Q31: HW Transcoding & HDR tone mapping in QTS/QuTS

EDIT: PMS 1.29.2 and above contain native HDR tone mapping support

PMS does not yet include native support for tone mapping in hardware:

For those Intel QTS/QuTS systems with QSV capability (-7xxx or higher, J3455, J4xxx CPU)
Docker Plex provides the workaround.

This FAQ shows how to create a docker container, as a work around, at the command line (a script) which perfectly overlays your existing PMS installation.

  1. Install Container Station and initialize it
  2. SSH into your QNAP as ‘admin’ (an ‘administrative user’ does not have the necessary privileges)
  3. Create a directory anywhere you’d like to hold this script for safe keeping.
  4. Make the script executable
  5. Run the script
  6. Observe as Docker downloads Plex
  7. Open PMS in your web browser
  8. Settings - Server - Transcoder - Show Advanced
  9. Make certain all HW transcoding options are enabled.
  10. SAVE changes

The script:

#!/bin/sh
# author: ChuckPa
#
# Find Container Station 
DOCKER_DIR=$(getcfg -f /etc/config/qpkg.conf container-station Install_path)

# verify installed
if [ "$DOCKER_DIR" = "" ]; then
  echo ERROR:  Container Station not installed.
  exit 1
fi

# Set alias
Docker="$DOCKER_DIR/bin/docker"

# Find Plex
PLEX_DIR=$(getcfg -f /etc/config/qpkg.conf PlexMediaServer Install_path)

# Verify Plex installed
if [ "$PLEX_DIR" = "" ]; then
  echo ERROR: Plex not installed.
  exit 1
fi

#  Stop Plex
/etc/init.d/plex.sh stop

# Warn if no HW detected for HW transcoding
[ ! -e "/dev/dri/renderD128" ] &&  echo "WARNING:  NO transcoding hardware found."

# Remove the old container image (prepare to update the image)
echo Stop and remove Plex container
$Docker stop Plex
$Docker rm Plex

# Remove old image if exists
Image="$($Docker images | grep -i Plex | awk '{print $3}')"

if [ "$Image" != "" ]; then

  echo Removing image
  $Docker stop Plex
  $Docker stop Plex
  $Docker rm Plex
  $Docker rmi -f $Image
fi

# Should be both QTS and QuTS compatible as-is

$Docker run \
-d \
--name Plex \
--network=host \
-e TZ="EST" \
-e LANG="en_US.UTF-8" \
-e PLEX_UID=0 \
-e PLEX_GID=0 \
-e PUID=0 \
-e PGID=0 \
-h DockerPlex \
-v ${PLEX_DIR}/Library/:"/config/Library/Application Support" \
-v ${PLEX_DIR}/tmp:/tmp \
-v ${PLEX_DIR}/tmp:/transcode \
-v /share:/share \
--device=/dev/dri:/dev/dri \
plexinc/pms-docker:plexpass

$Docker start Plex
$Docker update --restart=unless-stopped Plex

Running it:

You may now use container station instead of the native PMS package.

If you wish to update PMS, simply run the script again. Your metadata is not damaged.

DO NOT REMOVE the native Plex package. It will remove your metadata.

DO NOT attempt to use App Center. It is currently bypassed.
Use Container Station to control PMS.
