Unpredicatable behavior when chosing sources.

[andrewfenner]

I have been posting each week on my progress (or lack of it) with this problem and no-one has replied so either I am not very good at explaining it, or I have flummoxed this community!

In summary:

• I have a hall set up with three webcams and then a camera and laptop via USB/HDMI capture dongle, So five sources in total appearing as options of either “webcam” (x 3) or “USB 3 Capture device” (x 2)
• I am using a Intel® NUC Kit NUC5i5RYH running Windows 10.
• It only has 4 USB 3.0 ports on the machine, so initially I had all the webcams/USB adapters running into a RSHTECH powered USB 3 hub, plugged into one of the ports.
• NB: When I connect this set up to a Mac Air running OBS it all works fine.
• When I connect it to my windows machine, I somethings see some of the webcams, sometimes I don’t, if I relaunch OBS I sometimes see different cameras to the ones that I saw before. Basically, very flaky and unreliable. The most I have ever managed to see is 5 of the sources.
• Last week I posted the log and when I looked at it (I am new to logs) I noticed the warning “DShow: Run failed (0x800705AA): Insufficient system resources exist to complete the requested service.” I googled this, which directed me back to this forum, and I saw this was a common problem and one way to fix it was to not use the hub. Alas 5 sources into 4 ports doesn’t go, but I have tried numerous combinations of different cameras plugged into different ports.
• The net result is still the same as above; totally unpredictable.
• I have posted the first part log below (it just repeatd thereafter) and attached the log. Is it a case that my computer is simply not up to the task, or is it something else that I can do?
• Any help greatly appreciated.

• ...snip... Is it a case that my computer is simply not up to the task, or is it something else that I can do?

16:54:23.571: CPU Name: Intel(R) Core(TM) i5-5250U CPU @ 1.60GHz [2c/4t]

the U in the CPU model indicates ultra-low power for battery life, whereas you want to do the opposite with the computationally demanding task of real-time video encoding. Can a PC do what you are asking? Yes.
BUT - that is 7 generation old [Q1 2015] low-end laptop CPU - most likely it isn't up to what you are tasking it with. You could lower camera resolutions, etc to fit within performance envelope of that system.. but whether that will meet your needs is another question

Look up USB Root Hub overload in this forum for suggestions on work-arounds. *If* the NUC didn't go cheap with a single USB Root Hub (I'll let you research this), then a combination of using the hub and direct connect would be your best bet. Just curious, I'm assuming you connected USB Hub to Mac Air on a USB3 port, right? Which speed USB3? and what speed is the USB Hub capable of? I just checked and that 2015 NUC has 4 external USB3.0 ports, so definitely use them. I'd test with keyboard and mouse on the external USB hub
And make sure you have optimized the OS

I recommend monitoring hardware resource (CPU, GPU, RAM, etc) utilization [for ex. using Task manager’s Performance tab and/or Resource Monitor] to see if your system is being maxed out with your settings (which I'm sure it is)

 

[andrewfenner]

Thanks for taking the time to reply Lawrence. Thanks for confirming what I thought. To answer your questions:

- This is hub https://www.rshtech.com/products/7-ports-aluminum-usb-30-data-hub-with-12v-2a-power-adapterrsh-a37s I'm afraid I have no idea what it is capable of. I did use USB 3 ports, on my mac, but again, not sure which speed. This is what the system report says:

SB 3.0 Bus:

Host Controller Driver: AppleUSBXHCIWPT
PCI Device ID: 0x9cb1
PCI Revision ID: 0x0003
PCI Vendor ID: 0x8086


BRCM20702 Hub:

Product ID: 0x4500
Vendor ID: 0x0a5c (Broadcom Corp.)
Version: 1.00
Manufacturer: Apple Inc.
Location ID: 0x14300000

Not sure if that helps!

3 Questions from me now:

1 - "And make sure you have optimized the OS" - How do I do this and what do I set it to?
2 - I have noticed people in other post say turn "Windows 10 Gaming Features: Game DVR: On" to "off". Would you recommned that?
3 - When I use Zoom, all cameras appear no problem, but I have no idea if Zoom requires a lot less processing power than OBS.

I will go and look up USB Root Hub overload now. Thanks again.

 

[Lawrence_SoCal]

Sorry, OS optimization is a whole art unto itself, and WAY outside the realm of an OBS discussion forum. A good start would be to simply make sure eye candy turned off, unnecessary processes not running, etc. If you are not technical, expect to spend some time finding out real answers (lots of really BAD advice on YouTube and elsewhere on this topic by people with no clue what they are talking about ...or hoping to mess people's systems up and get consulting work, or ?? ) or go get someone who truly knows there way around the OS. Then again, if you are using a 6+ old NUC, I'm guessing you don't have the funds for such??

Yes, I'd turn off LOTS of Win10 features, including the Game ones. And MANY others. But that comes as part of personal preferences and over 25+ yrs professional IT experience (and my personal PC experience going even further back to 8086 and PC-DOS v1.25 days)
On a system of your age, and NOT having a dedicated GPU to turn over encoding duties to, you are likely to need to make sure you are using optimal QuickSync settings (no I don't know what they are, much less for your system) and possibly running OBS with Admin privilege's (ie local account in Adminstrator's group)

Correct - I'd expect Zoom to use a LOT less resources than OBS. Even more so as Zoom is likely only using a single camera at a time, not processing all 3 at once

 

[andrewfenner]

Thanks Lawrence. I have found some really useful advice on USB overload on this forum so will crack on. I actuall think lowereing the resolution os probably the best fiest choice. We are only streaiming to Zoom to people watching in laptops, so I think I can afford to drop that from full HD in the first instance. Thanks a lot for all you advice.

 

[Lawrence_SoCal]

This was just posted

1) Download USB Tree View from https://www.softpedia.com/get/System/System-Info/USB-Device-Tree-Viewer.shtml

Go to the post link to see more details

 

[andrewfenner]

Thanks. I downloaded that from another post last night.

This morning I replugged my USB's (to make sure the 2 capture cards were not sharing the same USB bus); reduced the resolution on all the cams to 720p; turned the output resolution down turned off games mode; made sure there was nothing being loaded up at start up and changed the encoder from x264 to Quck Synch and it now all works, so thanks for that.

Saying that, I ran task manager and wached the CPU usage and at some points it was up 100% when I was streaming a camera and a feed from YouTube and a camera similtaneously to Zoom. But really, the chances of us doing this on a regular basis are rare (if any).

The reason we have such a low powered PC is that is was donated as we just needed something that would run Zoom, which is does beautifully. I use OBS at home on 2009 MacPro no problems so I thought I would give it a go on the PC. I didn't realise how CPU hungry OBS was ot how low powered the PC was. I will probably continue playing with Windows settings and OBS settings to see if I can reduce the CPU usage further. Thanks again for all your help.

 

[Lawrence_SoCal]

It isn't OBS... any real-time video compositing solution is going to have similar resource demands
An analogy is driving 150+mph.... I don't car which vehicle you have, it takes LOTS of horsepower. In this case, yes that is a lower-end CPU. Use any CPU general benchmark rating to see how it compares

 

[andrewfenner]

Will do. Thanks for all the advice. Very much appreciated.
