HUGE memory spike causes crash even for 1 frame per second on a 60 second long mp4 video

[Pranoy1c]

I have a 3.9 MB 60 second long mp4 video which I am trying to convert to GIF. Testing on iOS 9.3.
Even when I have set the request.framesPerSecond to 1 which should only have 60 total frames in the entire GIF, my app memory spikes to around 270 MB.

Looking further, the memory spike occurs at the if (!CGImageDestinationFinalize(destination)) {
line of the createGIFforTimePoints method. Any clue what can be done to fix this?

NSURL *videoURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"clip" ofType:@"mp4"]];
    NSString *destinationPath = [[self applicationDocumentsDirectory].path
                                 stringByAppendingPathComponent:@"mygif.txt"];

    NSGIFRequest * request = [NSGIFRequest requestWithSourceVideo:videoURL destination:[NSURL fileURLWithPath:destinationPath]];
    request.framesPerSecond=1;
    request.scalePreset=NSGIFScaleOptimize;
    request.progressHandler = ^(double progress, NSUInteger position, NSUInteger length, CMTime time, BOOL *stop, NSDictionary *frameProperties) {
        NSLog(@"%f - %lu - %lu - %lld - %@", progress, (unsigned long)position, (unsigned long)length, time.value, frameProperties);
    };

    [NSGIF create:request completion:^(NSURL *GifURL) {
        //GifURL is to nil if it failed or stopped.
    }];

setting the scalePreset to NSGIFScaleVeryLow and request.framesPerSecond=5 reduces the memory to 100MB which is sort of acceptable. though pretty bad quality. My original video is 640x360 resolution. So the line NSGIFScaleRatio when set to NSGIFScaleOptimize was falling in the NSGIFScaleMedium case of the switch statement which meant it would scale to .5. This is most likely the cause of the issue.

Sorry too late. But I'm working to fix that issue!
I'll notify when release the new version.
