IPTS Monitor OBS and freestreamcoder

Post by G1BVI » Sat Oct 15, 2022 6:02 pm

Hi All
Still trying to make this work!
My aim is to run a video on my HP i7 laptop running OBS.
I set this all up with callsign etc..
I run freestreamcorder v 2.28 and get the green light.
The IPTV output should obviously be present and constant,
I am finding it is either showing just over the target bitrate, red or 0kb/s

Pressing IPTS Monitor on the Portsdown 4 produces eratic results.

What is the shortfall in my set up
Its quite a high end computer I thought!!

Device name Shack
Processor Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz 2.71 GHz
Installed RAM 16.0 GB (15.9 GB usable)
Device ID F304448D-39ED-4243-BF05-38D1080BEDFA
Product ID 00330-51701-84262-AAOEM
System type 64-bit operating system, x64-based processor
Pen and touch No pen or touch input is available for this display
Windows 10


It has built in a NVIDIA Quadro M2000.

If I have to build a new PC for this can members please give me some sugestions and advice
or better still what I might be doing wrong !

TIA

Hi Nick

That CPU was high end, in 2015. While it does have quicksync it is a mobile chip and might struggle, or throttle, but you also said you has an NVIDIA Quadro M2000, this is the Maxwell chipset and also quite old. It does have the H265 encoder but it is limited. It should still work though.

You didn't say if you were running quicksync or Nvidia codecs. I assume you have tried both.

You might find some of the options freestreamcoder expects to use are not implemented. Make sure you have the lastest drivers, that it's not going into power saving mode and the process priority is high. Don't try to run Minitioune at the same time ether.

The rate of progress in CPUs and graphics cards is still astounding, perhaps not to Moore's law but 7 years is a long time.

Hi Mike
All drivers are up to date and thee was nothing else running.
It works sometimes then stops so it looks like new hardware is required.

Looks like I will need to make something.

So Il have to see what ebuyer can put together.

There does not seem to be any where of user experiences with different set ups

Are you sure it is not a network problem? I assume you are using ethernet and not using WiFi?

You didn't say how you configured freestreamcoder - and I assume it is version 2.8, not 2.28

Now is about the right time, but you might want to wait for black friday. Graphics cards are still overpriced but you can use a recent intel CPU. My ASUS Zenbook flip laptop works well but is a bit expensive. You might be able to get last year's model at a good discount. I didn't buy it for DATV so was pleasantly surprised how well it could encode.

Hi Mike the Portsdown is on a wired network but the machine running OBS is on 5gig wifi.
I have ordered a long ethernet cable to connect to the OBS m/c just in case.
If that works I will have to kick myself.

2.28 yes was a typo.
I tried various .settings on the stream corder even just tried to stream one line of text

Cable should be here Monday

Re: IPTS Monitor OBS and freestreamcoder SOLUTION

Post by G1BVI » Sun Oct 16, 2022 10:40 am

Hi Mike

SUCCESS

The previous set up was the Portsdown on the network and the laptop on 5G wifi.
The streamcoder was set to DVB-S2 QPSK sr of 125 and FEC 2/3

yj OBS source was a 4k video.

It either did not work or was so blocky.
I was expecting to see a good picture on the P4.

The solution (as you sugested)
Put laptop on a wired connection.

Now I have it going...
and how stupid noy to realise that the SR setting affects what I see on the pi 4 screen

I went up to a SR of 7000 (not that that will ever be used) but its rock solid.. no stutters eureka

Now to get my head round OBS,

I have ascrolling text with my call sign etc and the date /time..
Need to learn how to drag other screens on top and super impose my live feed .. and................. the list goes on.

Thanks again for your help on this.
I thought running on the 5G wifi would be more than adequate.

Hi Nick,

Glad it works. I would not use a 4k source, that is a lot of pixels to deal with. I would set OBS for full HD 1920x1080 and for the lower rates 720p 1280x720. I also reduce the frame rate, there is a trade off between smoothness and resolution and unless showing sports or fast moving scenes 15FPS is enough for our purposes. Also, you are streaming to the Portsdown, so it helps to have as few as possible changes.

I am not streaming to my Portsdown, I am streaming to the Pluto directly using F5OEO firmware. It works for me but maybe not for beginners. Because I am only sending at 500kb/s, WiFi does work, but I usually have it hard wired for reliability.

Mike
