Vaudeville Proton Video Fix

convert_x264.sh

#!/bin/bash

# Script to transcode Vaudeville 4K AVC1 media to 1080p X264/Opus so that Proton
# Experimental or Proton GE can play cutscene video and audio.
#
# Move the script to ${steam_library}/steamapps/common/Vaudeville 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.
#
# Clear steam's shadercache for the game after running this script:
# rm -rf ~/.steam/steam/steamapps/shadercache/2240920/
#
# The original files will be moved to "./Vaudeville_Data/avc1", move them back
# into the "Vaudeville_Data" directory to undo changes made by this script, or
# revalidate game files from Steam.
