nsrare / nsgif Goto Github PK

Hi guys,

Great library! Thanks for building this.

I would like to add additional compression to the gifs. It's my understanding that this can be done by reducing the number of colors or increasing redundant patterns along scan lines.

Gifscicle is a command line utility that can compress gifs. Cloudinary is a cloud platform that can do it, too. So I know it's possible but it doesn't look to be easy in Objective-C and Core Graphics.

Does anyone have any advice? Any freelance developers looking for a quick gig?

Why ios10 can't loop forever,always loop one time.

Hi, I use this in my app https://github.com/onmyway133/GifCapture, it works well. But I don't know why this c4c79f2 changed delay time from 0.2 to 0.02? which makes the gif runs very quickly.

In my case, I changed delay time to 0.2 and fps to 5, and it looks great. What do you think @jacobrosenthal @sebyddd ?

This small Objective-C library converts videos to animated Gifs. Unfortunately, the library contains a memory leak which fails to release approximately the same amount of memory as the final size of the gif. Eventually this leads to a crash after multiple sequential conversions.

(This is a duplicate of the previous open issue. I have reposted to make a more concise explanation of the problem for the bugbounty)

Any advice on how this could be done? Thanks for your help

Hi All

NSGIF is a great tool to convert videos. But I am having issues converting videos to gifs.
Usually, a gif does not need to be too sensitive on FPS. But when I am creating a gif file with frames more a certain number, eg. 100, the app gets crashed very easily. I found the reason is caused by the CGImageDestinationFinalize. When finalizing the images, I can see that it brings all image frames into memory and crashed the app.

Anyone has ideas to deal with large number of frames in conversion?

I have an AVPlayer with a video and when I run the createGIFfromURL block, it I go home while it's working and reopen the app, the AVPlayer turns black. However, after a while, if I come back to the app , the AVPlayer returns to the screen.

Any ideas as to why this is happening and/or how to fix it?

How can I play the gif in reverse?

I can't search it in CocoaPods.

It costs time when copy images from asset to gif, maybe add a progress block will be better. We could see a progress when converting a long video.

Reason : Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Source type 1 not available'

As its not handled while using image picker in simulator

I'm using GPUImage to process a video and then save it as a Mov file, once the video is processed, it saves correctly to my video library.

UISaveVideoAtPathToSavedPhotosAlbum (pathToMovie, self, @selector(video:didFinishSavingWithError:contextInfo:), NULL);

in the didFinishSavingWithError function take the video URL and try to run it through NSGIF

• (void)video: (NSString *) videoPath didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo;

  NSURL *fileURL = [NSURL fileURLWithPath:videoPath];
  [NSGIF createGIFfromURL:fileURL withFrameCount:30 delayTime:.010 loopCount:0 completion:^(NSURL *GifURL) {
  NSLog(@"Finished generating GIF: %@", GifURL);
  }];

  if (error) {
  NSLog(@"Error Saving Video To Library: %@", error);
  // Do anything needed to handle the error or display it to the user
  } else {
  NSLog(@"Saved Video To Library:");
  }

}

However I constantly get the following error

Error copying image: Error Domain=AVFoundationErrorDomain Code=-11832 "Cannot Open" UserInfo={NSUnderlyingError=0x12750ed50 {Error Domain=NSOSStatusErrorDomain Code=-12431 "(null)"}, NSLocalizedFailureReason=This media cannot be used., NSLocalizedDescription=Cannot Open}
2016-03-24 16:06:37.191 PhotoBooth[1123:444110] Error copying image and no previous frames to duplicate

Any idea what is causing this?

Once GIF is created and stored in iPhone Photos, Its not getting recognised as GIF for other apps.
e.g in Twitter app, Saved GIF in Photos not getting recognised as gif. Other GIF which are not created using NSGIF and stored in Photos are recognised.

it can’t run on XCode for verison 8.3.

I'm seeing about 30mb of memory that is not being released under the category VM: ImageIO_GIF_Data.

Even after deleting the gif the memory remains allocated.

Any advice?

Thank you for your time

Hi ,it really helps me a lot.But when I convert a lot times,it takes some memory.I can't free these memory.Can you help me?
