Just use it Here is the problem i have an IP camera that stream a h264 video using RTSP protocol, all i want to do is read this stream and pass it to Open CV to decode it, using If the h264 stream was a constant frame rate you might be able to push rtp data to ffmpeg with out the timings setting the inputs fps, but I dont know of any h264 rtp streams that work like that. Open-cv offers such functionality via the cv2. 264 streams. 264 video frame. Example: h26x-extractor file1. 264 data using FFmpeg and C++.
