问题描述

在Android中，可以使用Android VideoView的任何方式来支持自适应流.

In Android is there any way way to support Adaptive Streaming while using Android VideoView.

我正在VideoView中播放HLS视频.现在，我想根据带宽更改视频质量.如果带宽低，则VideoView应该播放低比特率的内容，如果带宽高，则VideoView应该播放高比特率的视频.

I am playing HLS video inside VideoView. Now i want to change the quality of the video based on the bandwidth. if bandwidth is low then VideoView should play the low bitrate content and if bandwidth is high then VideoView should play the high bitrate video.

我搜索了很多，但没有得到满意的结果.

推荐答案

出于各种原因，应将Android VideoView替换为ExoPlayer，这主要是因为第三方制造商通常会修改VideoView导致对诸如以下内容的不一致支持HLS；因此，我将使用ExoPlayer根据您的回答.

The Android VideoView should be replaced by ExoPlayer for various reasons, mainly because third party manufacturers typically modify the VideoView causing inconsistent support for things like HLS; for this reason I will base my answer on you using the ExoPlayer.

HLS和其他自适应播放协议(例如DASH或Smooth Stream)会根据网络自动更改播放质量.特别地，HlsRenderBuilder使用BandwidthMeter(请参见

HLS, and other adaptive playback protocols such as DASH or Smooth Stream, automatically changes the playback quality based on the network. In particular, the HlsRenderBuilder takes a BandwidthMeter (see HlsRenderBuilder#L131). If you are worried the default functionality isn't efficient enough then you can provide a customized BandwithMeter.

为简单起见，您应该在ExoPlayer周围使用包装器，例如 ExoMedia ，该包装器可与与Android VideoView

For simplicity you should use a wrapper around the ExoPlayer such as ExoMedia that provides quick integration with APIs similar to the Android VideoView
