** connection to the remote UI
The web UI for syncthing is binded to localhost. To access the UI of a remote host, create a SSH tunnel:
#+begin_src sh
ssh -L 1235:localhost:8384 -N -f 192.168.0.106
#+end_src
* yt-dlp
- use =--merge-output-format=mkv=
- check what's the best audio and video for a video
- prefer =mp4= for the audio over =webm=
** List of supported formats
#+begin_src sh :results verbatim

#+end_example
** Best audio and video
#+begin_src sh
yt-dlp -f 'bv*+ba' https://www.youtube.com/watch?v=igH-NgcuW2M -o '%(id)s.%(ext)s'
#+end_src
** Download a playlist
Save into =channel_id/playlist_id= directory with the video added to an archive text file:
#+begin_src sh
yt-dlp -f 'bv*[height=1080]+ba' --download-archive videos.txt https://www.youtube.com/playlist?list=PLlVlyGVtvuVnUjA4d6gHKCSrLAAm2n1e6 -o '%(channel_id)s/%(playlist_id)s/%(id)s.%(ext)s'
#+end_src
** Download a channel
#+begin_src sh
yt-dlp -f 'bv*[height=720]+ba' --download-archive videos.txt https://www.youtube.com/c/FootheFlowerhorn/videos -o '%(channel)s/%(title)s.%(ext)s'
#+end_src
* exiftool
** Copy media based on the creation date
#+begin_src sh
exiftool -v -o . '-Directory<CreateDate' -d /data/photos/%Y/%Y-%m-%d/ .
#+end_src
** Move media based on the creation date
#+begin_src sh
exiftool -v '-Directory<CreateDate' -d /data/photos/%Y/%Y-%m-%d/ .
#+end_src
Alternatively, in case the creation date is incorrect:
#+begin_src sh
exiftool -v '-Directory<DateTimeOriginal' -d /data/photos/%Y/%Y-%m-%d/
#+end_src
** Move pdf to a directory
To move papers (for example) using the title and date of creation to a specific destination:
#+begin_src sh
exiftool '-filename<${Title;}.%e' '-directory<CreateDate' -d ~/documents/papers/%Y/ .
#+end_src
** Edit metadata from a google takeout
This [[https://github.com/kaytat/exiftool-scripts-for-takeout][repository]] as a few scripts for =exiftools= that are interesting. In case this repository were to disappear in the future, here is the script to update the metadata from the JSON files:
#+begin_src sh :filename use_json.args
# Fill in from Google's JSON
# Look at all media files and ignore JSON
--ext
json
# Recursive
-r
# Show processed filenames
-v0
# Check if the corresponding JSON exists
-if
(-e "${Directory}/${Filename}".".json")
# Attempt to modify media only if the info doesn't already exist
-if
($Filetype eq "MP4" and not $quicktime:TrackCreateDate) or ($Filetype eq "MP4" and $quicktime:TrackCreateDate eq "0000:00:00 00:00:00") or ($Filetype eq "JPEG" and not $exif:DateTimeOriginal) or ($Filetype eq "PNG" and not $PNG:CreationTime)
# Attempt to read in the JSON
-tagsfromfile
%d%F.json
#
# Write out the tags. Use ConvertUnixTime to try and convert the UTC timestamp
# to a reasonable local EXIF string.
#
# EXIF for regular JPG photos
-AllDates<${PhotoTakenTimeTimestamp;$_=ConvertUnixTime($_,1)}
# PNG-specific
-XMP-Exif:DateTimeOriginal<${PhotoTakenTimeTimestamp;$_=ConvertUnixTime($_,1)}
-PNG:CreationTime<${PhotoTakenTimeTimestamp;$_=ConvertUnixTime($_,1)}
# Quicktime / MP4. Assume that timestamp is in UTC.
-QuickTime:TrackCreateDate<${PhotoTakenTimeTimestamp;$_=ConvertUnixTime($_,0)}
-QuickTime:TrackModifyDate<${PhotoTakenTimeTimestamp;$_=ConvertUnixTime($_,0)}
-QuickTime:MediaCreateDate<${PhotoTakenTimeTimestamp;$_=ConvertUnixTime($_,0)}
-QuickTime:MediaModifyDate<${PhotoTakenTimeTimestamp;$_=ConvertUnixTime($_,0)}
# Clobber everything
-overwrite_original
#+end_src
and to run it: =exiftool -@ use_json.args <takeout_dir>=
