_ = r"""
first checks the tag "vidchk" which must be "ok" to continue,
then uploads all files to some cloud storage (RCLONE_REMOTE)
and DELETES THE ORIGINAL FILES if rclone returns 0 ("success")

deps:
  rclone

usage:
  -mtp x2=t43200,ay,p2,bin/mtag/rclone-upload.py

explained:
t43200: timeout 12h
    ay: only process files which contain audio (including video with audio)
    p2: set priority 2 (after vidchk's suggested priority of 1),
          so the output of vidchk will be passed in here

complete usage example as vflags along with vidchk:
  -vsrv/vidchk:vidchk:r:rw,ed:c,e2dsa,e2ts,mtp=vidchk=t600,p,bin/mtag/vidchk.py:c,mtp=rupload=t43200,ay,p2,bin/mtag/rclone-upload.py:c,mte=+vidchk,rupload

setup: see https://rclone.org/drive/

if you wanna use this script standalone / separately from copyparty,
either set CONDITIONAL_UPLOAD False or provide the following stdin:
