do you have mbedtls2 installed?

[31JSON]

No, it is not installed. Does it need to be?

[vaxerski]

for wl_shm, yes

[31JSON]

wl_shm isn't installed either. Or rather, what is it? It's not called as a dependency for any installed package.

[31JSON]

Installing mbedtls2 and restarting did not fix the issue.

Let me know if there is any other information I can provide that would be helpful.

[vaxerski]

well the issue seems to be on your side if anything. Works just fine for me. Does it also happen with xdpw?

[31JSON]

I did a clean install on another computer and it seems to work normally. The install on my streaming computer is an older one from the kernel version 5 days, but is always kept up to date. On the new install, mbedtls2 was pulled in. What I don't understand is that looking at the output of pacman -Sii mbedtls2 shows 必要パッケージ : godot haxe julia neko retroarch. Are any of these related to xdph?

[vaxerski]

nope, shouldnt be. mbedtls2 is an obs dep anyways, not xdph.

Likely its an obs issue here.

I've reported this upstream at https://github.com/obsproject/obs-studio/issues/9733

Fixed upstream in https://github.com/obsproject/obs-studio/pull/9774 (which will be included in OBS 30).
