While running `vainfo`, I am getting "Cannot load cuvidGetDecodeStatus". What should I do? [Hardware Video Acceleration Firefox]

I am following this guide on how to enable hardware video acceleration on Firefox. I am using NVIDIA as my graphics card. I feel like I have done all the steps already. At the last part, you are supposed to verify that everything is working using vainfo in the terminal. The expected output is something like:

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
libva info: Found init function __vaDriverInit_1_0
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.13 (libva 2.6.0)
vainfo: Driver version: VA-API NVDEC driver
vainfo: Supported profile and entrypoints

      VAProfileVC1Main                : VAEntrypointVLD

      VAProfileVP8Version0_3          : VAEntrypointVLD
      VAProfileVP9Profile0            : VAEntrypointVLD

But my output is:

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

EDIT: When I run lspci -k | grep -EA3 'VGA|3D|Display' in the terminal this is what I get:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
    Subsystem: Acer Incorporated [ALI] Core Processor Integrated Graphics Controller

What should I do next?
