1. It's not supported 2. Yes 3. I don't think so. The one sample I have didn't work, but feel free to research it yourself.
All of my videos have four files: the video itself (sometimes with multiple audio tracks), the thumbnail or movie poster, the BIF file for "trick play", and an SRT file. Garbage to you maybe, but if you want to use Roku you have to put up with their garbage and there's no shortage of Roku garbage.
Roku has little to no interest in what you're wanting to do. They don't make money from that. Selling a device one time can't compare to the ongoing revenue stream they get from ads and subscriptions, so I don't expect their position to ever change. You might want to look into Plex which can do all kinds of things on the fly, but requires a server powerful enough to accomplish them.
