I believe this patch allows encoding animated gifs with transparency:

I'm using the latest nightly static build ffmpeg version N-91330-ga990184007 available from https://www.ffmpeg.org/download.html and still getting no transparency in gifs from apng or mov with alpha channel.

Hey,
It's still doesn't work for animated webp :/
ffmpeg -i test.gif animation.webp
For example, I want to convert this gif - https://imgur.com/tCSn2No to webP,
The output for now is - https://media.giphy.com/media/UqevOuKr66xO04zRBa/giphy.gif
how can I achieve that using ffmpeg?
