安卓：可以蓝牙连接的自我？ [英] Android: Possible to connect bluetooth to self?

问题描述

在今年年初，我试图实现一个Android的应用程序，它会流中的所有系统的音频到远程系统。

At the beginning of this year, I tried to implement an android-app which could stream ALL system-audio to a remote system.

这是不容易的，因为（当时）有没有办法让所有系统的音频。 所以，我开发了一个内核模块，它劫持的声音。

This was not easy because (at that time) there was no way to get all system-audio. So I developed a kernel-module which hijacked the audio.

但它是一个有点马车，难以释放。

But it was a bit buggy and hard to release.

因此​​，我停止工作就可以了。

So I stopped work on it.

但现在，几个月后，我不知道是否有可能：

But now, some months later I wonder if it is possible to:

通过蓝牙对自己（=模拟蓝牙）连接，因为那时我   可以通过API转发系统，音频，然后把它拿来另一   一面。

Connect via bluetooth to myself (= simulate bluetooth), because then I can forward system-audio to it via API and then fetch it on the other side.

任何人的想法？

推荐答案

我对此表示怀疑。一对夫妇的原因是没有回环设备的蓝牙（见这里也可以），你将基本上需要使用

I doubt it. For a couple of reasons there is no loopback device for Bluetooth (see here also), which you would basically want to use.

您可以尝试寻找到使用的PulseAudio作为替代Android的AudioFlinger，脉冲提供了Linux的回送模块最少。

You might try looking into using PulseAudio as a replacement for Android's AudioFlinger, as Pulse offers a loopback module for Linux at least.
