Question

我无法使用chromecast播放完整的MPEG DASH。投射从IOS或Android发送者开始，但是在缓冲后无法恢复并且连接结束。

如果我们看一下调试器，则没有错误。我们只能看到buffering = true。几秒钟后，Chromecast无法播放。

调试器：

ll {type: "MEDIA_STATUS", mediaStatus: {…}}
[Violation] 'setTimeout' handler took 376ms
[Violation] 'setTimeout' handler took 914ms
[Violation] 'setTimeout' handler took 60ms

[Violation] 'setTimeout' handler took 82ms
index2.html:35 ll {type: "MEDIA_STATUS", mediaStatus: {…}}

任何具有或不具有DRM的DASH或平滑流视频都会发生这种情况。

有人有类似的行为吗？ chromecast上的Dash播放正常吗？接收者代码正确吗？
