Unexpected RTSP behavior when putting app in background
I have an application that displays an RTSP stream and it works as expected. However, if I switch to other app or put the application in the background, I get an unexpected behavior. The stream is replaced by the placeholder widget and never gets connected again. At first I thought it might be a problem from the server, but on further inspection the server has remained stable. I get the following on the console:
