WebP animations support for iOS & Android

Hi there,

I’m getting the exception below when I try to Load a Gif with the url: https://media3.giphy.com/media/3ohzdKbEOsJtrg2iCQ/200.webp That is a gif from the Giphy directory. if I use the *.gif extension it does work, but I am trying to use webp cause the 2x smaller. Do I have to do any specific setup?

I tried the sample app, and it also gives me the same exception.

[0:] Image loading failed: https://media3.giphy.com/media/3ohzdKbEOsJtrg2iCQ/200.webp System.BadImageFormatException: Not a valid bitmap at FFImageLoading.PlatformImageLoaderTask1[TImageView].GenerateImageFromDecoderContainerAsync (FFImageLoading.IDecodedImage1[TNativeImageContainer] decoded, FFImageLoading.Work.ImageInformation imageInformation, System.Boolean isPlaceholder) [0x000a8] in C:\projects\ffimageloading\source\FFImageLoading.Droid\Work\PlatformImageLoadingTask.cs:215 at FFImageLoading.Work.ImageLoaderTask3+<GenerateImageAsync>d__104[TDecoderContainer,TImageContainer,TImageView].MoveNext () [0x002c4] in C:\projects\ffimageloading\source\FFImageLoading.Common\Work\ImageLoaderTask.cs:307 --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess (System.Threading.Tasks.Task task) [0x0003e] in <43dbbdc147f2482093d8409abb04c233>:0 at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification (System.Threading.Tasks.Task task) [0x00028] in <43dbbdc147f2482093d8409abb04c233>:0 at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd (System.Threading.Tasks.Task task) [0x00008] in <43dbbdc147f2482093d8409abb04c233>:0 at System.Runtime.CompilerServices.ConfiguredTaskAwaitable1+ConfiguredTaskAwaiter[TResult].GetResult () [0x00000] in <43dbbdc147f2482093d8409abb04c233>:0 at FFImageLoading.Work.ImageLoaderTask`3+<RunAsync>d__109[TDecoderContainer,TImageContainer,TImageView].MoveNext () [0x004ae] in C:\projects\ffimageloading\source\FFImageLoading.Common\Work\ImageLoaderTask.cs:588

Thanks for your replay. You built a quite complex library.

I am using the gif animation on a chat feature on our APP. for now I am using the *.gif and sticking with smaller formats. But that would be big Plus.

Have a nice day!

First we need to add a new type WebPAnimated, here:

https://github.com/luberda-molinet/FFImageLoading/blob/master/source/FFImageLoading.Common/Helpers/FileHeader.cs

Then, on Android it would be easy as adding GifDecoder for WebPAnimated type: https://github.com/luberda-molinet/FFImageLoading/blob/87c69858b4546d8734968ae40fac4e616d256514/source/FFImageLoading.Droid/Work/PlatformImageLoadingTask.cs#L116

On iOS we’ll need to add a new decoder, which merges two decoders:

• https://github.com/luberda-molinet/FFImageLoading/blob/87c69858b4546d8734968ae40fac4e616d256514/source/FFImageLoading.Shared.IosMac/Decoders/WebPDecoder.cs
