Hello,
I had some experience with MediaInfo from work on the StaxRip video encoding GUI and the mpv based desktop media player mpv.net and also the alternative MediaInfo frontend MediaInfo.NET.
I wrote 3 advanced functions to access the MediaInfo library, maybe somebody here finds it useful at some time and also maybe some of my other projects:
Get-MediaInfo
https://github.com/stax76/Get-MediaInfo
https://github.com/stax76/MediaInfo.NET
Open with++
https://github.com/stax76/OpenWithPlusPlus
StaxRip
https://github.com/staxrip/staxrip
mpv and mpv.net
