1 month ago Some more info. When I start a stream, moonlight reprobes the decoding pipeline and then there are additional, more explicit messages:

Describe the bug tl;dr: moonlight built from source with libplacebo falls back to "normal" vaapi/kms (?) rendering, HDR grayed out.
According to the wiki it should be possible on my hardware (Intel iGPU) to request an HDR/10-bit stream when launching moonlight from the command line. Since the snap does not seem to be built with libplacebo / Vulkan support (I checked its snapcraft.yaml), I decided to build from source.
make releasedoes pick up the Vulkan support:After compiling I transferred the binary to the target system and installed the necessary dependencies so that moonlight can start.
Unfortunately the HDR toggle is still grayed out and the logs seem to have some relevant errors:
Steps to reproduce
qmake6 moonlight-qt.pro && make releasesudo apt install libqt6quickcontrols2-6 libqt6quickcontrols2impl6 libqt6svg6 libqt6gui6 libqt6qml6 libqt6network6 libqt6core6 qml6-module-qtquick-controls qml6-module-qtquick-layouts qml6-module-qtquick-window qml6-module-qtqml-workerscript qml6-module-qtquick-templates i965-va-driver./moonlightScreenshots HDR grayed out...
Affected games all
Other Moonlight clients other clients, notably Windows, can enable HDR
Moonlight settings (please complete the following information) nothing, fresh install from source
Client PC details (please complete the following information)
Server PC details (please complete the following information)
Moonlight Logs (please attach) starting, then quitting moonlight: moonlightvk.log
Just to be clear: If a 10-bit stream is not yet possible on my client device that's ok too. I'm primarily interested in finding a definitive answer that is not due to packaging details. (Having a 10-bit stream would be a nice bonus of course. The hardware is able to decode 10-bit HEVC 4:2:0 according to Intel and vainfo.)
