Persona 4 Arena Ultimax Proton Video Fix

convert_x264.sh

#!/bin/bash

# Script to transcode P4AU Microsoft ASF media to X264/Opus so that Proton Experimental
# or Proton GE can play cutscene video and audio. If there is no audio, go to
# "Options" > "System Options" and disable "Mute when not in focus" from within the game.
#
# Move the script to ${steam_library}/steamapps/common/P4U2 and run. This script requires
# ffmpeg. If ffmpeg crashes with a segfault, re-run the script until it succeeds. Files
# which have successfully been transcoded already will be skipped on subsequent runs.
#
# The original Microsoft ASF files will be moved to "./asset/wmv", move them back into
# the "asset" directory to undo changes made by this script, or revalidate game files
# from Steam.
