This looks like a problem with youtube-dl. Try updating it to the latest version.

YouTube changes things from time to time, which can break youtube-dl.

Hi

I actually updated with no luck, I am on 2.16 version.

It seems to me that youtube-dl downloads the chunks but somehow those chunks are not put back as the final video and in return Ytsm thinks that the file is done and writes back a file of 0 kb. Because I see those chunks (those with .fXYZ) are still in the folders which normally cleanup by youtube-dl

Btw this seems to happen only with some channels/videos but not all.
