ffprobe already performs such things (plus many others).
For example:

I developed it with the explicit intent (and hope) to get it into FFmpeg, so it
strives to be consistent with both behaviour and coding conventions of the ff*
tools.
XML output could be easily added using a filter for those who like it.
Not to say, I volunteer as a maintainer for it if we decide to integrate it into
FFmpeg, this will simplify many things (mainly related to the building) both for
me and for the ffprobe users.
