我正在尝试使用React Native 视频包将exoplayer用于我的 React Native 应用程序。

我有一个包含 HLS 流和 mp4 视频的应用程序，这些视频存储在我的服务器 (https) 上。

浏览视频时，播放器会卡在无限缓冲区状态并保持这种状态，直到我重新启动应用程序。这是完全随机的。重现问题的唯一方法就是观看视频并多次切换源。

在查看 Android logcat 时，没有错误。adb bugreport 也不起作用。

注意：我对 exoplayer 2.8.0 做了更新，包使用的是 2.4.0。但它不适用于两个版本。

有人熟悉这个问题吗？

提供适当的缓冲区大小并确保您以正确的方式释放 Exo 播放器，还使用播放器错误（ExoPlaybackException错误）方法并将日志放在那里或将数据发送到 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。我也遇到了这种问题，有时无法恢复（2%）。在这种情况下，我已经通知用户出了点问题，请重试。

在这种情况下，建议释放播放器资源并重新准备播放器配置。最后观看的持续时间。Exo 播放器会给你一个错误句柄（事件），应该用来触发播放器释放。

要释放资源，您必须使用以下方法：

ExoPlayer.release

如果您使用postroll广告，您应该更新ExoPlayer到 2.11.0 (2019-12-11)。您可以在该版本的发行说明中阅读：

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

该问题的链接中也有有用的信息。

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.
