How to capture h264 video continuously using v4l2 API using c++?

Asked 2018-Mar-16 at 14:48

Below modified code, (original code saves a frame into the image), captures a frame and saves into a disk in a mp4 file. I am trying to change the code to capture the h264 video frames from web cam(Logitech c920). The web cam supports the h264 video streaming.

How do I modify code to capture and store streaming video in real-time until user exits from the program?

This looks like very complex to write the low level code to capture the webcam. But we can use the OpenCV which is more robust and does the same thing as what the question is asking. If you don't use opencv webcam feature, then you take a look at how OpenCV video capture is implemented.
