Question / Help Hardware Encoder Options?

New Member
Good morning,

I am new to the world of streaming and am trying to work things out.

Computer setup: iMac Bootcamp Windows 10, quad-core i7-6700 4GHz, 16gb ram

Inputs: PS4 through Elgato HD60S (Hence the Bootcamp for Windows instead of using the mac version of OBS), Logitech C920 webcam, Focusrite Scarlette 2i2 2nd Gen audio interface with s Rode NT1A mic, stream overlays from StreamElements.

Background: I am an audio engineer who has done nearly nothing with video before.

What works: I can get my stream/recording to function smooth for around 15 minutes on either 1080p or 720p

What doesn't work: After about 15 minutes the CPU overloads and cannot keep up with the encoding. I thought I had a relatively powerful machine, but I guess I was thinking in terms of audio processing and not the strain video processing takes. CPU runs at about 85% and <20fps upon opening OBS.

Suggestions: I'd like to know what hardware encoder options are available to me that will work with OBS to take the strain off of my CPU, and I'd like options in different price-points, and keeping in mind I'm working with an iMac, so I have Thunderbolt/USB3 ports available.


TL;DR - I need hardware encoder options for an iMac with thunderbolt/USB3 connections running Bootcamp Windows 10 and OBS to offload encoding from the CPU.

Thank you so much for helping out a complete noob!

-Leif

Were you connected through rdp to your machine while you created that logfile?
If yes: log on locally. Otherwise OBS will only see the emulated GPU from the rdp session.
If no: install the Intel iGPU video drivers. You seem to have no GPU drivers installed.
The basic renderer is a software emulation of a GPU and takes away much CPU performance if used in connection with OBS. OBS needs accelerated GPU access for video compositing, even if you are not recording some 3D app.
If you installed the iGPU drivers correctly, Quicksync (QSV) will appear as hardware encoder in addition to x264, and if you use Quicksync for recording, CPU usage of OBS will drop to about 5-8%.

Sounds like an thermal Issue. Can you monitor your CPU temperature while trying to record, please?
I'm not positive I have a way to test temp (other than simply saying yes, it runs hotter while OBS is running). It is audibly running harder as well.

I do not know what rdp is, so I am assuming I was not connected via it? This is a recent (last week) install of Windows 10 via bootcamp. I have come across other drivers that were not installed in the process, so it is likely there are ones I have missed as well. I will attempt to install that and report back. Thank you!

Prior to making any other changes I decreased the resolution of some peripherals (specifically the webcam, and the capture card) rather than just scaling them and it reduced the CPU usage, but it is still running at about 40% at 720p 20fps. Here is the log for that

Posting this log before installing the intel drivers to keep a record of what changes resulted in what outcomes.

Ok, I ran dxdiag to find out what gpu I have, it came back with the error "There is a problem with AMD RADEON R9 M395 device. For more information, search for 'graphics device driver error code 39' " as expected. So I found the AMD Radeon R9 M395 Drivers, downloaded, and went to install, the installer gave me the error "Error 173 - AMD Installer cannot continue since AMD graphics hardware was not found."

Dowloaded bootcamp drivers from Apple and it also errored out for the GPU. running a SFC/SCANNOW to see if it's of any help. any ideas?

Update: Mac does some weird stuff with their GPU when it comes to switching, and Boot Camp isn't able to give Windows access to it (from what I can find, there are some options for forcing the switch, but they're beyond my comfort level).

Back to my original question with a follow up, Are there hardware encoder options that I can use via thunderbolt/usb 3? and Will they make a difference considering the GPU issue?

Thanks again everyone!

The only hardware encoders OBS is able to use are the encoders the GPU provides, as long as the corresponding drivers are installed:
- Quicksync on the onboard GPU of most Intel CPUs (your i7-6700k is one of them)
- Nvenc on Nvidia GPUs starting with Kepler architecture (GTX 6xx)
- AMD VCE on AMD GPUs (don't know AMD hardware well, probably all that were manufactured in the past ~5 years)

External devices are not supported. At least not with the Windows version.

If you ask me, you chose the wrong hardware. Usually, it's all set up and configured automatically if you buy a reasonably current Windows desktop PC. Running Windows on mac hardware seems some kind of makeshift. There is a mac version of OBS; doesn't it support the hardware encoder on the AMD GPU or the Intel iGPU of your mac running under macos?

Assuming you want to keep trying to make this work rather than change hardware, you might take a look at what is written here:

https://egpu.io/bootcamp-setup-guide-tb3-macbook-pro/

But as koala posted above, even if you did that, it seems OBS would not use it.

I've gotten the AMD encoder to work when running Windows 10 on Apple hardware, but only by not using Boot Camp and using an EFI installer to install the OS directly.

Thanks for the info. My capture card is the Elgato HD 60S which isn't compatible with the Mac version of OBS. I had everything else available to me (Windows 10, Boot Camp, etc) So I figured I'd attempt OBS with it.

Cheapest fix seems just to be a different capture card that plays well with OBS Mac (I'll search the forum for options). The Elgato Game Capture software that comes with the HD 60 S is quite choppy and not nearly as feature-filled (option to use plugins) as OBS is, which is why I avoided using that as well.

Like I said, I'm just starting to try all this out. Thanks for the help!

Magewell, BlackMagic, AJA. The Elgato Camlink supposedly does not have this same problem, but I have not verified personally and I have been avoiding Elgato since these issues became apparent regarding MacOS and OBS support.
