Gstreamer hangs application for 2 minutes on first usage of nativePlay or nativePause

[Matthew Ruth]

I'll enable the debug logs and see if Android Studio can pick up anything, but since it's hanging the app I'm not sure if it'll able to run the log statements properly. Moreso, I know it's on the call to nativePlay() because when I comment that line out it runs very smoothly, unless it's the case that the nativePlay() call is actually calling nativeInit() first?

There should be no waiting time to begin with :) You'll have to debug
what exactly it's doing in that time, it shouldn't happen.

I would start by enabling debug logs in GStreamer and check where it
waits all the time. And are you sure it's nativePlay() and not
GStreamer.init()?
