"""
|
|
remove exif tags from uploaded images
|
|
|
|
dependencies:
|
|
exiftool
|
|
|
|
about:
|
|
creates a "noexif" subfolder and puts exif-stripped copies of each image there,
|
|
the reason for the subfolder is to avoid issues with the up2k.db / deduplication:
|
|
|
|
if the original image is modified in-place, then copyparty will keep the original
|
|
hash in up2k.db for a while (until the next volume rescan), so if the image is
|
|
reuploaded after a rescan then the upload will be renamed and kept as a dupe
|
|
|
|
alternatively you could switch the logic around, making a copy of the original
|
|
image into a subfolder named "exif" and modify the original in-place, but then
|
|
up2k.db will be out of sync until the next rescan, so any additional uploads
|
|
of the same image will get symlinked (deduplicated) to the modified copy
|
|
instead of the original in "exif"
|
|
|
|
or maybe delete the original image after processing, that would kinda work too
|
|
|
|
example copyparty config to use this:
|
|
-v/mnt/nas/pics:pics:rwmd,ed:c,e2ts,mte=+noexif:c,mtp=noexif=ejpg,ejpeg,ad,bin/mtag/image-noexif.py
|
|
|
|
explained:
|
|
for realpath /mnt/nas/pics (served at /pics) with read-write-modify-delete for ed,
|
|
enable file analysis on upload (e2ts),
|
|
append "noexif" to the list of known tags (mtp),
|
|
and use mtp plugin "bin/mtag/image-noexif.py" to provide that tag,
|
|
do this on all uploads with the file extension "jpg" or "jpeg",
|
|
ad = parse file regardless if FFmpeg thinks it is audio or not
|
|
|
|
PS: this requires e2ts to be functional,
|
|
meaning you need to do at least one of these:
|
|
* apt install ffmpeg
|
|
* pip3 install mutagen
|
|
and your python must have sqlite3 support compiled in
