Hi,

I have an issue with GPUImage framework on movie processing.
I am using the exact method referenced by the documentation and it works for 99% of the movies my app is processing, but for the one bellow it doesn't work. The issue is that these kind of movies are the main scope of my app and GPUImage is not working for it.

The application stops here:
GPUImageMovie readNextAudioSampleFromOutput: on the bellow line:
CMSampleBufferRef audioSampleBufferRef = [readerAudioTrackOutput copyNextSampleBuffer];

The application doesn't crashes, but from my point of view is like waiting for another thread to signal.

Could you please check. If needed, I can supply more details.

The movie can be found here: https://www.dropbox.com/s/89x4zzzdodeockp/IMG_2885.mov.

Regards,
Andrei
