Detect *.rmvb as video

[rsalmei]

Hi,

Please, is there any way to detect videos like application/vnd.rn-realmedia-vbr as "video"?

I know MIME can't help me, but since this crate is related to file types, perhaps there was a way to capture "*.rmvb" files as "video".

Thanks.

Hello @rsalmei, looking at the various sources used for the data, the "type" could likely be provided for Pronom and Wikidata sources. A lot of the types would likely end up as "Unknown" though. I believe the infer crate provides the type already. Could you expand on your use-case a bit more. For instance, are you trying to detect playable video files? If so, I would image the application you are building would need codecs to support specific media types and not every file that is a "video" would work?

Sure, here is my use-case: it is for my crate refine, specifically the duplicates finder command. I've realized it is reporting movies and their subtitles as duplicated, but I can't simply include the file extension as a deciding factor, as a .avi and a .mkv should indeed be reported as duplicates.

So, my idea was to grab the MIME type of files, and then report dups when they have the same prefix (two or more "video" for example), but not a "video" and an "application".
But imagine my surprise when I perceived some videos (and documents and etc...) are all "application"!
That's why I thought file-type would save me... I realized it is not the MIME type I'm interested, but in the file type.
