[ytdl] Problem with yt-dlp plugin

[masha9000]

I'm using yt-dlp for the ytdl module. And it seems that inside gallery-dl it is not friendly with plugins, at least with one - "FixupMtimePP".

The yt-dlp script itself, separately from gallery-dl, works with this plugin without errors.
Usually, I redirect ytdl extractor to the "config-file" path, but the same error occurs with
"cmdline-args": "--use-postprocessor "FixupMtime:mtime_key=upload_date"

ytdl:
Traceback (most recent call last):
  File "gallery_dl\job.py", line 127, in run
  File "gallery_dl\extractor\ytdl.py", line 75, in items
  File "gallery_dl\ytdl.py", line 68, in construct_YoutubeDL
  File "yt_dlp\YoutubeDL.py", line 763, in __init__
  File "yt_dlp\postprocessor\__init__.py", line 42, in get_postprocessor
KeyError: 'FixupMtimePP'

Is this problem unsolvable? Or maybe there is another way to change the modified timestamp to upload_date?

I remove the question completely.
After installing today's build, everything works great!
(The problem was most likely due to my using the nightly build).

You could've also used a metadata and mtime gdl post processor, although they would only be able to set the mtime of main video files. Any info.json etc files generated by yt-dlp would not be touched by them.

            "postprocessors": [
                {
                    "name": "metadata",
                    "mode": "modify",
                    "fields": {
                        "date": "{upload_date:D%Y%m%d}"
                    }
                },
                {
                    "name": "mtime"
                }
            ]

(This is what I've personally used when archiving some YT channels before they get deleted at the end of the year, although I'm currently using a custom script to combine all --embed-... operations into one.)
