hardware acceleration doesn't work on TVS-473e

[Lohann]

I have an QNAP TVS-473e which does support hardware transcoding, but I'm unable to use it with jellyfin, I followed the Enable Video Acceleration in Jellyfin instructions but without success, then I ssh connected to my qnap to debug it:

#!/bin/sh
QPKG_ROOT=$(/sbin/getcfg jellyfin Install_Path -f /etc/config/qpkg.conf)

vainfo_check() {
  if [ "$1" != "" ]; then
    export LIBVA_DRIVER_NAME="$1"
    export LIBVA_DRIVER_NAME_JELLYFIN="$1"
  else
    unset LIBVA_DRIVER_NAME
    unset LIBVA_DRIVER_NAME_JELLYFIN
  fi

  # Check device
  result=$(
    "${QPKG_ROOT}/jellyfin/bin/ld-linux-x86-64.so.2" \
      --library-path "$QPKG_ROOT/jellyfin-ffmpeg/lib:${QPKG_ROOT}/jellyfin/bin" \
      "${QPKG_ROOT}/jellyfin-ffmpeg/vainfo2" \
      --all 2>&1
    )
    device_name="${LIBVA_DRIVER_NAME:-defaultValue}"
    printf "drive: %s\n%s\n\n" "${device_name}" "${result}"
}

Hardware transcoding works in other apps

If you have the Cayin Media Player installed, I checked that it is able to successfully use the ffmpeg for transcoding with VAAPI, but requires some dark magic:

#!/bin/sh
QPKG_ROOT=$(/sbin/getcfg MediaSignPlayer Install_Path -f /etc/config/qpkg.conf)
FFMPEG_CMD='ffmpeg -y -nostdin -vaapi_device "" -f lavfi -i testsrc=duration=0.01:size=1280x720:rate=30 -map 0:v:0? -vf format=nv12,hwupload -bf 0 -c:v h264_vaapi -low_power false -profile:v main -f null'

env -i /usr/sbin/chroot "$QPKG_ROOT/CodexPackExt" \
  "sh" "-c" \
  "LD_LIBRARY_PATH='/usr/lib/x86_64-linux-gnu:/opt/cdx/lib:/overlay_fs/merge/usr/lib:/overlay_fs/merge/cuda/lib64:' \
  PATH=/opt/cdx/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin \
  FONTCONFIG_PATH=/etc/fonts: \
  LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri: \
  LIBVA_DRIVER_NAME=radeonsi \
  $FFMPEG_CMD"
