使用C ++从MJPEG流捕获视频

Question

I would like to capture a MJPEG stream using C++. Which options do I have? I have tried OpenCV with FFMPEG support but icvCreateFileCapture_FFMPEG_p is always returning null (after a few seconds of timeout). May I program a HTTP client by myself?

Regards,

M-JPEG is easy to capture. You send one HTTP request to the server and read back infinite response in multipart/x-mixed-replace format (Content-Type). Then you split it into frames, which are self-contained JPEG files... Subheaders might or moight not contain additional information such as timestamps.
