audio-streaming

问题 I've been trying to stream mp3's over http using Android's built in MediaPlayer class.

问题 I was wondering if it is possible to read data that is going from the sound card to the speakers with the PortAudio API. After looking through the documentation, I found an example (http://portaudio.com/docs/v19-doxydocs/paex__record_8c_source.html) where they read data from the microphone. However, I would like to be able to capture the audio that is coming from the sound card. Is there a way to do this in PortAudio and if not please point me in the right direction. Also, it is important

问题 I am building a radio app in BB 5. I have a .pls url where I find my urls to play the stream. My issue is. I need to build a Buffer to play this stream because the file which is downloaded is too big to play it inmediatly, but I don't know how to build this buffer. Any idea?
