flvjs 不能播放纯视频问题，部分流 MediaDataSource.hasAudio = false 仍不能解决

[ludai223]

当流里只有视频流，没有音频流时，即便通过 MediaDataSource.hasAudio = false 仍不能解决， 具体流信息如下：

  Metadata:
    displayWidth    : 1280
    displayHeight   : 960
    fps             : 0
    profile         :

I'm running into the same problems. It appears a lot of assumptions were made about there being audio when this was written. There definitely isn't a quick fix here.

@ludai223 Please paste the error message from console and chrome://media-internals

In my opinion, it is caused by the pixel format yuvj420p which may not be supported(?) by the browser.

我也碰到了同样的问题，不知道现在改问题有解决吗 @ludai223 @xqq console 信息： Uncaught (in promise) DOMException flv.js:11675 [MSEController] > MediaSource onSourceOpen flv.js:11590 [TransmuxingController] > DemuxException: type = FormatError, info = Flv: Invalid AVCDecoderConfigurationRecord e @ flv.js:11590 flv.js:1251 Uncaught (in promise) Error: Uncaught, unspecified "error" event.

我也遇到同样问题，后来发现客户端视频编码打包时 sps pps 中包含了帧界定符（0,0,0,1）。去除后就 OK 了

纯视频的话你可以参考这样设置。亲测有效。

var flvPlayer = flvjs.createPlayer({ type: 'flv', hasAudio: false,//<====加个这个 isLive: true, url: 'http://www.test.com/live/test.flv' });

是因为yuvj420p的原因吗？我也出现了类似问题
