OBS 27-rc3 and wayland

[nicocarbone]

I am trying OBS 27-rc3 using the edge channel of the snap, under Ubuntu 21.04 running wayland. I don't seem to be able to record the screen or a window. Am I missing a plug-in? Or do I need to connect an interface to the snap?

Are you logged into a Wayland session? It doesn't appear so.

[nicocarbone]

Yes, I am.

[flexiondotorg]

Thanks. This will require more investigation on my part for a seamless solution. But can you try this:

env OBS_USE_EGL=1 snap run obs-studio

That should start OBS Studio using EGL rather than GLX, and you should be able to use "Screen Capture (Pipewire)" and "Window Capture (Pipewire)". Please let me know how you get on :slightly_smiling_face:

[flexiondotorg]

Revision 1243 of the snap (currently in the edge channel only) should detect the display server and enable EGL if Wayland is in use.

snap refresh obs-studio --edge

[nicocarbone]

I tested revision 1244 of the snap and now Pipewire capture options are there. Thanks! However OBS segfaults after choosing the window or the screen to capture :/ I guess this is a different issue? Is there any additional permission I have to give to the snap for pipewire capture?

Thanks!

EDIT: These upstream bugs are not related. More investigation required...

There are a couple of upstream bugs that look related. I'll track them:

• https://github.com/obsproject/obs-studio/issues/4736
• https://github.com/obsproject/obs-studio/issues/4605

[flexiondotorg]

Pipewire is not fully support by snapd it seems. But I've added what I think will be required to have it work when support lands.

[flexiondotorg]

This is now fixed in revision 1249 or newer, currently in the edge channel only.

snap refresh obs-sudio --edge

Thank you! Unfortunately, with revision 1249 I get a segfault on start:

[nicocarbone]

Ok, I think I have a clue of what's happening. After removing and purging the snap and reinstalling, it worked. But just once. After I close and reopen obs, it crashes again. It seems to be trying to restore the previous session and then is when it segfaults.

[Damarus999]

I'm having the same error and crash with the snap on Ubuntu 21.04 in a Wayland session. For what it's worth, the Flatpak of OBS 27 works fine.

[ilarrain]

I'm experiencing the same issue on Ubuntu 21.04 (Wayland), and using current stable and edge snaps. If I delete the scene files, it works ok (1 time, until restarted). rm ~/snap/obs-studio/current/.config/obs-studio/basic/scenes/Untitled.json* This happens even If the scene is blank.
