Please provide the full output of about:support, including the modified preferences.

I find it suspicious that your machine be enabling VP9 to start with.

Leman,
Can you also help use mozregression[1] for the possible change?
Thanks.

If that were true, VP9 would have been a roadblock a long time ago. My machine has no issues decoding VP9 up to 4K30p with 28-33% CPU usage on good builds. Frames usually start dropping at 4k60p. Although, Chrome Canary seems to be using black magic to keep those frame drops to a minimum. Bad Nightly builds use over double the CPU power for the same content at every quality level.

Indeed, VP9 benchmarks dropped from 219 on my Dell XPS 15 to only 153 (after disabling the VP9 hardware decoder)

Should have bumped the VP9 benchmark version up to force re-running it...

Could you please confirm that the problem is fixed for you?

thank you

Comment 18

[Jean-Yves Avenard [:jya]]

Today's benchmark result is 239fps with the software decoder (so even better than before) and 206fps with the HW decoder...

Comment 19

[Leman Bennett [Omega]]

I can confirm. No frame drops. Even 4k60p is performing a little better.

[Jean-Yves Avenard [:jya]]

Great to know. Thank you

Comment 22

[Paul Oiegas [:poiegas], PM for (Ecosystem QA, Services QA, WebCompat QA, Ads QA, and Solo QA teams)]

Hey guys, it seems that something broke in Nightly 58 after this issue was fixed. 

In the last few days, when I fast forward my YouTube videos, they break showing the default player error screen.
Tried to find the cause but I couldn't manage to reproduce the issue on a new profile. Then, I've tried to disable all mu add-ons manually from my profile and retied, but it still failed. Strangely, by entering in safe mode, the issue was no longer present. So I have tried to find the regression range with mozregression by using my profile. After reaching the end of it, this issue popped out.

But the fact that this was only reproducing with my profile, still bugged me. So I've tried to install all my add-ons one by one on a new profile, to see if anything breaks. Luckily the first one installed broke my playback again, I'm talking by AdBlock for Firefox (https://addons.mozilla.org/en-US/firefox/addon/adblock-for-firefox/).
Afterwards I've also tried with Adblock Plus and the same scenario occurred.

A lot of people use adblockers these days, so I assume this is an easily encountered regression. Since I'm not seeing any recent bug logged about this regression after a quick search, I'll reopen this one for further investigations. Jean-Yves, can you please take a look again at this?

Comment 23

[Jean-Yves Avenard [:jya]]

Please open a new bug, the symptoms you describe have nothing to do with frames being dropped due to lack of speed.

Comment 24

[Paul Oiegas [:poiegas], PM for (Ecosystem QA, Services QA, WebCompat QA, Ads QA, and Solo QA teams)]

I will as soon as I investigate a bit more. I cannot reproduce it at work but I can regularly reproduce it on my home PC. It may be something related to the hardware + software combination. Will dig more and file an issue afterwards.

Comment 25

[Jean-Yves Avenard [:jya]]

And please post your about:support , you may not even run with VP9, which would totally remove any link to the VP9 decoder.

I believe you're seeing bug 1409176

Comment 27

[Paul Oiegas [:poiegas], PM for (Ecosystem QA, Services QA, WebCompat QA, Ads QA, and Solo QA teams)]

To be honest, I have tried again to find the regression window on my machine and I've seen a second behavior while doing that.
1. If I follow the normal behavior, seeking twice the video in order to crash, then it leads me straight to this bug again.
2. While following the normal behavior observed, mozregression throws me after a while a build where if I seek just once it crashes the YT video.

After observing this, I've decided to make another parallel regression window search. Indeed, it led to bug 1409176, but I'm still not convinced that the issue found on second search is the right one. I'm saying this because when the issue occurs from the first seek, after a page refresh, I cannot reproduce it anymore. So this happens only once at the first seek attempt and after YT videos can be correctly seek.

As I've told you on Friday on our IRC discussion, if I alter the "media.benchmark.vp9.threshold" value to be at least 1 unit above the measured "media.benchmark.vp9.fps" value, the issue no longer occurs. The same thing happens if I set "media.mediasource.enabled" to "false" 

Also, I have figured out that the issue has nothing to do with the adblocker extension. It happens on a clean new profile, but only after it measures the PC performances. So first time when you start a profile and watch a YT video, it measures the fps. In this state the issue does not occur when seeking. But if I refresh the video page and seek twice, the issue occurs at 100% rate.

Here is a screen recording of the issue: https://goo.gl/A4gU8V.
Also, here is the about:support page content, if it helps https://goo.gl/F3d8P7.

Comment 28

[Jean-Yves Avenard [:jya]]

As discussed on IRC, your machine is fast enough to get VP9. It also has a nvidia 1070 which has a VP9 hardware decoder.
As such, on your machine you will never enter the code path changed by this bug: you don't use the software decoder (ffvp9), you use the Microsoft VP9 MFT.

Changing the preferences like you do is never going to change that.

The preferences you're changing (media.benchmark.vp9.*) aren't even read because you have set media.mediasource.webm.enabled to true (as per our discussion)

That bug 1409176 introduced a regression on windows, now that makes sense. You are using that code path (windows hardware decoder).

If on a clear profile you set, media.benchmark.vp9.threshold to a value of 1 below the value of media.benchmark.vp9.fps then this would disable VP9 altogether, and you're know using the H264 decoder
If you set "media.mediasource.enabled" to false, then you won't get VP9 either (VP9 is only used with MSE)

(you can see which decoder is in use by right clicking on the youtube player window and selecting "stats for nerds").

What you report has nothing to do with the VP9 software decoder.

Please open a new bug, we shouldn't cloud this bug with irrelevant data. Especially as this bug is closed.

We can continue discussing your issue in the new bug.
