GPUImage video filter set brightness not working

Question

//The whole code is looking fine, but movieWriter - setCompletionBlock lines are not getting compiled. Doesn\'t know what is the problem in it.

I tried to solve out

Answer 1

This worked for me.

[movieWriter setCompletionBlock:^{

    [filter removeTarget:movieWriter];
    [movieWriter finishRecording];
}];

Just replace above with below one.

dispatch_async(dispatch_get_main_queue(), ^{
    [filter removeTarget:movieWriter];
    [movieWriter finishRecording];
    NSLog(@"aa2233453546565");        
});
