MediaPlayer.seekTo（）不无缓冲的位置工作 [英] MediaPlayer.seekTo() does not work for unbuffered position

问题描述

我用的MediaPlayer从网络打单首MP3歌曲。数据源是一个HTTP URL。

I use MediaPlayer for playing a single mp3 song from network. Data source is a HTTP URL.

让我们假设有下面的播放状态。

Let's assume we have following playing state.

宋时间：1:00

进展情况：0:10

当前缓冲进度0:30

Current buffering progress 0:30

比方说，我想跳过一首歌的某一部分，并寻求前进。我做它MediaPlayer.seekTo（）方法。如果我试图缓冲的位置（0:20），它被正确执行。但是，如果我努力还没有被缓冲，但（0:40）的位置上的MediaPlayer的行为古怪。它立即指示它已正确seeked而不等待一个缓冲器来填补。事实上，它继续播放在它是寻求前相同的位置。从现在开始MediaPlayer.getCurrentPosition（）方法返回错误的位置。当播放到达终点，并OnCompletionListener.onCompletion回调被称为当前媒体播放器的位置是不是整首歌曲的持续时间要高得多。

Let's say I want to skip some part of a song and seek forward. I do it with MediaPlayer.seekTo() method. If I seek to buffered position (0:20) it is performed correctly. But if I seek to a position which has not been buffered yet (0:40) the MediaPlayer behaves odd. It indicates immediately that it has seeked correctly without waiting for a buffer to fill. In fact it continues playing at the same position where it was before seeking. From now on MediaPlayer.getCurrentPosition() method returns wrong position. When playing reaches its end and OnCompletionListener.onCompletion callback is called the current media player position is much higher than entire song duration.

任何想法解决这个？
