Converting large amounts of media files

The idea of the mediaconverter is to take a directory or directory tree of media files and reencoding everything not matching a template.

This can be used for different things:

To create a smaller represention of a audio library which should be transfered to a small player, reducing bitrate and channels, ccause the small audioplayer lacks playback quality and memory.
To reencode a video library, so that specific players, like jellyfin can play them back withou reencoding
To remove unnessary data from media files, like multiple audio/video streams

Missing stuff

currently only reencodes with new bitrate, does not change resolution

Requires Node (18) and ffmpeg installed. After checking out the repo

npm install

analyze videos, grouping them together to show resolutions and bitrates

npm start -- analyze /home/user/Videos

convert vieos that dont match the config/videos.json template

npm start -- copy /home/user/Videos ./convertedVideos

convert some mp3 folder audiobooks to .m4b audiobooks

npm start -- audiobook /home/user/Audiobooks ./convertedBooks
