Overview

In this pull request, I ported a limited bmf to web assembly, and successfully started it in the Chrome browser.

I finished this work

Dependency handling: The BMF project relies on several external libraries, such as FFmpeg, x264, and x265. To resolve linking issues in the WASM environment, I adjusted the compilation options for these libraries, which are currently maintained in my personal repository.

Support modules: To support the features of the BMF module, I compiled libbuiltin_modules as a shared object (.so) and loaded it dynamically at runtime.

Building script: I provide some scripts to help users and developers to easily use and develop in wasm.

Next steps

  • Support multithreaded feature.
  • Try to run an AI application, for example,stable diffusion.

* Use conditional compile in cpp and cmake to allow other cross-compiling
* Some tests and executables are disabled, and no demo are added in this commit.
* Rename `s_bmf_last_error` in `bmf_capi_cpp` due to duplicate symbols.
* Provide with a `build_wasm.sh` script to build the whole bmf with emscripten. However, user still need to build ffmpeg in wasm manually.
