Harware accelaration for vp9 not working

[SM17]

I have I5- 4200U processor with intelHD graphics 4400 & AMD 8670M onboard

In chrome, intel GPU was blacklisted as hardware acceleration not supported.

So i did override settings to force enable it, also enabled zero copy rasterization & nativegpumemory buffers to hardware accelerated

but out of luck....perfomance is little better but still skipping frames on 1080p60fps video..earlier before tweaking...it used to skip 40% frames...but now its skipping 10% frames

then i observed while playing vp9 video which decoder is using typed in chrome://media-internals and it was showing vpx decoder

few random videos play on youtube in h264.mp4 , At that time decoder shows GPU decoder but out of luck for vp9

While playing vp9 video at 1080p 60fps...CPU usage skyrockets to 88% & at normal 1080p video around 50% .....to my surprise..gpu is also ytaking stress at around 25% though vp9 was software decoding

any workaround is highly appreciated...thanks ....will be active here...running latest drivers btw

I've also checked by dxva checker, there is no sign of VP9 support...is my gpu not supported 😞 or its any driver bug ???

Hello sreekantt,

I understand you are having performance issues when playing VP9 videos. Let me apologize for any inconvenience this issue may be causing to you. VP9 video decoding is supported on 6th Generation Intel® Core™ processors and 7th Generation Intel® Core™ processors via hardware. On older graphics controllers the decoding is done via software by the CPU itself. It might be expected you may get higher CPU usage on your i5- 4200U processor while decoding VP9 videos. The following datasheets will provide more information about VP9 support: 7th Generation Intel® Core™ processors http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/7th-gen-core-family-desktop-s-processor-lines-datasheet-vol-1.pdf http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/7th-gen-core-family-desktop-s-processor-lines-datasheet-vol-1.pdf 6th Generation Intel® Core™ processors http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/desktop-6th-gen-core-family-datasheet-vol-1.pdf http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/desktop-6th-gen-core-family-datasheet-vol-1.pdf 4th Generation Intel® Core™ processors http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/4th-gen-core-family-desktop-vol-1-datasheet.pdf http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/4th-gen-core-family-desktop-vol-1-datasheet.pdf Let me know if you have or not any other inquiry.

can u please say me which notebook intel processors support vp9 decoding, In d links u have given.....there's no information regarding vp9 support

& can u please share whats partial vp9 decoding as i see intel 4th gen & 5th gen support partial decoding of vp9

Hi sreekantt ,

For best support for vp9 get a notebook, with a CPU from 7-th generation, that has minimum Intel HD 630 igpu .

Hello sreekantt,

Any laptop with a 6th Generation Intel® Core™ processor or 7th Generation Intel® Core™ processor will come with VP9 support via hardware. There is a chip in the Intel® graphics controller which will be in charge of decoding VP9 content. Partial VP9 decoding means there is no chip in the Intel® graphics controller that will be in charge of decoding VP9 content. Since there is no chip for decoding VP9 on older graphics controllers (4th Generation Intel® Core™ processors and 5th Generation Intel® Core™ processors) then this is something that will be done by the processor itself instead of the graphics controller. Let me know if you have or not any other inquiry. Regards,Fred

Hi Fred ,

From what I saw on i7-6700k, VP9 10 bit decoding is not fully supported also. Part of the job is done by the CPU going up to 30-40% load sometimes.

Also the power of that hardware decoder depends of igpu frequency and compute power, I saw on this forum problems with 4k decoding on Intel HD 520, so I still recommend a miniimum of Intel HD 630 igpu.

Hello Ronin,

Yes, on 6th Generation Intel® Core™ processors part of the VP9 decoding is going to be done via hardware and part is going to be done by the CPU itself, but the CPU usage during VP9 decoding will be lower than the CPU usage on older generations of Intel processors. Fully VP9 decoding via hardware is can be achieved on 7th Generation Intel® Core™ processor only. Regards,Fred
