Converts GIFs to sane controllable embed video players Basically does something browsers should do natively.
If your favourite platform doesn't convert user GIFs into videos, this extension will help you.
The animation above uses WebM (more optimised than GIF) which is not currently supported for now
Due to the usage of WASM, is a bit tricky to upload this extension into web extension stores.

Chrome and other Chromium browsers
- Go to
chrome://extensions/ - Enable the
Developer mode(toggle on top right corner) Load unpackedand point to the extension folder

Here is a short GIF you can try to convert once you install the extension. You need to Right Click -> GIFSane and choose your preferred conversion method.
- It uses
ffmpeg.wasm, which is quite slow for long videos - It uses Manifest V2 because some WASM CSP directives are not implemented and
ffmpeg.wasmusesdocumentselectors within its code. To port it to Manifest V3, the code will need to be placed in a worker which doesn't have access to the DOM (document). - It can't be published on Chrome Store due to Manifest V2 :)
- It will stop working in January 2023 in Chrome if this can't be ported to Manifest V3.
- GIFs (sane) playback control using WASM and FFmpeg: how it was implemented, and some caveats and tricks that were required during the implementation
- Add support to sending to a remote server
- Write down landing page
- Try to replace FFMPEG with something else?
- Deal with
.webp(ffmpegwasm doesn't seem to like those)
