ExoPlayer无法从文件播放(ExoPlayer not playing from file)

编程入门行业动态更新时间:2024-10-18 08:23:31

我有一个使用HlsRendererBuilder设置的ExoPlayer 。到目前为止，我已经将Uri传递给服务器上的m3u8流文件。它工作得很好。现在我可以选择将视频下载到手机上并从存储中播放。我已成功从给定链接下载文件，将其存储在app私人文件夹中。请求和批准访问外部存储的所有权限。在这种情况下，我从我下载的文件传递一个Uri。 Uri看起来像这样： file:///storage/emulated/0/video/file.mp4 。当我开始播放时，永远不会加载文件。我在日志中没有任何异常或错误。任何人都可以帮我建议一种方法吗？如果需要，我将提供代码片段，但不确定哪个部分有用。

我有ExoPlayer.Listener ，它记录了播放器状态。

当我正在流媒体时，我得到各种状态，从IDLE - > BUFFERING - > READY - > BUFFERING ......等等基于互联网连接或媒体结束ec。当我播放存储文件时，我只获得状态IDLE，没有其他任何事情发生。我永远得到黑屏，直到我finish()活动。

当我尝试从本地存储中播放流文件时，我确实遇到了一个FileNotFound异常，它无法找到该文件，这是流文件中列出的下一部分媒体。我认为问题出在玩家设置中？不确定...

I have a ExoPlayer set up with HlsRendererBuilder. So far I have been passing it an Uri to a m3u8 stream file on the server. It is working great. Now I have an option to download the video to your phone and play it from storage. I have successfully downloaded the file from the given link, stored it in the app private folder. All permissions to access external storage requested and approved. In this case I am passing an Uri from file which I have downloaded. Uri looks like this: file:///storage/emulated/0/video/file.mp4. When I start the playback the file is never loaded. I do not get any exception or error in the log. Can anyone help me to suggest an approach? I will provide snippet of codes if needed, but not sure which part would be useful.

I have ExoPlayer.Listener which logs me of the player state.

When I am streaming I get various states starting from IDLE -> BUFFERING -> READY -> BUFFERING ... so on based on the internet connection or if the media ended ec. When I am playing stored file I only get state IDLE and nothing else happens. I got black screen forever until I finish() the activity.

When I tried to play stream file from local storage I did got an FileNotFound exception that it cannot find the file, next part of media listed in the stream file. I assume the problem would be in the player setup? Not sure...
