There is an issue with all Aitum apps and OBS 32 where they will crash your streams if you are live for an extended period of time (more than 30minutes)
I usually stream to Twitch, YouTube, YouTube-Vertical, and Kick with no issues. However, in the last 4 months I have been plagued by my streams freezing and losing all control of my OBS. I thought it was from updating to OBS 32 so I reverted to the previous version of 31 where I had no issues. However it seems that my problems lied with Aitum as I kept encountering the broken streams.
I reduced my streams slowly down from 4 to just 2, and finally to just 1, trying to stream just vertically and figured out that this is where the problems lie.
Aium Multi-stream and Aitum vertical, if left on and sending out data to streaming platforms, will kill your stream and soft crash your OBS (image is frozen but audio is working, and OBS does not recognize it as a crash) if you are live long enough.
I uninstalled all Aitum apps and was able to do a 8hr stream just fine. I reinstalled the RTMP Multiple Output plugin (the multi stream plugin that allows you to set all streams to start right away unlike Aitum despite everyone asking for that functionality since they released the plugin) and was successful in streaming to YouTube, Twitch, and Kick for over 6 hours.
The only functionality that I am missing is the ability to have a vertical canvas that I can stream, but since there is no alternative to Aitum Vertical I will just have to cease doing Vertical streams until they fix whatever this issue is that is causing these crashes.
Hopefully they find a solution to fix these issues, as they are really the only way for those of us looking to take advantage of vertical streaming.
