运行`vainfo`时，我收到“无法加载cuvidGetDecodeStatus”的消息。我该怎么办？

我正在关注本指南关于如何在 Firefox 上启用硬件视频加速。我使用 NVIDIA 作为我的显卡。我觉得我已经完成了所有步骤。在最后一部分，您应该使用vainfo终端验证一切是否正常工作。预期输出如下：

libva info: VA-API version 1.13.0
libva info: User environment variable requested driver 'nvidia'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so

      VAProfileVP8Version0_3          : VAEntrypointVLD
      VAProfileVP9Profile0            : VAEntrypointVLD

但我的输出是：

libva info: VA-API version 1.14.0
libva info: User environment variable requested driver 'nvidia'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so

编辑：当我lspci -k | grep -EA3 'VGA|3D|Display'在终端中运行时，我得到的结果如下：

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
    Subsystem: Acer Incorporated [ALI] Core Processor Integrated Graphics Controller
    Kernel driver in use: i915
    Kernel modules: i915

下一步我应该做什么？
