;
}
public String toString() {
return sdpMid + ":" + sdpMLineIndex + ":" + sdp;
}
}
SdpObserver是来回调sdp是否创建(offer,answer)成功，是否设置描述成功(local,remote）的一个接口。
/** Called on success of Create{Offer,Answer}(). */
public void onCreateSuccess(SessionDescription sdp);
/** Called on success of Set{Local,Remote}Description(). */
public void onSetSuccess();
/** Called on error of Create{Offer,Answer}(). */
public void onCreateFailure(String error);
/** Called on error of Set{Local,Remote}Description(). */
public void onSetFailure(String error);
CameraSession是用来回调相机信息的一个接口
public interface CreateSessionCallback {//创建相机描述的回调
void onDone(CameraSession session);//成功
void onFailure(String error);//不成功
}
public interface Events {
void onCameraOpening();//当相机打开
void onCameraError(CameraSession session, String error);//相机发生故障
void onCameraDisconnected(CameraSession session);//断开连接
void onCameraClosed(CameraSession session);//关闭
void onByteBufferFrameCaptured(
CameraSession session, byte[] data, int width, int height, int rotation, long timestamp);
void onTextureFrameCaptured(CameraSession session, int width, int height, int oesTextureId,
float[] transformMatrix, int rotation, long timestamp);
}
void stop();//回调到相机停止工作
