Vlcj audio only player
问题
我正在创建一个聊天应用，用户可以发送音频和视频文件。
对于我的视频文件，我已经成功在应用程序中创建了一个嵌入式视频播放器，可以播放任何视频。
但是对于我的音频文件，我不想使用带有vout=dummy选项的嵌入式视频播放器，相反我想要进行优化，并且使用DirectAudioPlayer来实现我的目的。我查看了MediaFactory的create方法，但是我不明白我应该如何为特定文件检索这些参数。
我想要的是在我的应用程序中只有一个直接的音频播放器，我可以将其用于多个音频文件，这种做法可行吗？
英文:
I am creating a chat application where the user can send audio and video files.
For my video files I have successfully created an embedded video player in my app which will play any video.
But for my audio files I don't want to use an embedded video player with options vout=dummy instead I want to be optimized and use an DirectAudioPlayer for my purposes. I took a look at the MediaFactory create but i don't understand how am I suppose to retrieve these parameters for an specific file.
What I want is just one direct audio player in my application which I can reuse for multiple audio files or is this not possible?

你可以使用HeadlessMediaPlayer。
这基本上与你已经在使用的EmbeddedMediaPlayer相同，但没有与显示视频有关的API。
但是需要注意，如果你通过HeadlessMediaPlayer播放视频，而不仅仅是音频文件，LibVLC将会打开一个本地窗口并播放视频 - 你可以通过通过MediaPlayerFactory传递"--no-video"来抑制这个行为。
当你想要在应用程序中访问音频缓冲区时，会使用DirectAudioPlayer - 也就是对本地音频缓冲区的“直接”访问。然后，你将不得不使用JavaSound或类似的东西来实际播放音频。所以我认为这不是你想要的。
英文:
You can use a HeadlessMediaPlayer.
This is basically the same as the EmbeddedMediaPlayer that you're already using, but with no API to do with displaying the video.
A word of caution though if you play a video through the HeadlessMediaPlayer, rather than just an audio file, LibVLC will open a native window and play the video - you can suppress this by passing "--no-video" via the MediaPlayerFactory.
The DirectAudioPlayer is used when you want to access the audio buffer in your application - i.e. "direct" access to the native audio buffer. You would then have to use JavaSound or something to actually play the audio. So I don't think this is what you want.
