I thought I saw a post here about a video codec analyzer tool similar to GSpot. I love GSpot and have used it for years, great tool and it is free. But thought I would see if there are other tools that may be as good or better. It doesn't have to be free. I have no particular need, just want to look at similar tools.
Yes, as a quick and accurate report of media file properties, MediaInfo wins. For more detailed information, including GOP structure, I keep GSpot on my machine and use it from time to time. I will note that GSpot does not provide detailed information for all media formats.
