I like the idea of something like this with video transcoding (this just does audio). I dont need many of the features of Jellyfin, it'd just be nice to have a browser client for my video files though.
I also look for a sophisticated self hosted, open source transcoding solution as a web app, but in the mean time, the complete opposite: no bells and whistles, no config, no control except size: https://github.com/JMS1717/8mb.local
or do you mean a web based file manager / video gallery with transcoding capabilities?
