ffmpegserver.js Canvas 帧捕获并处理 项目简介
这是一个简单的 Node 服务器和开发库用于将 Canvas 帧发送到服务器,并使用 ffmpeg 对视频进行压缩。可独立使用或者跟 CCapture.js 一起使用。使用步骤:安装 Node克隆此项目源码或者下载源码压缩包进入 repo 目录并运行 npm install执行 node start.js示例代码:var capturer = new CCapture( {
format: 'ffmpegserver',
framerate: 60,
verbose: true,
name: "foobar", // videos will be named foobar-#.mp4, untitled if not set.
extension: ".mp4", // extension for file. default = ".mp4"
codec: "mpeg4", // this is an valid ffmpeg codec "mpeg4", "libx264", "flv1", etc...
// if not set ffmpeg guesses based on extension.
} );
capturer.start();
function render(){
// rendering stuff ...
capturer.capture( canvas );
}
requestAnimationFrame(render);
capturer.stop();
capturer.save( function( url, size ) { /* ... */ } );
