Hello all,
I'm at a church that uses this plugin to attempt to stream to Facebook and YouTube but we've had consistent crashing issues. I cannot guarantee this plugin is the issue, but otherwise the issue is with OBS itself as we have no other plugins installed, and so I'm making the assumption the issue is with this plugin. It could also be a Facebook issue, but again I'm assuming that isn't the case.
We stream to FB from OBS, and use the plugin to go to YT. If we stream to just FB or just YT OBS works fine, but when we attempt to stream to both we run into a crash. It doesn't happen every time, but it is much more likely to crash than not crash.
I've done the following processes which produce the following results, I'm being thorough to hopefully speed up troubleshooting:
Only FB
1. Open FB and get streaming page setup
2. In OBS start streaming to FB
R. Success
Only YT
1. Open YT and get streaming page setup
2. In OBS start streaming to YT (via plugin)
R. Success
FB then YT
1. Open FB and YT and get streaming pages setup
2. Start streaming to FB
- No crash so far
3. Start streaming to YT (via plugin)
- Crash occurs, OBS closes when I close the crash window
R. Crash after starting YT after FB
YT then FB
1. Open FB and YT and get streaming pages setup
2. Start streaming to YT (via plugin)
- No crash
3. Start streaming to FB
- No crash, but the streams stop getting input
R. OBS doesn't crash but the streams stop receiving input which causes them to close. Oddly OBS still acts like both streams are open and keeps sending input to them, but the streams don't receive it.
This crashing issue isn't exclusive to the newest release of this plugin. Recently we updated from V 0.6.0.1 to V 0.7.2.0 and the issue persisted. We also updated from an older version of OBS to V 30.2.3 and the issue still persisted. I made sure to completely delete the old OBS so everything should be as new as possible. (Also a small note, if you could include the version of the plugin somewhere in the OBS dock that would be great as during the update process I couldn't tell if the old or new version of this plugin was being used as the version isn't listed anywhere.)
From all this testing I am assuming the issue is with the plugin, but it could be an OBS or FB issue. Below is what I believe to be the most relevant parts of the log and crash report from one of the crashes.
Crash Log: Here an issue seems to occur with an OBS dll, which means the issue could be unrelated to the plugin and is actually an OBS issue.

Regular OBS Log: I don't know exactly how to read these so if the issue is clearly shown here I don't know what it is. I assume it has to do with whatever the QOBJECT is, but I'm not certain if that is this plugin or obs-plugintemplate.
- Another note on this is the first FB fail was because FB keeps "forgetting" to save that we use a persistent stream key so when I started the stream OBS couldn't find it. This is to say the Streaming Stop is not related to the crashing issue, but I'm including it to be thorough.

As I'm writing this I see a newest version of this plugin is out so the issue could be fixed there, however I haven't seen anyone with this same issue so for now I'll assume this is an unknown issue. Thank you to anyone who can help out.
