Async generating playlists from whole user content channels

When you "mpv https://www.youtube.com/c/SiIvaGunner" mpv will load every single video or song this whole channel has ever made before loading a single video, witch takes 5 mins for me. this should be Async meaning ones it loads 1 video into the playlist it should just play that video and let you watch/hear it while it still loads the other videos into the playlist for as long as it needs to in the background.

and all so for maybe low end hardware, or low end internet. there should be a setting to make it only load 1 video into the playlist at a time then ones that video ends it loads the next one more efficiently with out caring about the next 5 or 500 videos this channel has ever made.

Why I want this is cause this music artist uploads every min every day all most and I would like to just plop there whole channel into mpv and play all there newest current songs they made, its very nice.

Start by tracing how mpv handles a YouTube channel URL such as https://www.youtube.com/c/SiIvaGunner and builds its playlist. Define how playback can begin after the first item while remaining items load, and how an optional one-at-a-time mode should behave; completion should be demonstrated with a large channel playlist and low-bandwidth or low-end-hardware conditions.
