.idea 2 | node_modules 3 | package-lock.json -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # 1 简介 2 | 借助于WebAssembly(简称Wasm)技术，实现在浏览器端调用ffmpeg接口完成H.265码流到YUV数据的解码。 3 | 总体流程如下： 4 | ![Decode With FFmpeg and WASM](./doc/wasm.jpg "页面通过wasm调用FFmpeg流程图") 5 | 6 | # 2 依赖 7 | ## 2.1 [WebAssembly (Wasm)](https://webassembly.org/) 8 | 按照官网的定义，WebAssembly (wasm) 是一个可移植、体积小、加载快并且兼容 Web 的全新格式。通过wasm，可以在浏览器里执行原生代码(例如C、C++)。 9 | 目前，wasm技术已经得到主流浏览器的广泛支持（数据来源[Can I Use](https://www.caniuse.com/#search=WebAssembly)）。 10 | ![Browser Suport For WASM](./doc/caniuse_wasm.jpg "主流浏览器对wasm的支持") 11 | ## 2.2 FFmpeg 12 | FFmpeg是一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。采用LGPL或GPL许可证。它提供了录制、转换以及流化音视频的完整解决方案。 13 | 我们代码里主要使用FFmpeg来做解码（decode）。为了减小体积，最终编译生成的wasm里包含的是裁剪过的FFmpeg，主要包含以下几个库： 14 | - libavcodec： 编解码（最重要的库） 15 | - libavutil： 工具库（大部分库都需要这个库的支持） 16 | - libswscale： 视频像素数据格式转换 17 | 18 | # 3 具体实现 19 | ## 3.1 接口 20 | 编译生成的wasm文件对外提供四个接口： 21 | - openDecoder：初始化解码器； 22 | - decodeData：解码传入的H.265码流数据； 23 | - flushDecoder：清空缓存数据； 24 | - closeDecoder：关闭解码器； 25 | 26 | ## 3.2 实现细节 27 | 解码过程中使用到的FFmpeg API及解码流程如下图所示： 28 | ![decoder](./doc/decode_video.jpg "调用FFmpeg API解码流程") 29 | 30 | ## 3.3 如何使用 31 | 最终的编译结果是两个文件，一个是包含ffmpeg库的wasm文件，另一个是胶水代码(js文件)。页面里引用js文件时，胶水代码会加载wasm。 32 | Javascript与WASM的数据交互： 33 | ```js 34 | // 发送： 35 | var cacheBuffer = Module._malloc(data.length); 36 | Module.HEAPU8.set(data, cacheBuffer); 37 | var ret = Module._decodeData(cacheBuffer, data.length, pts); 38 | 39 | // 接收： 40 | var videoSize = 0; 41 | var videoCallback = Module.addFunction(function (addr_y, addr_u, addr_v, stride_y, stride_u, stride_v, width, height, pts) { 42 | console.log("[%d]In video callback, size = %d * %d, pts = %d", ++videoSize, width, height, pts) 43 | let out_y = HEAPU8.subarray(addr_y, addr_y + stride_y * height) 44 | let out_u = HEAPU8.subarray(addr_u, addr_u + (stride_u * height) / 2) 45 | let out_v = HEAPU8.subarray(addr_v, addr_v + (stride_v * height) / 2) 46 | let buf_y = new Uint8Array(out_y) 47 | let buf_u = new Uint8Array(out_u) 48 | let buf_v = new Uint8Array(out_v) 49 | let data = new Uint8Array(buf_y.length + buf_u.length + buf_v.length) 50 | data.set(buf_y, 0) 51 | data.set(buf_u, buf_y.length) 52 | data.set(buf_v, buf_y.length + buf_u.length) 53 | var obj = { 54 | data: data, 55 | width, 56 | height 57 | } 58 | displayVideoFrame(obj); 59 | }); 60 | var codecType = 1; // 0 - H.264, 1 - H.265 61 | var ret = Module._openDecoder(codecType, videoCallback, LOG_LEVEL_WASM) 62 | // 需要把回调通过openDecoder方法传入C层，在C层调用。 63 | ``` 64 | 65 | # 4 编译 66 | ## 4.1 安装Wasm工具链Emscripten 67 | 安装步骤可参考其[官方文档](https://emscripten.org/docs/getting_started/downloads.html)，目前支持 Windows, MacOS, Linux。 68 | 69 | 建议版本：1.38.45， 编译运行都没问题。 70 | 71 | ## 4.2 下载FFmpeg 72 | ```bash 73 | mkdir goldvideo 74 | cd goldvideo 75 | git clone https://git.ffmpeg.org/ffmpeg.git 76 | cd ffmpeg 77 | git checkout -b 4.1 origin/release/4.1 78 | ``` 79 | 这里切到了4.1分支。 80 | ## 4.3 下载本文的代码 81 | 保证FFmpeg目录和代码目录平级。 82 | ```bash 83 | git clone http://github.com/goldvideo/decoder_wasm.git 84 | cd decoder_wasm 85 | 86 | 目录结构： 87 | 88 | ├─goldvideo 89 | │ ├─ffmpeg 90 | │ ├─decoder_wasm 91 | ``` 92 | ## 4.4 编译 93 | 进入代码目录，根据需要，以下命令三选一执行： 94 | ```bash 95 | ./build_decoder_264.sh //支持解码 H.264 96 | ./build_decoder_265.sh //支持解码 H.265 97 | ./build_decoder_264_265.sh //支持解码 H.264 和 H.265 98 | ``` 99 | 100 | # 5 测试 101 | ## 5.1 WebGL 102 | H5使用Canvas来绘图，但是默认的2d模式只能绘制RGB格式，使用FFmpeg解码出来的视频数据是YUV格式，想要渲染出来需要进行颜色空间转换，可以使用FFmpeg的libswscale模块进行转换。 103 | 为了提升性能，这里使用了WebGL来硬件加速，主要参考了这个项目，做了一些修改： https://github.com/p4prasoon/YUV-Webgl-Video-Player 104 | 105 | ## 5.2 启动： 106 | 107 | ```bash 108 | npm install 109 | npm start 110 | ``` 111 | ## 5.3 测试页面： 112 | 113 | ``` 114 | http://localhost:3000/test/main.html 115 | ``` 116 | 117 | # 6 参考项目 118 | [WasmVideoPlayer](https://github.com/sonysuqin/WasmVideoPlayer). 119 | 120 |
