vMix source not loading

[BlackFishMaker]

I just compiled the app in Android Studio and it can see my vMix NDI source but once i open it i just get a grey screen on a Samsung Galaxy S23 Ultra running Android 13. I made sure my vMix is on 1080p25. The NDI Test Pattern application aswell as NDI Screen Capture on the other hand seem to be working fine on 1080p25. Also whenever you close the monitor and select a different source it seems to crash the app for me.

On a side note: I think its great that more people are making NDI tools for Android. The paid one on the PlayStore is garbage. Extremely buggy and 1€ a month? No thank you. However what i can highly recommend are KlakNDI and Nsm. Its a NDI Unity plugin and ive been using it for over a year to get a working NDI monitor on Android. Only downsides are no HX support and no audio support but other than that its been amazing.

Thanks for submitting this issue. The issue that the app is crashing when you switch a source is quite reproducible and I'm investigating this issue. Sadly - my debugger crashes as well - so its not so easy to find out what exactly is the source of this problem.

I can not reproduce the vmix issue. I have testet this app with vmix and it seemed to work fine. Can I ask in which vmix version you experienced this issue?

I was testing it with vMix 23. Could it be possible that its a NDI 4 issue? I can test it with a up to date 26 version in the next few days.

Edit: Can confirm it works with vMix 26 so i guess it was a NDI 4 issue. Is NDI 4 not supported?
