JAVACV the rtsp of the Hai Kang webcam to the rtmp stream

Objective:

Using the javacv1.2 version, refer to the code on the Internet, encountered a number of very serious problems, the last one to eliminate the solution. The main issues to be addressed are:

Problem one, ffmpeg default is the way to use UDP, often the problem of packet loss, you need to change the UDP to TCP can be resolved, the following is the content of the error:

Input #0, RTSP, from ' RTSP://ADMIN:123123@192.168.1.64:554/STREAMING/CHANNELS/1 ': Metadata:title:Media Presentation duration:n/a, start:0.040000, bitrate:n/a Stream #0:0: video:h264 (Main), yuvj420p (PC, bt709), 2560 x1440, FPS, TBR, 90k TBN [Swscaler @ 000000001be02720] deprecated pixel format used, make sure you did set range Cor rectly [rtsp @ 0000000000F8C9A0] Max Delay reached.

Problem two, after TCP has not been set to switch, but has been around 50 frames can not get the frame, the return is always null, the problem is caused by the size of my Hai Kang camera is too big reason. Concrete has not yet been studied, but to solve the problem. But backstage still reported countless mistakes, do not understand what is caused. But the function is ready to use. The content of the error:

[Swscaler @ 000000001be02720] deprecated pixel format used, make sure you did set range correctly

Okay, go straight to the code. Help people please point a praise, study for a few days is not easy ah.

		} Recorder.record (frame);
		} grabber.stop ();
		Grabber.release ();

	Recorder.release ();
 }
}

To add a very serious problem is

Frame frame = grabber.grabimage ();

The memory problem. The frame's memory has not been released, and eventually the memory crash caused the application to die.

The Javacpp.jar version needs to be more than 1.3.1. I have used 1.3.3 test. The problem has been solved.
