Support for multiple video tracks in a single file

For example, I have an MKV with both 1080p and 4k video tracks in it, for playing back at 1080p, plex transcodes the 4k file, badly (due to my processor), splitting the file is not an option, it has 2 lossless audio tracks which I cannot afford to duplicate due to space, and also radarr wont handle the files well at all.
