GPUImage crashes when going to background

[BigSauce]

When playing or capturing a video using GPUImage, the app crashes when the app goes into background (detected via UIApplicationDidEnterBackgroundNotification) because GPUImage still attempts to perform its work while the app is in background.

It appears that this crash occurs if the app enters background while blurring a view using GPUImage (before the blur is actually applied).

You could try adding:

runSynchronouslyOnVideoProcessingQueue(^{
});

to your applicationWillResignActive

Thanks will try that.
