Description

I would like to see youtube-dl support adding things to the filename such as uploader or channel name and/or name of tagged pornstars via the output template for videos downloaded from pornhub. This is good for better file sorting and grouping files from a channel together, or when searching for downloaded videos with specific people in them

thank you! :)
