A yt-dlp postprocessor plugin that sets the mtime of all files to a given datetime value by key.
Some file types (namely *.dump files) that can be optionally output by yt-dlp when downloading are not supported.
NOTE: This postprocessor should not be run before files are downloaded. The default when value of post_process is recommended.
Requires yt-dlp 2023.01.02 or above.
You can install this package with pip:
python3 -m pip install -U https://github.com/bradenhilton/yt-dlp-FixupMtime/archive/master.zipSee installing yt-dlp plugins for the other methods this plugin package can be installed.
--use-postprocessor FixupMtime[:[mtime_key=<key>];[mtime_format=<format>]]
Where <key> is the key of your desired datetime within the infojson dictionary and <format> is the format of the datetime.
The default value for the mtime_key parameter is mtime, which will set the mtime of all files (thumbnails, subtitles etc.) to the existing mtime of the video. If mtime_key's value is mtime and the --mtime option was passed to yt-dlp at the time of download, the value will be the datetime of the last-modified header.
The default value for the mtime_format parameter is %Y%m%d. The postprocessor will also attempt to guess the format with yt-dlp's internal list of formats.
Both parameters are optional and can be specified in any order.
Set the mtime of all files to the existing mtime of the video:
--use-postprocessor FixupMtime
Set the mtime of all files to the upload date of the video:
--use-postprocessor FixupMtime:mtime_key=upload_date
Set the mtime of all files using a custom datetime and format:
--use-postprocessor FixupMtime:mtime_key=meta_date;mtime_format=%Y-%m-%dT%H.%M.%S
You can combine multiple invocations, ordered from least to most preferred:
--use-postprocessor FixupMtime:mtime_key=upload_date
--use-postprocessor FixupMtime:mtime_key=release_date
--use-postprocessor FixupMtime:mtime_key=timestamp
--use-postprocessor FixupMtime:mtime_key=release_timestamp
