Video grabber QoL enhancement.

[rey]

Thanks again for hints!

this behavior seems to depend on whether yt-dlp detects the presence of ffmpeg.

Yet that's what actually strange: same site/same video but yt-dlp in Cent 5.1.1130.129 grabs it proper, while newer in 5.2.1168.83 fails and takes top quality = so it's not about ffmpeg, but either yt-dlp changed smth in it's methods between these two Cent versions, or newer Cent calls yt-dlp differently than before.

BTW, i've heard yt-dlp can actually provide variants of what it can grab - how about adding that to Cent grabber?(quality selection)
It's probably quite a lot of work, but i can't hold to ask.
