我们提到https://github.com/intel/media-driver/tree/intel-media-21.2.3构建英特尔媒体驱动程序并安装在 ubuntu 21.04 上，然后通过 vainfo 进行测试，但是我们收到以下错误消息：
libva info: VA-API version 1.12.0
libva info: User environment variable requested driver 'iHD'
libva info: Trying to open /usr/local/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_12
libva error: /usr/local/lib/dri/iHD_drv_video.so init failed
libva info: va_openDriver() returns 2
vaInitialize failed with error code 2 (resource allocation failed),exit
请建议并指导我们如何解决这个问题，谢谢。
