The program added here can be used to look at all values for all parameters of all streams of a media file. I think it will be useful for identifying interesting parameters. For example: I found it almost impossible to discover in which parameter the camera model of a picture was stored without a tool like this; the official mediainfo program seems unsuited for the task, since it changes the name of some parameters for printing and does not even include all parameters.

Parsing the output of mi.Option("Info_Parameters") seems cumbersome, but I couldn't find another way to get all parameters. Not even the documentation at https://mediaarea.net/en/MediaInfo/Support/Fields lists all available parameters.

Here is the program in action with the Big Buck Bunny short film:
