JavaCV read flow settings Timeout

JavaCV class may be connected in the live stream FrameGrabber address decoding, Frame acquires frame information, commonly used as follows

FrameGrabber grabber = new FrameGrabber("rtsp:/192.168.0.0");

grabber.start();

while(true) { 

　　Frame frame = grabber.grabImage(); 

　　// ... 

}

In fact the internal call is ffmpeg's avformat_open_input () method to resolve network flow, and ffmpeg's avformat_open_input () is blocked by default.

When parsing errors encountered network flow, it causes the function does not return for a long time. For this purpose the set parameters -stimeout ffmpeg, pay attention to the unit is us -stimeout microseconds (1 second = 1 * 1000 * 1000 microseconds).

Usage (set before parsing the url):

1.javaCV

FrameGrabber grabber = new FrameGrabber("rtsp:/192.168.0.0");

// Increase the timeout parameter
grabber.setOption("stimoout", "5*1000*1000");

grabber.start;
while(true) {
    Frame frame = grabber.grabImage();
    // ...
}

　　

2.ffmpeg command line

ffmpeg -stimeout 5000000  -i rtsp://admin:[email protected]:554/h264...........
