问题
At the beginning of this year, I tried to implement an android-app which could stream ALL system-audio to a remote system.
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.
But it was a bit buggy and hard to release.
So I stopped work on it.
But now, some months later I wonder if it is possible to:
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.
Anyone an idea?
回答1:
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.
You might try looking into using PulseAudio as a replacement for Android's AudioFlinger, as Pulse offers a loopback module for Linux at least.
