Segmentation fault of vainfo on ubuntu 16.04 with MediaServerStudioEssentials2017R3

[Song__Gibeom]

Hello, I'm trying to install a Mediasdk but I'm a beginner of Intel mediasdk so I followed this reference and used MediaServerStudioEssentials2017R3. 

My hardware and OS infomation is like that:

Processor : Intel Atom x5-Z8350 ( Cherrytrail)

OS: Ubuntu 16.04 

my vainfo command result is incorrect like that 

libva info: VA-API version 0.99.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'

Segmentation fault (core dumped)

I don't know how could I solve this problem. 
Please help me.

Hi Geobiem,

Media SDK requires the hardware in our GPU to support its hardware video acceleration functions, AKA, Quick Sync Video. After checking the following spec, I don't think your hardware has this functional hardware.

https://ark.intel.com/content/www/us/en/ark/products/93361/intel-atom-x5-z8350-processor-2m-cache-up-to-1-92-ghz.html

I think this is why you got a failure in the driver layer.

Hi Mark, 

I saw your reference. Maybe, x5-Z8350 is looked to be not appropriate for MediaSDK.

By the way, many video player in ubuntu ( MPV player, VLC player, etc) works using Intel graphics without Mediasdk driver well. Very smoothly. 

I want to make a fast video player like MPV, VLC. 

Could you teach or give me some advice or a reference? how could I make smooth video playback without MediaSDK ( i.e direct-call vaapi, etc) 

Thanks to your comment.

Hi Geobiem,

What is graphics device id?

lspci -nn | grep VGA

Regards,

Dmitry

Hi Geobiem,

Sorry for the confusion, the cause to the failure won't change but after double checking the spec, Cherrytrail does have the hardware codec; the problem is the software, our driver doesn't support this processor and it is very hard for us to change the code.

So VAAPI via i915 doesn't work, one other thing you can try to use i965 via standard VAAPI path although I never try it before.

Please also forward the device ID as Dmitry requested.

Hi Dmitry, 

my graphics device id is like that

root@lattepanda:~/opencv# lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:22b0] (rev 36)

Thank you.

Hi Mark, 

I see. I will try to search on how to use i965.

Thank you. 

Best regards,
