I wanted to know if there is a recipe/app to utlilze the Full Hardware
acceleration with 8-bit HEVC on Skylake using Ubuntu?
Are you asking for encoder or decoder. Both are supported by Skylake
hardware. You can use vainfo to confirm.
I know there is a recipe for CentOS, what I am really interested in is if
there is one for Ubuntu, since we @Dolby have all our decoders & encoders
running on Ubuntu.
I think here you're talking about something else. Intel-vaapi-driver
works on all linux distributions.
I will be able to build a custom kernel with the latest bits from 01.org
make sure va-api is the latest.
Normally, all kernels that come stock with the distributions work fine
with our driver's last version 1.8.x
Q] Is there a branch of the Linux kernel which is self-sufficient at this
stage to utilize the Full 8-bit HW acceleration on Skylake? Is the
MediaSDK/MediaStudio still necessary, in terms of installing shared
libraries / plugins etc.?
As said you'd need a stock kernel.
Q] Is there a way through the linux kernel that I can permanently
the decode to be done using Full HW acceleration, assuming all input being
8-bit HEVC? This would enable me to use our own decoder and get some numbers
on its performance using full HW acceleration.Would also like to measure how
it does with Hybrid mode for 10-bit HEVC input. May be there is no need for
it, may be the Linux kernel uses HW acceleration by default if the platform
This questions is not applicable to the intel-vaapi-driver.
Q] Was wondering if there is a sample_decode / sample_encode app for
Something similar to the one released with the MediaSDK/MSS.
You can use gstreamer with gstreamer-vaapi or you can use libyami.
You probably need to ask the MediaSDK/MSS people.
We are using the Skylake NUC i7 for now
Q] May not be the best place to ask this but wanted to know if the above SKU
requires me to use the HW plugin while using the sample_decode from the
Media SDK on CentOS -hw -p 33a61c0b4c27454ca8d85dde757c6f8e
I use the same h/w and it works with the middleware libraries mentioned above.
