Existing video filtering problem
Tue, 05/08/2012 - 07:29
I'm trying to filter and re-encode an existing movie, I'm trying the code example from the github page, but at runtime when finishRecording method is called I get an error:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '*** -[AVAssetWriter finishWriting] Cannot call method when status is 0'
*** Call stack at first throw:

)
terminate called after throwing an instance of 'NSException'
What can be the problem?

With the SimpleVideoFileFilter everything is ok. I get the error on 4.3.5 ipad 2 and 5.0 iphone 4.

OK, then something about how you are setting up your video is causing a problem. What is the code you use to set up your movie source, filters, and movie recorder?
Perhaps by looking at how it differs from the SimpleVideoFileFilter example, you might be able to see something different that could be causing a problem.

ok, thanks, the problem was in blocks, setCompletionBlock solved the problem.
It looks like something is interrupting your video. Do you see this same problem with the SimpleVideoFileFilter example? What iOS version and device is this on?
