I am getting this error when I press the filmstrip (record) button on my iPhone. Does anyone know how to fix it? I can take pictures (Pressing camera button), but unable to record footage during playback or live.
For some reason, the application is not compatible with H265 right now at this moment. I spoke to the developer, he will address this issue at some point he said.
The easy solution would be to switch your streams to H264 or H264H.
