Stream to LAN Network reliably

[MultiDJRoni]

Hi

 

For our Company i am looking for a solution to locally stream a Desktop Window to three (and potentially more) TVs throught the Local Network. 

 

Since about two weeks we have settled on the Solution "LiveLAN" through "vMix" and have it running since then. 

 

However, even tho everything is connected via LAN, about every 30h the Stream fails and buffers indefinetely, until we reload the Page on the TVs. 

It does not seem that the stream itself is the Fault here, since the TVs fail at separate Times throughout the day. 

 

After a lot of googling i have not been able to find a similar solution to what i want to accomplish. 

 

Here is what we are looking for: 

 

Stream a Desktop to multiple Clients via LAN

The TV uses a Raspberry Pi 4 to receive and display the stream, currently with Chromium Kiosk Mode

The Delay can be about 1minute, so it does not need to be ultra-low-latency or anything

It needs to run reliably 24/7, without any manual maintenance needed

 

 

Thank you for your inputs!

cheap and dirty solution: have a script that resets the display devices every day.

Classic XY problem. You forgot to mention why you even want to stream a desktop PC to three TVs in the first place. Elaborate on that and someone might be able to give you a solution that doesn't congest your network with a constant video stream.

We have a logistics system running, and that shows certain Datapoints (like X spaces are free in X area) as Text that are relevant to see throughout the Building. Things like how many empty spaces are in a certain part of the warehouse. 

 

For this it would be an option to have a full on PC running the Logistics Software at every TV throughout the Building, but with that the costs go through the roof since a PC is much more expensive than a Raspberry Pi and also the licence for the Software are very expensive per User. 

 

BTW, the XY Problem is an interesting read, thanks! I hope this helps.

Yeah that would be the kind of solution i would implement haha, but the problem is that it can happen mid-day, sometimes after a few hours and sometimes after about 30h. So it would be possible that the script refreshes and 30min later the stream freezes again.

Couldn’t you basically have a dashboard through powerbi and display that on the screens? 
 

Alternatively if there was an extra pc you could have it refresh every x minutes and send a new screenshot to display on screen.

Have you tested other software?

Why are you using vMix?

Unachievable. Sort of.

Do you know VNC?

Unfortunately, the program that i want to stream from does not support PowerBi Exports/Dashboards

What kind of setup do you have in mind for the additional PC and Screenshot-display?

Well, vMix looked like the perfect solution to my Problem which is why we are currently using that. 

Another option we are going to try will be ScreenTask: https://github.com/EslaMx7/ScreenTask

I kinda know VNC, only used it once thus far. From what i know the raspberry would need a VNC viewer to view the desktop right? 

[mMontana]

Indeed. And a cronjob should check every time for VNC client to work... then launch it again if don't.
It's a LOT jankier, but involve a bazillion less bandwith.

On Windows I usually use UltraVNC "flavour", with the included hook driver for lower CPU usage and increased response time.

Thanks for all your Inputs. 

 

As an Update to this thread, we have "ScreenTask" running since over a Week now with no issues so far. So it seems we were able to find a Solution that works for us.
