Im investigating if its possible to use renderstreaming to send video output of an app to a browser. It looks like it should all work, but during signalling the connection is disconnecting just before it usually will stream video, Did you try if this direction works in general ? Android Unity App => Browser ?
If yes, would this always have worked or is this a more recent feature ?
Android Unity app → Browser should work. What’s the problem do you have?
Basically not clear why it does not fully go into connected state / or does not start streaming the image.
The application works correctly on x86.
Could the videostreamsender “Screen” vs Camera vs Texture provide further hints what is going wrong?
on Android it seems that logcat does not really show all error messages.
When using the android project in the editor the application works correctly and connects fully and also starts streaming video.
I have also tried to start a conversation with you to provide further detail.
There are frequently problems that mobile device can’t connect the signaling server because of a wrong URL.
You can check the log on the signaling server.
Another possible cause is that two peers are not in the same local network. Please check the network connection of each peers.
In this case signalling does not seem to be the issue , the signalling stops before going from signallingstate “stable” to connected, and the connection is disconnected at the moment when the video track is created and would normally start sending video. May be libwebrtc crashes at this moment. After that i cannot make a connection to the process anymore.
Crash?
Can you share me the crash log?
I was able to reproduce the same behavior on a different (more standard) android phone (Pixel 5)
it does the signaling part and then it seems to never transistion to stable connected state but then disconnects. not quite clear to me why. I believe errors may not be showing up in logcat properly.
