好的,以下是一个简单的 html5+yuv 播放器的示例代码:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>HTML5 YUV Player</title>
</head>
<body>
<canvas id="canvas" width="640" height="360"></canvas>
<script src="https://cdn.rawgit.com/xdenser/yuv-canvas/5a4f1da6/yuv-canvas.js"></script>
<script>
var canvas = document.getElementById('canvas');
var player = new YUVCanvas.Player(canvas, {width: 640, height: 360});
var xhr = new XMLHttpRequest();
xhr.open('GET', 'video.yuv', true);
xhr.responseType = 'arraybuffer';
xhr.onload = function() {
var frame = new YUVCanvas.Frame({width: 640, height: 360, chromaWidth: 320, chromaHeight: 180, displayWidth: 640, displayHeight: 360});
frame.setData(new Uint8Array(xhr.response));
player.render(frame);
};
xhr.send();
</script>
</body>
</html>
```
这个示例使用了一个名为 yuv-canvas 的 JavaScript 库来解码和渲染 yuv 视频,它提供了一个 YUVCanvas.Player 类来处理视频播放,一个 YUVCanvas.Frame 类来处理视频帧的解码和数据处理。在这个示例中,我们使用 XMLHttpRequest 来加载 video.yuv 文件,然后将其传递给 YUVCanvas.Frame 来解码和处理,最后将帧传递给 YUVCanvas.Player 来渲染。
