Automatic decision both the "Download Folder" and "Custom Name Prefix" with "channel" and "uploaded_date"

[coculi]

Hello,

Firstly, thank you for your all effors of this project.

Now, I have a question of my own though.

I would like to set the download path and file name prefix when submit to download video without set the "Download Folder" and "Custom Name Prefix".

In my own customization though, I would like to save the video like base_download_path/%(channel)s/%(upload_date)s_filename if user post request to download a video without set above two paramters empty.
Then, I think is is easier to organize file location and name pattern.

Some more information about the "channel" property.
The "channel" propery may contains multi-byte character as a channel name.
I think it is good to use for folder name if the MeTube support multi-byte character,
if it does not so, it is also better to parse channel name apart from url like "https://www.youtube.com/@mychannel_name"

I hope to see any update in advance.
Thank you!
