Android 铬铸。CastRemoteDisplayLocalService不';不要一次调用创建演示文稿
我使用的应用程序显示实时视频流。我希望该应用程序能够在chromcast上播放视频。我不能使用,因为我必须动态地更改标题(为了安全,我没有找到如何做到这一点)。所以我不得不拒绝这种方法,我决定尝试在GlSurfaceView上播放我的视频。但我面对CastRemoteDisplayLocalService不调用onCreatePresentation,所以我的CastPresentation不创建。 根据日志,PresentationService创建,但不调用CreatePresentation,我不明白为什么。当我停止流媒体时,它还会调用onDismissPresentation 日志: MediaRouterCallback.javaAndroid 铬铸。CastRemoteDisplayLocalService不';不要一次调用创建演示文稿,android,video-streaming,chromecast,Android,Video Streaming,Chromecast,我使用的应用程序显示实时视频流。我希望该应用程序能够在chromcast上播放视频。我不能使用,因为我必须动态地更改标题(为了安全,我没有找到如何做到这一点)。所以我不得不拒绝这种方法,我决定尝试在GlSurfaceView上播放我的视频。但我面对CastRemoteDisplayLocalService不调用onCreatePresentation,所以我的CastPresentation不创建。 根据日志,PresentationService创建,但不调用CreatePresentatio
