High GPU usage on video playback

Reported by sumon.ah...@gmail.com, Jan 15 2018 
UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36

Example URL:
https://www.twitch.tv/videos/218282245

Steps to reproduce the problem:
1. Go to the link: https://www.twitch.tv/videos/218282245
2. Chrome should use only discrete GPU
3. It does not use HW acceleration properly.Seems like chrome always use double the GPU usage needed to be used.Chrome always copy its content to Desktop Window Manager resuling in unnecessary gpu usage.

What is the expected behavior?
Chrome should use hardware acceleration of descrete GPU

What went wrong?
Chrome is not using hardware acceleration properly.I do not see chrome using ,"Video Decoding"/"Video Processing" like edge.

Did this work before? N/A 

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes

Please compare the 2 images.No matter which GPU i use,chrome always tries to copy its buffer back to DWM resulting in GPU overhead.I tried using Intel GPU/Discrete GPU.I also tried the *overlays* flags so chrome directly renders videos to Memory ,but seems like something is not working?

Looks like chrome uses "Video Decode" properly only when the video is fullscreen and there is other UI.Please look at the following screenshot and observe difference in CPU/GPU usage.
NOTE: Similiar behaviour is observed even if i choose dGPU.Looks like chrome handles video differently(or efficiently) when its fullscreen + no other UI elements.

sumon.ahmed511@ Thanks for the issue.

Tested this issue on Windows 10 on the latest Canary 65.0.3325.0 and Stable 63.0.3239.132 by following the below steps.

1. Launched Chrome and navigated to the given link https://www.twitch.tv/videos/218282245.
2. Launched Windows task Manager and cannot observe the option GPU engine to test this issue.
Attached is the screen shot for reference.

Below are the GPU details :
Operating system : Windows NT 10.0.15063
GL_VENDOR	 : Google Inc.
GL_RENDERER	 : ANGLE (NVIDIA NVS 315 Direct3D11 vs_5_0 ps_5_0)
GL_VERSION	 : OpenGL ES 3.0 (ANGLE 2.1.0.2ff870db3a3b)

Probably GPU Engine option may be seen on the latest version of Windows 10. 
Hence adding TE-NeedsTriageFromHYD label and requesting someone from In-house team to please look into this issue and help in further triaging. 

Thanks..

@susanjun GPU tab is introduced in fall creators update.You can enable GPU monitoring in task manager by right clicking and ticking.

Alternatively you can use other GPU monitoring utility like GPU-Z to monitor gpu usage.but Windows task manager gives you precise GPU usage categorized by process.

Comment 5 by sumon.ah...@gmail.com, Jan 21 2018 

why is this bug being abandoned like this? anyone wanna comment on this double gpu usage.

Comment 6 by dalecur...@chromium.org, Jan 22 2018 

Can you try Chrome canary 65.0.3317.0+? I recently updated our implementation there after some information from Microsoft came back,  issue 728296 .

Comment 7 by sumon.ah...@gmail.com, Jan 22 2018 

looks like its even worse on canary.please look at screenshot.I've run with following flags:
"C:\Users\tiger\AppData\Local\Google\Chrome SxS\Application\chrome.exe" --enable-hardware-overlays --enable-direct-composition-layers --enable-features=DirectCompositionUnderlays,DirectCompositionComplexOverlays --flag-switches-begin --enable-zero-copy --force-color-profile=srgb --flag-switches-end

Comment 8 by sumon.ah...@gmail.com, Jan 22 2018 

Chrome 63/canary 65 works works properly when the video is Fullscreen+ No player UI + the following flags are set:

--enable-hardware-overlays --enable-direct-composition-layers


Missing any of the above points results in High GPU usage for desktop manager and chrome(im talking about 40% each) when watching videos on youtube/twitch.

anybody in composition team can take a look?

Hmm, those flags should be on by default if your drivers aren't blacklisted. What does chrome://gpu say on Chrome Canary? +liberato

Comment 11 by sumon.ah...@gmail.com, Jan 31 2018 

Without those flags in canary, about:gpu reports

Supports overlays	false

with those flags:

Supports overlays	true


I've attached full gpu reports.

And even with those flags , chrome use GPU video decode properly only when Video is Fullscreen+ no player ui/annotation.

Comment 12 by dalecur...@chromium.org, Jan 31 2018 

Hmm, your device supports direct composition so it means the overlays are still being disabled somewhere in this path:

https://cs.chromium.org/chromium/src/gpu/ipc/service/direct_composition_surface_win.cc?l=94

I'm not sure why though.

Comment 13 by dalecur...@chromium.org, Jan 31 2018 

I'll create a debug build and share it with you tomorrow for testing which should let us know where in that path we're bailing out.

Comment 14 by sumon.ah...@gmail.com, Jan 31 2018 

@dalecue sure, i can test your build and give you report.also please note that its an Optimus device ( Intel HD 530+ GTX 960M) with latest driver from intel and nvidia.

I usually use High performance(dGPU) for chrome but this behaviour is same even with iGPU.

Comment 15 by dalecur...@chromium.org, Feb 2 2018 

http://storage.googleapis.com/dalecurtis/chrome-display-logs.zip

Run it from the command line with chrome.exe --user-data-dir=.data and then attach the output of chrome://gpu which should have the logs we need.

I've run it with nvidia and intel.looks like overlay supported by default with intel gpu.So i've run a twitch 1080p video on chrome with iGPU and  edge.Chrome is using 70% GPU in total whereas edge is using 20%.Lots of extra overhear comes frfom DWM.

Hmm interesting! With the nvidia card, the OS is telling us "DXGI_ERROR_DEVICE_REMOVED" when we try enumerate it's outputs - presumably because it's still trying to use enumerate the integrated graphics card.

I'd expect we would be attempting direct composition with the discrete card.  +sunnyps, angle folks for commentary on which device should be returned by gl::QueryD3D11DeviceObjectFromANGLE() when discrete gpu is forced.

Thanks!!

Comment 22 by sunn...@chromium.org, Mar 15 2018

Labels: -Needs-Feedback
I need to look into this. Maybe all we need to do is enumerate outputs on all adapters instead of failing on the active adapter. It's possible this system uses the integrated GPU for scanout always. Still the error DXGI_ERROR_DEVICE_REMOVED doesn't make sense.

I'm going to try reproducing this on a Razer Blade.

I've run the chrome-display-log version in another laptop.i've attached the chrome://gpu report for both Intregated and dGPU output.

Status: WontFix (was: Assigned)
Got around to testing on a Razer Blade. The GPU we choose depends on the preferred GPU configured in Nvidia control panel, and the custom profile for chrome.exe if there is one.

If I set discrete GPU as preferred (default on my system), the DXGI adapter says that overlays are not supported, but if I set integrated GPU as preferred, the DXGI adapter says (scaled) overlays are supported.

I even tried enumerating all adapters, and all their outputs to check if overlays are supported on any output, and the answer is no when the Nvidia GPU is selected.

Forcing overlays on lowers power usage for fullscreen because the video's layer skips DWM and flips directly to the display in that case. Without overlays, we blit the video to Chrome's backbuffer, and that has a cost.

So from Chrome side we can solve this if we disregard the user's configuration, and choose integrated over discrete GPU. So I'm going to close this as WontFix, because of the workaround of using Nvidia control panel to choose integrated GPU for Chrome.

The DXGI_ERROR_DEVICE_REMOVED is probably a red herring.

@25 , Even with intregated GPU, why does not chrome skip DWM  when not playing in fullscreen ? Is that normal by design? because i have seen different approach for Edge and Firefox.They both skip DWM GPU usage whether youtube is fullscreen or not.
