Enable nvdec support for plex dockers on unraid
# This should always return the name of the docker container running plex - assuming a single plex docker on the system.
con="$(docker ps --format "{{.Names}}" | grep -i plex)"
echo -n "<b>Applying hardware decode patch... </b>"
# Check to see if Plex Transcoder2 Exists first.
exists=$(docker exec -i "$con" stat "/usr/lib/plexmediaserver/Plex Transcoder2" >/dev/null 2>&1; echo $?)
if [ "$exists" -eq 1 ]; then
# If it doesn't, we run the clause below
# Move the Plex Transcoder to a different location so we can replace it with our wrapper
docker exec -i "$con" mv "/usr/lib/plexmediaserver/Plex Transcoder" "/usr/lib/plexmediaserver/Plex Transcoder2"
# For Legibility and future updates - if needed, use a heredoc to create the wrapper:
docker exec -i "$con" /bin/sh -c 'sed "s/\(^\t\t\)//g" > "/usr/lib/plexmediaserver/Plex Transcoder";' <<'@EOF'
marap=$(cut -c 10-14 <<<"$@")

exec /usr/lib/plexmediaserver/Plex\ Transcoder2 "$@"
exec /usr/lib/plexmediaserver/Plex\ Transcoder2 -hwaccel nvdec "$@"
# chmod the new wrapper to be executable:
docker exec -i "$con" chmod +x "/usr/lib/plexmediaserver/Plex Transcoder"
echo '<font color="green"><b>Done!</b></font>' # Green means go!
# If we ended up here, the patch didn't even try to run, presumably because the patch was already applied.
echo '<font color="red"><b>Patch already applied!</b></font>' # Red means stop!
