RPI4 OSMC HW acceleration

kurac338 commented 1 year ago

Hardware decoders are not detected in moonlight-qt on RPi 4 (4 GB) running the latest OSMC Buster & Bullseye builds.

To reproduce setup your RPI client using the following guide.

In summary:

clean install of latest OSMC distro (Bullseye 2022-09-01 or Buster 2022-03-01 images)
setup the config-user.txt with the following properties:
- add gpu_mem=128
- add dtoverlay=rpivid-v4l2
- leave dtoverlay=vc4-kms-v3d (despite the moonlight docs, see note below)

Notes:

adding dtoverlay=vc4-fkms-v3d will prevent OSMC / Kodi 19 from booting, so thats not an option.
adding H264_DECODER_HINT=h264_v4l2m2m DRM_FORCE_DIRECT=1 moonlight-qt didn't seem to do anything 😢

These are screenshots from a Windows client, but I intend to run the exact same configuration on the RPi.

Looks like libgl isn't installed by default on OSMC. Could you try this version and run update moonlight from the add-on settings? Clean install should also work.

@veldenb Your Sir are a legend. The missing libgl1 package was the, the root cause. I can confirm that your addon/plugin and moonlight-qt work great now.

On a side note, I don't know if this is a known issue, but starting the addon is not possible from the Kodi's top level GUI menus (at least on OSMC). I need to do the following: Games -> Game addons -> Moonlight -> Moonlight before I can enter the QT GUI.

That's how stuff works in Kodi. You can use Bookmarks to add Moonlight or a game to Bookmarks -> Moonlight/game
