Request - Attachment files tab

I’d love to see a new tab for managing attachment files such as thumbnails or custom fonts.

I tried to add a custom thumbnail, whith I usually do using this kind of command:

ffmpeg -i video.mp4 -i cover.jpg -map 0 -map 1 -c copy -disposition:v:1 attached_pic video_covered.mp4

I tried to play with the custom ffmpeg options input in the Quality tab but never achieved what I wanted.

Covers for mkv files have been added in 3.0.0.

I have items in the project for being able to add / passthrough fonts for subtitles and trying covers on more formats. https://github.com/cdgriffith/FastFlix/projects/1

Also wrote up a quick guide on being able to see said thumbnails on each major system and linked it on cover page https://codecalamity.com/guides/video-thumbnails/

I use Icaros already, maybe that’s why I see them well 😯
I couldn’t use windows without it, I use many file formats for my work that windows don’t support out of the box.

I tried the “mp4 thumbnail method” (if i can call it this way) on MKVs, and it never worked well. Depending on the order of arguments, there was either no custom thumbnail at all, or a custom thumbnail but then I couldn’t see the video stream when playing (tested on VLC, Pot Player and HPC, both actual video stream & thumbnail streams are there and can be selected but the result is pure black). Weird stuff. So far only the “mkv thumbnail method” gives good results from the first attempt.
