Crash upon switching Transition type

Crash upon switching Transition type from Stinger to Fade

I was attempting to set up a Matte Wipe stinger transition on a Source switcher, but was having issues configuring it (completely on my end).

I switched it back to Fade via the dropdown menu in the Source Switcher properties (top most one, not the Show or Hide ones). Once I selected Fade, OBS froze and the crash window popped up.

Upon relaunch, Stinger was still selected (changes to Fade had not yet been saved pre-crash). I switched it to Fade with NO issue or crash after the relaunch.

Hi @exeldro,

I am able to reproduce this issue from Stinger to Fade, Swipe to Slide, Swipe to Fade and others.

Is there any possibility to fix this issue? I would like to send this plugin to Debian. I think it is very useful in several situations.

Thanks!

https://github.com/exeldro/obs-source-switcher/commit/cd65fbbcbcee719e2987d7caa446d683fc702b81 fixes it for me. Will publish a release later this week.

Nope. The problem is not solved and is it intermittent. I can reproduce it changing the Transition Type to: Stinger > Swipe > Slide > Luma Wipe > Stinger > Swipe > Slide > Luma Wipe > Stinger (loop....). Thus, after some changes (3 changes or 10 changes or 15 changes or x changes) I got Seg Fault.

I am attaching a video. It sounds like a buffer overflow or similar issue.

Hi @exeldro, any news? I think this plugin is very interesting to make some automatized actions. I would like to send it to Debian.

I have not been been able to find the cause of the issue yet.

Ok, thank you!
