Edit, it works ! :

[Unit]
Description = kodi-standalone using xinit
Requires = dbus.service
After = systemd-user-sessions.service network.target sound.target network-online.target

[Service]
User = kodi
Group = kodi
Type = simple

ExecStart = /usr/bin/kodi-standalone
Restart = on-abort

[Install]
WantedBy = multi-user.target

GBM or is your bug fixed?

GBM or is your bug fixed?

 GBM works well (only washed black.. will investigate) !!!

To test the bug I have to do a little reboot and see if keep a distance of hours without signal lost

For washed out black, you need to force it to full range, which we did with xrandr before, therefore you need the proptest utility, give me the output of this one: https://www.dropbox.com/s/4kk1r9of4okqz8m/proptest?dl=0 (download it, chmod +x it and run it)

Now copy the proptest binary to the directory /usr/local/bin/

Edit your systemd serivce to add before the ExecStar line:

Code:

ExecStartPre=/usr/local/bin/proptest -M i915 -D /dev/dri/card0 101 connector 103 1

sudo systemctl daemon reload
sudo reboot

kodi now needs to be set to "Use Limited Range" and your TV also to limited Range

You should be aware that gbm version with gles is far far behind the quality you get with x11 version.

[Rumpelstiltskin]

IT WORKS !

@dev You're always the best!

IT WORKS !

@dev You're always the best!

 There are some outstanding issues though:
- Image viewer is just black for me (fullscreen)
- HQScalers are implemented very inefficiently (GLES2 only)

It has one advantage over X11:
- When display goes off it switches the rendering to an offline rendering node, when display comes back it switches back to HDMI out (disadvantage: as of now you might loose audio)

[Rumpelstiltskin]

infact, i noticed that:

- Prime render method : Direct To Plane -> have all full audio (AC3-DTS etc)
                                   EGL -> only DTS audio available 

its right?

 There is much more: performance on sw decoder path, HDR, a/v sync, etc

[Rumpelstiltskin]

- HDR ?

 That's not related but also off-topic here. Open an own thread for kodi gbm please.

 Ah yes! Tone-Mapping is too new so I forgot about it. That makes HDR videos really look ugly on GBM.

[FernetMenta]

- HDR ?

 When displaying HDR content on non HDR displays you need tone mapping in order to get correct colours. Implemented for X11 (OpenGL) but not for gbm (gles)
