thumbnailing for network path very slow. Isn't there a way to explicitly use lower resolutions for thumbnailing

@TheAMM Hi and first thank you for this amazing script. I had been using it for a few weeks, and it's really amazing.

However, thumbnailing for network paths is really slow, and uses much bandwidth. I tried both remote_direct_stream=yes and no. Can't we set somewhere in the script, an option to use, say, 240p version of the stream for thumbnail generation?

(something like what happens in mpv when you include option --ytdl-format="worstvideo[height>=240]/worst[height>=240]"
