libsvtav1 编码器适应较好

ffmpeg -i input.mp4 -c:v libsvtav1 -b:v 600k output.mp4

B站1080P 下789kbps 的视频码率 196kpbs音频【音频我觉得96kpbs就够了】

动漫 1080P更低

ffmpeg -i gjj.mp4 -c:v libsvtav1 -crf 42 -b:a 96k 42.mp4

DASH切片

ffmpeg -i 42.mp4 -c:v copy  -c:a copy -dash 1 -f dash output.mpd

Dplayer

<div id="dplayer"></div>
<script src="dash.min.js"></script>

DASH必须在Dplayer上面加装
<script src="DPlayer.min.js"></script>

<script>
const dp = new DPlayer({
    container: document.getElementById('dplayer'),
    video: {
        url: 'demo.mpd',
        type: 'dash',
    },
    pluginOptions: {
        dash: {
            // dash config
        },
    },
});
console.log(dp.plugins.dash); // Dash 实例
</script>

video: {
        url: 'dplayer.mp4',
        pic: 'dplayer.png',
        thumbnails: 'thumbnails.jpg',
        type: 'auto',
    }
