Hi!


I have a two pc stream setup today. But i have a project coming up and i need to get a webcam feed from the other side of my house. Since i do not want to run a 10m+ usb cable, i where thinking of using this setup

Raspberry pi 3 connected on wifi. (its possible to ge cable. But if no need, then why)
logitech c920
The ndi plugin to send the video to my dedicated stream pc.

The question is will the pi have support and power to run obs.

Does the raspberry cpu (quad-core ARM Cortex A5) support ssse3 witch is the minimum for the ndi plugin to run.

Like the title says there will be not decoding on the raspberry its only going to send the cam feed with the ndi plugin over the local network.

Note, i have done a rtmp server setup before and did not like the output quality, might be to incompetents.

if you have any answer or other suggestions please let me know!

The raspberry pi lacks the hardware support for scene composition functions used by obs.

No SBC is able to run obs.
You're going to need to find another method to get the stream off of those boards. Running something pure NDI based may work.

You can get a very low latency stream with "mjpeg streamer" from the pi and play the stream with the media or vlc source. (Have done this multiple times)

You can use ffmpeg to get the (already encoded) stream from the webcam and send it to OBS via UDP for example. Then the raspberry does not need to reencode.

However I recommend cables instead of wifi

After a lot of tinkering and hassle i got a stable good local stream. that i can use in obs and onward.

A note first before i reveal. i bought a ip cam for 180 euro first. got home installed it got pissed. i had 7avg. fps at 720P for 180 FUXXXX euro's. went straight to the store and they give me an discount on the raspberry for my trouble.


So easy setup.

Hardware.
1. Raspberry pi 3b
2. logitech c920
3. old cpu fan
4.broken usb cable.

I hotglued the old cpu fan on the case and wired it with usb. Temps got from 75c to 45c
i plan to keep it going 24H so im better safe then sorry.

Software.
Tried raspian did not find my usb cam, ubuntu mate, not stable at the load req, and bad fps audio not synk.
Motion os had alot of trouble with audio.


So i went with
https://www.linux-projects.org/rpi-videoconference-demo-os/

I just flashed the sd card and started the pi and it where more or less good to go.

Then i started the stream in my browser and captured it in fullscreen in obs.


I have not been able to get the raw stream straight into obs (yet)


And with this system it is acually possible to use the pi as exampel, a file server in the same time as stream if one wanted to.

Hope it will help someone,
