"wasm-av1" sample introduction
|
|
==============
|
|
This sample demonstrates how to build [wasm-av1](https://github.com/GoogleChromeLabs/wasm-av1) into WebAssembly with emcc toolchain and run it with iwasm. Please first install [emsdk](https://github.com/emscripten-core/emsdk):
|
|
```bash
|
|
git clone https://github.com/emscripten-core/emsdk.git
|
|
cd emsdk
|
|
./emsdk install latest
|
|
./emsdk activate latest
|
|
```
|
|
And set up ensdk environment:
|
|
```bash
|
|
source emsdk_env.sh
|
|
```
|
|
Then run
|
|
```bash
|
|
./build.sh
|
|
```
|
|
to build wasm-av1 and run it with iwasm, which basically contains the following steps:
|
|
- hack emcc to delete some objects in libc.a
|
|
- patch wasm-av1 and build it with emcc compiler
|
|
- build iwasm with simd and libc-emcc support
|
|
- run testav1.aot with iwasm
