Comment #1 on issue 442047 by ***@googlemail.com: Hardware
acceleration doesn't work on Youtube Webm / VP9
https://code.google.com/p/chromium/issues/detail?id=442047

Network has 13Mbit/s download. Could be better but with a few seconds
buffering, this is not the issue here.

Firefox doesn't allow to use VP9. The same goes for IE11. If I start the
same Video there, I have Flash or H.264 which is running smooth but 720p
max.

VLC and XBMC can handle Youtube videos without any issues and with hardware
acceleration in 1080p. But I'm not sure which codec they use.

It's a Lenovo X121e Subnotebook with an AMD e-450 APU (integrated GPU is
the HD 6320)

Windows has all latest updates and drivers installed. New AMD Omega driver
is used, but the issue took also part with all the old Catalyst drivers.

Any ideas?

Kind Regards,
Tabis

https://code.google.com/p/chromium/issues/detail?id=442047

Re: c#1 VP9 videos are not hardware accelerated yet. We have not seen this
AMD CPU before and as a result have not profiled it on the CPU yet.

Firefox supports VP9 decode, but has not completed its MSE support yet and
hence doesn't receive VP9 videos. IE 11 doesn't support VP9 decode anyway.

Can you tell me if you see this issue in the following videos as well?
Thanks.

Thank you.

https://code.google.com/p/chromium/issues/detail?id=442047

My CPU has just not enough performance to calculate 1080p videos alone. So
your answer makes perfect sense for me.

Chrome results
1st video is VP9, it's stuttering as soon as it switches to HD. CPU is at
100%.
2nd video is also VP9, exactly the same.
3rd video is H.264. ***@24fps is shown at the nerd statistics. Perfect
playback, no stuttering, CPU load is approx. 50%.

Firefox results
1st Video is H.264. 720p is the max resolution. running smooth.
2nd Video is H.264. 720p is the max resolution. running smooth.
3rd Video is H.264. 720p is the max resolution. running smooth.
CPU load is around 20% at all three videos

IE11 results with flash
1st is Flash with 1080p running smooth. 40% CPU load. hardware acceleration
is working fine with flash.
2nd same like 1st
3rd same like 1st

IE11 results (turned to HTML5)
1st video is H.264 720p max. smooth and with 30% cpu load
2nd same like 1st
3rd same like 1st

please note, chrome was active in the background during tests of Firefox
and IE. Means CPU load could be less for stand alone tests.

I think it's bad that obviously H.264 high resolution is available (Chrome
result #3) but only for Chrome... :-(


I'm not sure whether I've got your first point. Is VP9 NOT accelerated on
any plattform or just on the less known like mine?
When will Chrome be able to use hardware acceleration on my system?

Do you need any further information about my AMD APU? Screenshots or
anything? Just tell me :-)

Many thanks,
Tabis

https://code.google.com/p/chromium/issues/detail?id=442047

Hello all,

This is my first post on this website, Sorry if I am not supposed to talk
here, but I have a system similar to Tabis' machine and I thought it might
be interesting to hear from another user. My machine is also a APU based
system running an AMD E-350, however instead of using the onboard ATI
HD6310 graphics chip it comes with, I am using a PCI-E Nvidia 9600gt 512mb
with latest drivers.

CPU: AMD E350 APU 1.6Ghz DualCore
Ram: 8gb DDR3
HDD: 320GB 7200rpm, 320GB 7200rpm
Graphics: Nvidia 9600GT 512mb x16 pcie (Running on a x4 pcie lane)
OS: Windows 10 Preview Build 9879
Internet: 16mbit down\2mbit up

I have tested several different high definition video's on IE11, Chrome,
Chromium (under ZorinOS on same machine) and firefox.

IE11 can play up to the following smoothly at about 50%CPU
1080p at 30fps
720p at 60fps

Chrome can play up to following at around 80-100% CPU
480p at 30fps

Firefox can run up to the following at 60% CPU
1080p at 30fps
60fps was not an option

VP9 is nice on higher power machines, but for a lot of lower power machines
it doesn't work out too well it seems. Even with a 9600gt Chrome\Chromium
will not utilize it. Similar results were found using the onboard HD6310
graphics as well. I just want the extra power for gaming with the 9600gt.

Is there a way to force flash on Chrome\Chromium until hardware
acceleration of VP9 is available?

Thanks
TailsFurse

@Tailsfurse: Search for HTML5 Youtube with google. Most probably as first
result, you will find a youtube webpage, where google shows what your
Browser is supporting and direct below you can choose between HTML5 and
Flash. From now on youtube will follow your chosen option. Unfortunately
most Flash videos are just 720p even if in HTML5 there is a 1080p version
available.

Good Luck ;)

So it looks like chrome is selecting vp9 over h264 on devices which support
the later in HW. If I go back to IE, then I get great CPU usage and smooth
video.

I'd like a way to just turn off vp9.

Use Disable Youtube™ HTML5 Player in Chrome. Also change used flash plugin
in chrome://plugins/ settings to original adobe one. By default it uses
crappy pepflashplayer.dll in which I have pixelated videos. The only
problem for me is 60fps videos, which flash player doesn't support.

Well he said that H264 videos would be GPU decoded and VP9 videos would not.
His problem is more a Youtube problem, it serves unplayble VP9 videos where
H264 videos would be possible.

It's just a matter of time that AMD would propose some openCL VP9 decoding
and this kind of problem would be solved.

almost always not system hardware not capable handling 1080p. It seems to
be AMD driver not working with youtube/flash or html5. Hence for me
accelerated decoding only up to 720p. And 1080p will kill the cpu.

But youtube/flash 1080p acceleration works perfectly on IE11, 10% cpu. So
it backs to chrome/firefox/opera.

https://code.google.com/p/chromium/issues/detail?id=442047

The issue is not the computer being unable to play back 1080p videos. The
issue is the computer being unable to play 1080p vp9 videos. I started
investigating this issue yesterday when I tried to watch a 1080p60 video on
youtube (bUMMP2fY0fc). I opened it in Chrome because it's the only browser
that seems to get served 60 fps videos. Around the 5:30 mark the video
becomes a slideshow with the frame rate more accurately described
with "seconds per frame" that the other way around.

In the end I downloaded the h.264 and vp9 versions of the video off Youtube
and tried playing them back locally, using MPC-HC. MPC-HC plays the h.264
file smoothly with cpu hovering around 5%. With the vp9 file cpu load is
somewhere around 80% and the video stutters constantly.

This is on an AMD Phenom II X4 955 cpu and a Geforce gtx 660 gpu. So not a
very new or powerful machine. However, if it can play a 1080p60 h.264 video
without any problems and a very low cpu load, the "next generation" codec
should not cause this much issues. I could accept cpu load being at 10% or
20% compared to the 5% of h.264.

I read on http://code.google.com/p/chromium/issues/detail?id=451954 that
vp9 does not have HW acceleration and apparently it is not even coming, the
planned improvements will apply on the software decoder.

As an alternative solution, if the codec is unusable in practice, it would
be nice to be able to disable it somehow so that sites like Youtube would
serve me video I can actually watch.

@10 "It's just a matter of time that AMD would propose some openCL VP9
decoding and this kind of problem would be solved. "

Sorry about my ignorance, but could you say why AMD should make/propose
openCL decoder for VP9. It is google's codec and problem is running it on
google's browser. OpenCL is open for anyone to use and hardware independent
(same solution should work in both nv and amd devices)... so why doesn't
google make their own openCL acceleration for their browser, and give out
openCL package for other browser makers to implement?
