Hello the EXIFTool team!
With my partner we would like to test another external lib than Exiv2* for reading video metadata in our photos/videos analysis software. We've been said that Mediainfo could be interesting. What do you think of it?
As a preliminary check of what kind of metadata are read by Mediainfo versus Exiftool, I've compared the two with a .mp4 video and noticed that some metadata doesn't appears in Exiftool, such as Chroma subsampling, Scan type...
*Do you know if Exiv2 still really provides reliable metadata for videos?

While I can't offer any opinion on MediaInfo (I had never heard of it until about a month and a half ago), I can share Phil's response to your question about the differences.

ExifTool only extracts metadata, it doesn't decode the video stream to get the actual parameters.
I also believe that Phil has said working to add stream decoding will open a whole bunch of new problems, so this ability is unlikely to be added in the foreseeable future.
