Hello! I want to use GPU acceleration for MCU. I bulit libva, media-driver, libva-utils, gmmlib, intel-vaapi-driver and then I exec vainfo, report : error: can't connect to X server! libva info: VA-API version 1.16.0 libva info: User environment variable requested driver 'iHD' libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_11 DRM_IOCTL_I915_GEM_APERTURE failed: Invalid argument Assuming 131072kB available aperture size. May lead to reduced performance or incorrect rendering. get chip id failed: -1 [22] param: 4, val: 0 libva error: /usr/lib64/dri/iHD_drv_video.so init failed libva info: va_openDriver() returns 18 vaInitialize failed with error code 18 (invalid parameter),exit my hardware environment: VGA:description: VGA compatible controller product: G200eR2 [102B:534] configuration: driver=mgag200 latency=64 maxlatency=32 mingnt=16 CPU:Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz /dev/dri card0 system:centos7 Can anyone suggest me how to do this?

A new problem has arisen，After I updated the GPU and CPU, vainfo was normal, but it printed wt Streamencoder - (0x3b22810) MFX init failed, RET -3 during hard coding
