Steamlink gives a black screen, no sound on OSMC

[Koril]

Hi there,

I've been able to install steamlink on my raspberry pi 4 with OSMC (VERSION_ID="2021.12-1"). I can start steamlink, connect to my desktop computer, do a network test, etc..

However when I hit "start playing", steam goes on big picture mode on my desktop computer but I get a black screen on my TV after a few lines of text showing very briefly, one of them being "Bad thread local".

Any ideas what's going wrong, or where I could find some logs to investigate further?

Edit: I was able to retrieve the standard output by starting steamplay from command line:

Have you figured anything out? I'm having the same issue with the exception that I have audio. My log looks very similar as well.

[_I_]

its most likely a hdcp problem
the remote display is not hdcp compliant since its not attached to the host

check the player settings, and look for hardware acceleration and disable it
will skip hardware hdcp checks

Same issue here.
Clean install of OSMC on Rpi4

Steamlink launches but gives black screen once connected. Sound from the host passes through fine though.


In streaming settings 3/3

Hardware decoding is greyed out and set to "disabled"

HEVC video is greyed out and set to "not available"

I have the same problem: the Steam Link interface is displayed, but not Big Picture from my PC. The sound works and I can move through the menus with my controller.

When I installed OSMC, the videos didn't work (black screen). The problem was that pixels were displayed outside the screen. To correct the problem, I did a Video calibration... (Settings / System / Display) so that the whole image is visible on the screen (Samsung UE48H6400). Maybe it's the same problem with Steam Link, but I didn't find any options to calibrate the video output.
