# ISSUES:
|
|
# - https://github.com/mpv-player/mpv/issues/5498
|
|
# MPV has an issue when outputting to jpg.
|
|
# Colors look washed out and faded compared to png screenshots.
|
|
# As a workaround this script will output to png then convert to jpg.
|
|
#
|
|
# - https://trac.ffmpeg.org/ticket/2391
|
|
# I want to just use ffmpeg for this script, however it
|
|
# does not support dvd subtitles. For now, I have to
|
|
# rely on mpv to render dvdsubs correctly :(
|
|
|
|
# TODO:
|
|
# - Tidy up this script and add some safety checks
|
|
# - Add some logic to the bot to detect if this script failed
|
|
# - Research more mpv options to avoid having to use mpv + convert
|
|
|
|
# Requiered args supplied by the bot
