HTPC Credentials - Local Media Playback and Video Processing

Evaluation of local media playback and video processing is done by playing back files encompassing a range of relevant codecs, containers, resolutions, and frame rates. A note of the efficiency is also made by tracking GPU usage and power consumption of the system at the wall. Users have their own preference for the playback software / decoder / renderer, and our aim is to have numbers representative of commonly encountered scenarios. Towards this, we played back the test streams using the following combinations:

  • MPC-HC x64 1.8.5 + LAV Video Decoder (DXVA2 Native) + Enhanced Video Renderer - Custom Presenter (EVR-CP)
  • MPC-HC x64 1.8.5 + LAV Video Decoder (D3D11) + madVR 0.92.17 (DXVA-Focused)
  • MPC-HC x64 1.8.5 + LAV Video Decoder (D3D11) + madVR 0.92.17 (Lanczos-Focused)
  • VLC 3.0.8
  • Kodi 18.5

The thirteen test streams (each of 90s duration) were played back from the local disk with an interval of 30 seconds in-between. Various metrics including GPU power consumption and at-wall power consumption were recorded during the course of this playback. Prior to looking at the metrics, a quick summary of the decoding capabilities of the Intel UHD Graphics is useful to have for context.

The Intel UHD Graphics GPU is no different from the GPUs in the Bean Canyon and Baby Canyon NUCs as far as video decoding capabilities are concerned. We have hardware acceleration for all common codecs including VP9 Profile 2.

All our playback tests were done with the desktop HDR setting turned on. It is possible for certain system configurations to have madVR automatically turn on/off the HDR capabilities prior to the playback of a HDR video, but, we didn't take advantage of that in our testing.

VLC and Kodi

VLC is the playback software of choice for the average PC user who doesn't need a ten-foot UI. Its install-and-play simplicity has made it extremely popular. Over the years, the software has gained the ability to take advantage of various hardware acceleration options. Kodi, on the other hand, has a ten-foot UI making it the perfect open-source software for dedicated HTPCs. Support for add-ons make it very extensible and capable of customization. We played back our test files using the default VLC and Kodi configurations, and recorded the following metrics.

Video Playback Efficiency - VLC and Kodi

VLC doesn't seem to take advantage of VP9 Profile 2 hardware acceleration, while Kodi is able to play back all streams without any hiccups.

MPC-HC

MPC-HC offers an easy way to test out different combinations of decoders and renderers. The first configuration we evaluated is the default post-install scenario, with only the in-built LAV Video Decoder forced to DXVA2 Native mode. Two additional passes were done with different madVR configurations. In the first one (DXVA-focused), we configured madVR to make use of the DXVA-accelerated video processing capabilities as much as possible. In the second (Lanczos-focused), the image scaling algorithms were set to 'Lanczos 3-tap, with anti-ringing checked'. Chroma upscaling was configured to be 'BiCubic 75 with anti-ringing checked' in both cases. The metrics collected during the playback of the test files using the above three configurations are presented below.

Video Playback Efficiency - MPC-HC with EVR-CP and madVR

LAV Filters with EVR-CP is able to play back all streams without dropped frames, but madVR is a different story. Almost all streams 1080p and higher see varying levels of significant spikes in power consumption pointing to the decode and display chain struggling to keep up with the required presentation frame rate. Given that the GPU is weaker than the one in Bean Canyon, this is not a surprise. Overall, the Frost Canyon NUC is acceptable for a vanilla decode and playback device without extensive video post-processing.

    Did you notice - I made no mention of Intel in my comment - you falsely assume bias - which is normal in these types of forums.

    "this machine" is a computer with an Intel processor.
  • Korguz - Monday, March 2, 2020 - link

    note falsely assuming nothing, it has an intel product inside, and you defended/made excuses for it.
  • MamiyaOtaru - Tuesday, March 3, 2020 - link

    No one has to assume anything about your bias. You have a posting history. I know you'd like to pretend that your comment that "made no mention of Intel" was your first comment ever and there's no context or anything that could inform readers about your position
  • MamiyaOtaru - Tuesday, March 3, 2020 - link

    not that your point is wrong to be fair. but no one is surprised you'd make one in defense of Intel, or that the person making such a comment would be you
  • HStewart - Tuesday, March 3, 2020 - link

    I think the bigger concern is why are so many offended by it - do you really believe that attitude will help bring people to AMD or other product.
  • Korguz - Wednesday, March 4, 2020 - link

    let me ask you the same question, do you really believe praising, defending, and making excuses for intel will being people to continue to buy intel ?
  • HStewart - Tuesday, March 3, 2020 - link

    Just because my posting history lends toward Intel on PC products - doe snot mean that I used other products - like Samsung Android and such. Maybe it more I just I don't like AMD - a lot because of personal experience with AMD in past - actually mostly on video side, Only trick with non-real Intel 386 cpu in my first computer. That gave me bad feeling since.

    no hstewart.. the issue is, you defend and make excuses for intel no matter what. even if amd clearly is the better product, you still praise intel, and bash amd in some way. and you almost never provide any proof of your claims towards intel. you have a known intel bias, and are known to be an intel fannoy, plain and simple.
  • paulemannsen - Wednesday, March 4, 2020 - link

    Your posting history is the biggest pile of shame ever seen in Anandtechs comment section. You are single handedly responsible for half of the downfall of a ones thriving community. The audacity of you, still thinking anything out of your mouth could be a benefit to society and not be downright poisonous is 110% delusional.
