More detailed video decoding/encoding operation logging

This is a wish; other decoding APIs have utilities like vainfo, vdpauinfo, nv-video-info to display all supported video codecs, profiles, levels and capabilities, but vulkaninfo currently only prints whether a decoding extension is supported.

I think that would be a fine addition.
I am not very familiar with the video extensions nor have a clue what would be the kind of information wanted. I suppose running those tools you mentioned would be a good starting point.

Unfortunately, I do not foresee this being a very high priority and thus can't focus on it. I'm very open to PR's or detailed explanations of what info is desired, which would help streamline the process.

Idle thought - in addition to showing the relevant information, there should be a ‘video’ command line option that only displays the video information, to streamline usage for those needing that info.
