Subject: [PATCH] GPUImageMovie endprocessing crash issue.
 AVPlayerItemVideoOutput property inside GPUImageMovie sets
 videoProcessingQueue as a delegate, so when GPUImageMovie is deallocating,
 AVPlayerItemVideoOutput won't release then the crash occurs. To fix it,
 AVPlayerItemVideoOutput needs to be released when the process ends. Hence the
 following codes are provided at the end of endProcessing method.
