谷歌的Chromecast：

Question

我使用的默認媒體播放器應用程序投下含有播放列表.m3u8和.TS利用PC啓用chromebrowser Cast擴充文件HLS流鑄HLS時MediaLoad出錯的數據流。第一.TS塊是由接收器的Chromecast應用（默認reciver應用程序）取之後的第二塊傳輸將被取消，錯誤：

media_player.js:24 Uncaught InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable.

任何想法，這個錯誤是什麼手段？視頻和音頻流的流格式是Chromecast媒體播放器支持的H.264視頻和AAC音頻.Content Streamed來自啓用CORS的IIS服務器。

在此先感謝

也有一些是在流中，大約，進一步調試這一點，你需要打開我們的issue tracker票，包括您的流，所以我們可以調試玩家不開心。
