對于h265視頻流的播放，這里采用videojs-flvh265椿胯。
話不多說，看如何實(shí)戰(zhàn)（基于vue項(xiàng)目）。
使用
下載videojs-flvh265
鏈接：https://www.npmjs.com/package/videojs-flvh265
npm install --save videojs-flvh265
public引入包
prod.h265.asm.combine.js
prod.h265.wasm.combine.js
videojs-flvh265.js
上面文件在百度網(wǎng)盤中可下載擅耽。鏈接: https://pan.baidu.com/s/12XXO6vafJJFdzLPeB4_WTw?pwd=8hms 提取碼: 8hms
main.js引入videojs css
import 'video.js/dist/video-js.css';
template使用
<video

javascript使用
import videojs from "video.js";
import "./plugin”;【見下面文件】
