Thanks for the speedy reply!! Is it just me or is getting info on writing metadata tags proving to be a challenge? I'm having a hard time finding comprehensive metadata documentation by media and container type (ex: I know mkv allows for custom tags but mp4 doesn't). I checked out that webpage you sent Andrey but wasn't able to find all of the flags and their parameters. I will look at it again. If there is a page listing everything that would be great.
You are correct Kieran... media_type is an integer. Thanks. I should have thought to try that first although I wouldn't have thought to go to "10". Most likely just 0 and 1. Thanks for sending those github pages!! That gave me what I needed for this flag. I came across this page (ttps://thediveo-e.blogspot. ca/2016/06/adventures-in-ffmpeg-meta-data-writing.html) with a limited set of flags which is what I've been going by but it doesn't have media_type. I discovered this flag via a gui program I have that converts mkv to mp4 and it has built in tagging. You can select "Movie", "Music", "TV Show" and a few others. I assumed this was a string field but obviously they have the selections mapped to integers as in "1" = Movie, etc. Given metadata is the cornerstone by which we live our lives I'm surprised I'm having such a hard time finding information. I just assumed there would be a metadata bible out there for media. :-) I'm keeping my own document of all the sites I find info on in hopes of piecing everything together. :-) Cheers.
