Bug 1417973 - Always use the AMD GPU decoder.

Details 
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171112125346

Steps to reproduce:

Play a 1080p video in Youtube.

W10, CPU Core 2 Quad Q6700, GPU ATI Radeon HD 4600 Series.

Fresh Firefox 57.0 install, tried with all the addons disabled.


Actual results:

The video lags and hangs, CPU usage goes up to 100%.


Expected results:

The video shouldn't lag or hang, just like with any previous version of Firefox and other browsers.
By the way the problem gets worse if I put the mouse pointer on top of the video.
The problem occurs only with 60fps videos.

Thank you.

Did you enable VP9 content by any chance, it's a quite old CPU, it would struggle playing vp9 properly,

Priority: -- → P2
Yes it's a pretty old computer but I've never had any problem with 60 fps videos.

I haven't enabled anything, it's a fresh install of Firefox. I don't know what VP9 is or how to enable it.

Thank you for this...
So it's not what I first thought, your machine doesn't have VP9 support.

I see that you've modified (or something else did) layers.acceleration.force-enabled which is surprising.

My guess is that somehow the hardware decoder isn't available on your box. The ATI 4600 was the first graphic card of this brand to support h264 hardware decoder, but it may not be available under windows 10.
Hpw does playback perform on that box with Chrome or Edge?

The last bit of information that would help, would be to install the media devtools extension (https://addons.mozilla.org/en-US/firefox/addon/devtools-media-panel/) and go into the media tab when one of those videos giving issue is playing. Press the Refresh button and copy/paste the text here.

Thank you for your help in diagnosing the issue.
It was me who modified layers.acceleration.force-enabled trying to troubleshoot the issue, I forgot to set it back, my bad :)

Under Chrome and Edge the 60fps videos play smooth, in fact they also played perfectly under the previous version of Firefox.

Under closer inspection, Edge playback can be smooth but then gets very buggy in parts of the video, Chrome's playback is perfect.

Your machine uses software decoder to decode h.264. That's why your CPU usage is high. Then we need to figure out why you machine doesn't use HW decoder.
My guess is that your graphic cards is too old to be supported by Windows 10 for hardware decoding.
When hardware decoding is disabled, Chrome uses ffmpeg which provides much better performance than Windows software decoder.

Just found something with the media devtools extension, everytime I set the video to 720p 60fps, 1080p or lower reslutions the "Hardware Video Decoding" section is set to "enabled", but everytime I set the video to 1080p 60fps the section is automatically set to "disabled".

So I'm guessing there is something in the code that for some reason disables 1080p 60fps video hardware acceleration. I notice it because I have an old underpowered computer but in other cases people with newer computers don't notice the video is not being accelerated by hardware.

Could that be the issue?

Oh... I remember.
You're falling under this case:

Those graphic cards are known to not work well with 60fps videos. Returning corrupted frames, and sometimes even crashing. We had a bug in 56 and 55 were we incorrectly detected the frame rate, and so the hardware decoder was always used.
It's likely what you are seeing in Edge.

I guess we could add a preference allowing the user to override the safety.
But at this stage, all is working as intended
It would be great if you could add the preference. I have hopes it would work since it works with Chrome and it works for me in previous versions of Firefox.

what's the cpu usage when using chrome?

can you check if it's using the hardware decoder?

While a video is playing go to chrome://media-internals/

Click the button that's captioned with 'blob' and the video URL. In the table below, look for the value of video_decoder. If it says GpuVideoDecoder, Chrome is using the GPU.
The CPU usage using Chrome is between 45% and 90%

The video_decoder value is "VpxVideoDecoder"

Here is the full output just in case there's something relevant:

render_id: 22
player_id: 36

So you're using vp9 there.
You can make Firefox behave like Chrome by setting media.mediasource.webm.enabled to true. Performance should be better even than Chrome.

But I'd be more interested to see if Chrome behaves with h264 and the hardware decoder.
Thank you that did it, it's so much better now.

I tried a clip from here http://www.h264info.com/clips.html and Chrome works excellent with h264 videos, low CPU and low GPU. 

If you need me to do some test with Chome just ask me.
Including 60fps 1080p H264 videos?
The video I tried was 30fps. If you point me to an 60fps sample I can test it.
here is one:
http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_60fps_normal.mp4

If you want to play with various content (definitions, frame rates, codec etc)
http://bbb3d.renderfarming.net/download.html
Ok, I tried the first video, works better in Chrome, the CPU goes between 20% and 40%, the GPU stays at 26%, the video pauses every few seconds but for less than a second.

Firefox is worse because the video pauses a lot and for many seconds, the CPU goes from 20% to 100%, when it reaches 100% it pauses, then goes down to 20% and up again, then pauses again. The GPU stays a 0% and once in a while goes up to 41% max.

I'd say it's only watchable in Chrome if you don't mind the constant pausing that lasts less than a second but for many people would also be unwatchable.

My question was about weither Chrome uses the hardware decoder for that video...

To check using the instructions provided in comment 14.

Ok, I'll remove this limitation of the hardware decoder... it never made much sense to me.

thanks for your help.

Bug 1417973 - Always use the AMD GPU decoder.

https://reviewboard.mozilla.org/r/202172/#review207536

Code wise this seems fine.

Intent wise, this is your call, but when I wrote this code, we were doing significantly better in software for the machines that I tested on these videos.

It's possible that this has changed (nv12? d3d11 decoder?), or maybe you're testing with different configurations (I used one of the QA machines in the Toronto office).

Not saying you shouldn't do this, but just something to keep an eye on.
Attachment #8931081 - Flags: review?(matt.woodrow) → review+
Yeah, that's why I just didn't remove the code and set a pref.
In this case it's possible to be 32bits vs 64bits. I had that processor a while back and it was significantly worse doing 32 bits code than 64. That was even more telling using ffmpeg. 

Could you test with this installer?
