Excessive CPU usage gets the app killed by iOS

Open app

Open network stream

Leave playing and return to home screen or lock the screen

Open a different app that plays audio to determine VLC to pause playback

Lock the screen

Unlock

Return to VLC

Tap the play button

Lock the screen

Result: plays for a minute or so then gets killed by iOS with reason:

"Action taken: Process killed CPU: 48 seconds cpu time over 48 seconds (100% cpu average), exceeding limit of 80% cpu over 60 seconds"

I'll attach iOS Analytics crash logs
