Question: where did you get the libraries to use for this?

[AndroidDeveloperLB]

Can you please post links?
This way, we could update to latest versions of them...
Also, I wonder why "libgif" is used, as this is for WebP. Does it also support GIF ?

[McoyJiang]

home page of libwebp https://developers.google.com/speed/webp/
yes, it can support GIF as well

[AndroidDeveloperLB]

It is written that the library uses 3 :
libwebp, libgif, framesequence.

So libwebp is from https://developers.google.com/speed/webp/ ?

Where exactly in it? This:

https://www.webmproject.org/code/#libwebp-webp-image-library

?

And what about the rest?

[McoyJiang]

@AndroidDeveloperLB to be frank, you can simply google libgif and libwebp, even framesequence.
you can get all the result list. But from what i have know, they just don't complile libwebp using CMake, instead they use older Android.mk

I don't see libgif. I see this instead:
http://giflib.sourceforge.net/

About framesequence, I don't see it either.

What I've found is something similar to what you did, here:
