Hardware Accelerated Video?
Does LMI Central use hardware acceleration for encoding/decoding the video stream, and is the codec published? I can only really speak anecdotally, but I feel like the CPU and GPU usage attribut...
etb thanks for sharing your input with the Community, as others are finding it helpful. 😊
You can find the minimum requirement for Screen blanking here. Otherwise, could you let me know a bit more about what you are thinking on hardware properties/specs that would be more optimized for use with "Blank Screen"?
Hi KateG ,
Thanks for not giving up on me yet - I know that walls of text can be brutal 🙂
I don't mean to overexplain this, because I'm definitely very far from an expert, and I could be wrong about details. But basically I'm drawing the parallel to hardware-accelerated video encoding and decoding.
An example with which we might be more familiar is like watching videos from the internet. If you would pull an old laptop off the shelf and watch a video, you might find that playing the video uses like 25%+ of CPU and kills the battery quickly. A more modern laptop would have a much easier time playing that same video. The reasons the modern laptop would be so much more efficient with playing the video are many, but one big reason is that the modern laptop would likely have hardware-accelerated video decoding such as Intel Quick Sync, or Nvidia NVDEC, etc. As long as the software being used supports using hardware acceleration, and as long as the hardware supports the codec in use, the specialized hardware can be used to very efficiently decode the video (low CPU/GPU usage).
So, tying it back to my question here: is there some particular hardware which can run Screen Blanking notably more efficiently - similar to how hardware with Quick Sync or NVDEC can play videos much more efficiently? Maybe the GoTo developers might say that LMI is using a certain codec, or that Screen Blanking is most optimized for a certain API, and so therefore a particular generation of graphics cards (or newer) would run things notably more efficiently?
Well, Screen Blanking on the Host side seems to have fixed the problem for at least one more laptop.
Still waiting to gain access to the rest.
Hi etb thanks for working with me as well!
From what I've learned so far a graphics card or codec won't apply, Screen Blanking is dependent on the Windows OS, which could be contributing to why it's resource intensive.We are checking with the product team for their input. I will update the thread when I learn more.
Hi KateG ,
May I ask if you ever heard back from the product team about this?
(We are more and more in the market for new computers, so I'd like to optimize as much as possible. I didn't want to follow up earlier, because I know there were a couple instances of bigger deals in the past ~6 weeks.)
