Exoplayer 无限缓冲状态

Question

我试图在React Native应用中使用React Native video包使用exoplayer。我的应用程序中有HLS流和mp4视频，这些视频存储在我的服务器（https）上。
浏览视频时，播放器会陷入无限缓冲状态，并保持该状态，直到我重新启动应用程序。这完全是随机的。唯一重现问题的方法就是多次切换源并观看视频。
查看Android logcat时没有错误。adb bugreport也无效。

注意：我将ExoPlayer更新为2.8.0版本，但该软件包仍在使用2.4.0版本。但两个版本都无法正常工作。

有人了解这个问题吗？

这可能与您的服务器的可靠性有关。 - joshkmartinez

Answer 1

在这种情况下，建议释放播放器资源并重新准备具有上次观看持续时间的播放器配置。Exo Player将为您提供错误处理（事件），该事件应用于触发播放器释放。

为了释放资源，您必须使用以下方法：

ExoPlayer.release

- Glenford Fernandes

Answer 2

提供适当的缓冲区大小，并确保以正确的方式释放Exo播放器，还要使用on player error（ExoPlaybackException错误）方法，在那里放置日志或将数据发送到Firebase分析。有时很难找到Exoplayer卡住的真正原因。它也可能是源错误或渲染错误。我也遇到过这种问题，有时无法恢复（2％）。在这些情况下，我已通知用户发生了错误，请再试一次。

- Richa Shah

Answer 3

如果您正在使用后置广告，您应该将 ExoPlayer 更新到 2.11.0（2019-12-11）。正如您可以在该版本的 发布说明 中阅读到的那样：

HLS:
Fix issue where streams could get stuck in an infinite buffering state after a `postroll` ad (#6314).

在链接中也有关于该问题的有用信息。

That's actually another bug in our dev branch that needs fixing unrelated to what's reported here. The bug reported in this issue is HLS-specific and happens because we wait for stream information after the `postroll` which never arrives as the stream already finished loading.
