"Intel Corporation 3rd Gen Core processor Graphics Controller" 的 VAAPI 兼容性问题
VAAPI Compatibility issue with "Intel Corporation 3rd Gen Core processor Graphics Controller"
我在 运行 vainfo
时遇到错误
libva info: VA-API version 0.99.0 libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD' libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32
libva error: /opt/intel/mediasdk/lib64/iHD_drv_video.so init failed
libva info: va_openDriver() returns 1 vaInitialize failed with error code 1 (operation failed),exit
这是在安装 Intel Media Server Studio 2017 后发生的（see), before that vainfo was working fine, as i installed below packages and drivers, suggested from here。
sudo apt-get install i965-va-driver libva-intel-vaapi-driver vainfo
Machine configuration : ubuntu 14.04 LTS
Processor : Intel i7(i7-3720QM)
Graphics : Intel Corporation 3rd Gen Core processor Graphics Controller
难道只是因为Intel SDK不支持第三代处理器？
问题出在使用的 Media SDK 版本上，Media SDK-2017 仅支持 4th/5th Generation处理器.
对于3rd generation Machine Media SDK-2015-R1为兼容版本，可从here下载。使用正确的版本和相应的硬件将解决这个问题。
