CPU很高，开启MSE后发现视频停止不动

[Eric3495]

视频是ws-flv h264+G711_a 配置如下： Jessibuca({ container: $container, videoBuffer: 0.2, // 缓存时长 isResize: false, useWCS: false, useMSE: true, debug: true, showBandwidth: false, supportDblclickFullscreen: true, timeout: 10, heartTimeout: 5, heartTimeoutReplay: true, // 自动重连 heartTimeoutReplayTimes: 10, loadingTimeout: 5, loadingTimeoutReplay: true, loadingTimeoutReplayTimes: 10, operateBtns: { fullscreen: false, screenshot: false, play: false, audio: false, recorder: false }, forceNoOffscreen: true, isNotMute: false, hotKey:true, });

一直刷错误; Jessibuca: [player events] mseSourceBufferBusy undefined

有测试地址吗，我看下

[Eric3495]

我目前是在局域网中，外网我看看有没有办法搭建一个。之前测试经常延时很高，后面看后台发现CPU占用比较高，基本都是软解。

视频分辨率多少？理论上不应该出现mseSourceBufferBusy 这个说明解码跟不上了。

[Eric3495]

1080p 4096bps， 理论上应该丢帧快速调到最新的也没问题才是。 我改为D1分辨率测试发现也是不行 看起来是不支持，这个信息MSE是不正常的吗， 我用谷歌

你试下useWCS 呢 看看解码能力咋样

我改了， 网页CPU 25%左右， 视频正常， GPU 占6%CPU和13%的GPU。

嗯

[bosscheng]

搞分辨率的，条件允许就用webcodecs 吧，
