OBS launch failed

[XavierColombel]

I'm on a Pi 4 with Bullseye 32bits installed.

I've installed OBS but I failed to launch it. Here is the error I got:

Did you try?

MESA_GL_VERSION_OVERRIDE=3.3 obs

[jmcerrejon]

Tested with the latest command and It works. Now you have it on 64 bits, too 😉

[XavierColombel]

I confirm, on 64 bits, it's on fire ! 🔥 Thanks !

@jmcerrejon did you test on a 32 bits distribution ? It's not working for me, same error about the segmentation fault, even with the MESA_GL_VERSION_OVERRIDE=3.3 obs command.
