I've got some .MP4 video files that must be read in a VideoView in an Android activity. These videos include several audio tracks, with each one corresponding to a user language (eg. : English, French, Japanese...).
I've got unexpected trouble finding any help or documentation to provide such a feature. I'm currently able to load the video and play it in a VideoView with a MediaController, but not to change audio tracks.

I'm not sure the Android SDK provides any easy way to do this, which leaves me quite clueless on how to solve my problem. I was thinking of extracting every audio track, loading the audio that I want into a MediaPlayer depending on the language, then make audio and video play together. But I fear that some sync issues could arise and prevent me from doing this.

If you have any clue, any advice to help me getting started with this problem, you're more than welcome.

推荐答案

没有测试自己还，但似乎的 Vitamio 库中有多个音轨的支持（在其他有趣的功能）。这是API兼容 VideoView 从Android的类。

Haven't tested myself yet, but it seems that Vitamio library has support for multiple audio tracks (among other interesting features). It is API-compatible with VideoView class from Android.

也许你将不得不使用的 Vitamio 的 VideoView.setAudioTrack（）来设置音轨（例如基于区域）。见的 Vitamio API文档了解详细信息。

Probably you would have to use Vitamio VideoView.setAudioTrack() to set audio track (for example based on locale). See Vitamio API docs for details.
