Verint Nextiva

We have old analog camera's around the space that have been used in the past but are unconnected now. They do have power and they work!

Sk1llz has had a donation from Griffid with some old video encoders. One of them is a 8 channel Verint Nextiva S1708e

Peetz0r, participant at both spaces, re-donated the decoder and tried to make it work. Spoiler alert: it works!

Network config

The thing does not have a web interface. It does have telnet and it streams video over RTP.

DHCP is enabled right now, and it's IP is 10.42.43.92.

Video config

Telnet to the thing, and go (6) Advanced => (1) Video => (X) Input X => (1) Encoder 1 and make sure it looks like this:

Command: 

Change (11) Remote IP Address to your device (let's say, a laptop running linux) and (12) UDP port to anything.

The led for the chosen input should now be flashing quickly. Preferably green, because that means that the connected input works. But red is okay for testing your config.

Now move over to your linux machine. At first I tried vlc and I even fiddled around with SDP files. Then I stumbled upon https://wiki.london.hackspace.org.uk/view/Project:Verint which barely helped. The next day, I found this mailing list thread and especially this mail.

Then I created this command line:

gst-launch-0.10 -e -v udpsrc port=2543 ! application/x-rtp,media=video,payload=121,clock-rate=90000,encoding-name=MP4V-ES,profile-level-id=1 ! rtpmp4vdepay ! decodebin ! autovideosink

It works!!!
