Animated GIFs

[skyjake]

The inline image viewer can load GIF images, but animated ones need additional work. Fortunately in v1.2, media handling was generalized a bit so a new type of media player could be added for animated images.

Here's a helpful reference: https://gist.github.com/urraka/685d9a6340b26b830d49

You mean only animated GIFs and not animated PNGs (APNGs) like this one?

For me PNG format is far superior to GIF format and support for animated PNGs would be great.

[skyjake]

Yeah for now only GIFs, since stb_image is doing the heavy lifting here.

APNG is interesting, but I expect it to require writing more code to extract the animation information and additional frames from the PNG chunks.

@skyjake There is a patch for APNG support in stb_image.h, can't you use it?

[skyjake]

I likely could use that, but I'd rather stick to the unmodified stb_image.h from the main nothings repository, as there is no guarantee this patch will be updated whenever the main stb_image.h is updated.

I see this as quite a low priority feature. On the whole, I'd rather invest my time into better external viewer integration (#135).

+1 for simple Animated GIF support, though I get not wanting to add more code in.

Perhaps a nice compromise would be to add text to the mime-type/sizing that says if the GIF is animated, so a reader knows to download it and view it with an external program? Looks like it would fit nicely here:
