在Android TV上检测HDMI服务是否已启动

Question

我们遇到HDMI服务问题.我们的Android TV应用程序在STB上设置为默认值.启动STB时,它不会显示启动器,它会立即显示应用程序,播放HLS视频流.对于播放视频,我们使用Exo Player版本2.6.1和Exo Media包装器版本4.1.0.当STB在睡眠后醒来时,我们会一次调查黑屏 - DPAD打开电源.播放列表我们在这种情况下得到的是工作和切换到另一个的渠道很好.此问题通常在同一用户处生成.

这是我们从屏幕为黑色时获取的日志(URL_TEST是我们的播放列表请求):

当一切正常并且在同一设备上启动后播放视频时我们从日志中获得了什么(URL_TEST是我们的播放列表请求):

我们注意到日志时我们有黑屏,我们在视频请求后有这个Displaymanager(HDMI)消息:

09-06 19:21:43.438 W/Displaymanager(   97): interface 4 not support led

当一切正常时,反之亦然 - 请参阅上面的日志.

我们假设黑屏可能是由HDMI服务引起的,当我们请求视频流时,这些服务并不是UP.

我们尝试通过所有这些方法检测HDMI连接(当HDMI连接/ up然后我们开始视频播放时) - 如何检查Android中的HDMI设备连接状态？,但没有任何帮助.

Android版本17.

什么可能导致这个问题？
