@learnermaxRL You need to use some kind of RTSP client for this. The potocol described in RFC2326 and its generic impl is hard. Also RTSP negotiation requeres a lot of overhead data processing, so it suits only for continuos video & audio recieving because of big "click-to-live" delay (for negotiation processes)

The best way is to use ready-for-use RTSP lib. Also can be useful for some tasks cli-based video players like ffplay, vlc or others. Anyway, you could implement you own version of simple (TCP-only or UDP-only) client using Twisted framework.

But if you need to recieve only one video frame, i recommend to use JPEG snapshot feautures (Hikvision ISAPI provides this feauture)
