Description

WRITE DESCRIPTION HERE If I download a playlist, and the title is changes but ID is the same, it will re-download the video. My requrest is that there’s some option like --ignore-title-change so the file newcar-nepf8cMXRUs.mp4, already downloaded, won’t be download as a separate file with newvideo-nepf8cMXRUs.mp4

If a video is removed from the playlist you still keep it on your computer right? Also, is possible to put comments inside playlist.txt?

The status of a vid on the website doesn’t matter as far as the already downloaded ones are concerned. Otherwise would be absolutely pointless to try to archive something.

Yes, that’s how the comments work.

The date options can be useful too (as only the video title has changed, the upload date should be the same).

Videos can be filtered by their upload date using the options --date, --datebefore or --dateafter. They accept dates in two formats:

Absolute dates: Dates in the format YYYYMMDD.
Relative dates: Dates in the format (now|today)[+-][0-9](day|week|month|year)(s)?

Examples:

Download only the videos uploaded in the last 6 months

$ youtube-dl --dateafter now-6months

Download only the videos uploaded on January 1, 1970

$ youtube-dl --date 19700101

$ # Download only the videos uploaded in the 200x decade $ youtube-dl --dateafter 20000101 --datebefore 20091231
