Finally, a new start. :tada:

I started to work on ffmpeg.wasm around Oct. 2019, it was the time
|
|
WebAssembly is still in very early stage and transpiling FFmpeg to ffmpeg.wasm
|
|
was very challenging. (but possible as there was a pioneer project
|
|
[ffmpeg.js](https://github.com/Kagami/ffmpeg.js/)) Over these years, I
|
|
have been trying to make ffmpeg.wasm to be production-grade, but failed
|
|
as FFmpeg is such a powerful framework and WebAssembly is still evolving.
|
|
It wasn't easy to support even one requirements (ex. RTSP) from the community
|
|
and I found it really hard to continue sometimes. In the end, I decided to
|
|
pause a little while and rethink what should be done in the next stage.
|
|
|
|
That's why I started to work on ffmpeg.wasm 0.12.0, it is a major version and
|
|
not backward compatible with 0.11.0. Massive issues are fixed in this version,
|
|
including:
|
|
|
|
- Upgrade Emscripten to 3.1.40
|
|
- Upgrade FFmpeg to n5.1.3
|
|
- Docker build with cache (reduce time to build a new version)
|
|
- Support timeout(), terminate() and other fundamental operations
|
|
- Split libraries to multiple small libraries
|
|
- Rewrite the whole library with TypeScript
|
|
- Merge multiple repositories into one monorepo
|
|
- Offical Web Worker support
|
|
- Offical single thread and multi thread version support
|
|
- Enhanced documentation
|
|
- Official domain name
|
|
|
|
Lots of features are still in the backlog and it requires lots effort to
|
|
even just compelete one of them, such as:
|
|
|
|
- Speed up ffmpeg.wasm using WebAssembly intrinsic
|
|
- Support RTSP protocol
|
|
- Support more popular libraries
|
|
|
|
I believe there is still a long way to go for ffmpeg.wasm to really become
|
|
a production-grade library, but it is defintely a gamechanger and a chance
|
|
to see the potential of WebAssembly and web technologies in general. That's
|
|
why I am working on it and welcome to join us.
|
|
|
|
Hope you enjoy this release :smile:
