Nifi & rtsp or rtmp
Hello!
I am tasked to handle streaming video in rtmp or rtsp and have a quite short time to set it up. So I am wondering if Nifi is the best tool to use for this task.
I found this thread from 4 years ago: http://mail-archives.apache.org/mod_mbox/nifi-users/201709.mbox/%3C3A956343-EC9F-4AFA-975B-A9487BD04E79@acesinc.net%3E
and wonder if there are any development in that direction since then. I did not find anything more recent.
As far as I understand I can use ListenTCP and ListerUDP would be my best option in Nifi. Is this correct? Any guidelines how to set such flow up would be very appreciated. Would it be better/easier to use another tool?
Thanks & all the best
Valentina

Hi Jeremy!
Many thanks for your reply! Just forwarded your question to my colleague who is more knowledgeable about these requirements. Will get back to you as soon as I know more.
Thousands thanks again!
Valentina

Valentina,
I have something in an experimental state that could possibly be helpful to you. What I have is not a production solution but could be helpful for you if this is a one time thing or in a pinch. I do believe it could be made productionalized but it isn't something I plan to actively work on anymore so that would be up to you.
- If the plan is to capture and store raw video, what increment should those videos be stored in? Every 5 minutes makes a new file, 10, 3 hours, etc? As Joe mentioned this really matters for the NiFi framework portion of the answer. Understanding it isn't really as simple as a "copy" in this case.
- What is expected if a single frame is missed in the "increment" mentioned above. Understand RTSP is notorious for dropping frames so this case is highly likely.
- Does any video transcoding need to take place or simply capture and save in the same codec received over RTSP?
- What framerate is the producing RTSP stream generating? Would the capture need to be at the same or different rate as the source?
- Is the RTSP stream a solution that fully supports the entire RTSP protocol or something custom? Basically is it a product from a vendor or some custom application that might not utilize the entire RTSP protocol stack.
- Does the RTSP stream contain any DRM restrictions?
Thanks,
Jeremy Dyer

Can you describe what you want to be able to do with the streaming video?
Thanks

I was told that the videos should be stored and might be very large.
