Can't get multiple images from video using MPMoviePlayerController. OSStatus -12433

Question

I\'m trying to extract multiple images from a selected video file using MPMoviePlayerController. Below is the code I have written.

movie = [[MPMoviePlayerCon         


        

Answer 1

I had to add the times as floats so:

NSNumber *time1 = [NSNumber numberWithFloat:1.f];

Answer 2

I was getting the exact same error OSStatus -12433 and I am using AVAssetImageGenerator

Turns out my issue was caused by the times I was requesting for the thumbnail. The following is an example of the time that works and a time that gave the error.

CMTime timeGivesError = CMTimeMakeWithSeconds(0.0, 0.0);
CMTime timeWorks = CMTimeMakeWithSeconds(0.0, 1.0);
CGImageRef image = [gen copyCGImageAtTime:timeWorks actualTime:&actualTime error:&error];

I would try adjusting your times and see if there is another option which will work.

Answer 3

I do that using the library iFrameExtractor https://github.com/lajos/iFrameExtractor

Hope this help Good luck
