OBS crashes during Scene Collection switch #8

Open Wolfi0ne opened 3 years ago

Wolfi0ne commented 3 years ago

Following Scenario:

Scene Collection A has obs-virtual-cam-filter set up and active, Scene Collection B hasn't any filter set up.

Switching from Scene Collection A to Scene Collection B causes a crash with OBS. If the filter in Scene Collection A is set to inactive, the switching from Scene Collection A to Scene Collection B works flawless.

Wanted status: no crash when switching from Scene Collection A (with active filter) to Scene Collection B (and vice versa).

Used obs-virtual-cam-filter version: 0.0.4

Do you have a crash log file for me or does OBS freeze?

No, with activated obs-virtual-cam-filter OBS just closes itself. Before I started again, I made sure no instance is running (checked via Task Manager). This happened 3 times in a row - I didn't even thought about it, because Scene Collection B has not filter set up - I was riddling what I have set up in Scene Collection B that could cause it, until it came in my mind that it it is something in Scene Collection A that causes it.

Thats why I deactivated the filter in Scene Collection A, and the switch to Scene Collection B (and vice versa) worked. Activated the obs-virtual-cam-filter in Scene Collection A again: switch to Scene Collection B closes OBS again.

OBS Version is 26.1.1 btw,

I can confirm the same issue with OBS 27.0.1 and Virtual Cam Filter 0.0.4: if Virtual Cam Filter is applied onto a scene (even if not activated) and one tries to switch a scene collection, OBS Studio crashes. Unfortunately, also for me without a crash log. But once I removed Virtual Cam Filter again from the scene, OBS Studio switches just fine between the scene collections.

Ok, when one tries to switch scene collections, OBS Studio always crashes if Virtual Cam Filter is applied onto a scene, but most of the time OBS Studio is not writing a crash log. But when it writes it, here is a typical stack trace where one can see Virtual Cam Filter be part of the game:

Same problem in Pop!_OS 21.04 and OBS 27.0.1. It works until you change the scene. For installation process, I just copied the virtual-cam-filter.so to /usr/lib/obs-plugins directory.
