GPUImageMovieWriter - crash using the method "Unable to call the method with status 2"

Trying to get started with a really wonderful GPUImage base, so kindly provided by Brad Larson, but having a problem.

When you run the SimpleVideoFileFilter sample, it always crashes when completed with the following error:

[AVAssetWriterInput markAsFinished] Cannot call method when status is 2

Does anyone know how to fix this?

Also, you don’t see the video at startup in the simulator, does it work for the simulator?

Launch iOS 6.1 and Xcode 4.6

Thank!

I notice that finishRecordingWithCompletionHandler is called twice, it crashes during the second call
