Description
mathiasbynens.be/demo/animated-webp-supported.webp cannot load animated webp images or save one correctly. Maybe the method I used is wrong.
Really appreciate for your work~
Steps to Reproduce
1.download the example image
2.load with code
using (var imgStream = new MemoryStream())
{
await Request.Body.CopyToAsync(imgStream);
if (imgStream == null || imgStream.Length == 0)
{
return Fail("image can not be null");
}
var buffer = new byte[imgStream.Length];
imgStream.Position = 0;
await imgStream.ReadAsync(buffer, 0, buffer.Length);
//using(Image img=Image.Load(file)) //At first i wrote this line which turned out img.Frames.Count=1
using (Image img = Image.Load(new DecoderOptions { MaxFrames = 100 }, file))//this way turned out img.Frames.Count=12
{
var filePath= AppContext.BaseDirectory + Guid.NewGuid().ToString() + ".webp";
await img.SaveAsync(filePath);
}
}

@marshafan we do not support encoded animated webp yet. That is the last missing feature for webp. See: Missing features webp
