Re: [Vala] Gstream Capture audio from microphone

[Alexandre Rosenfeld <alexandre rosenfeld gmail com>]

The GStreamer pipeline can be as simple as "autoaudiosrc ! audioconvert !
vorbisenc ! oggmux ! filesink location=dump.ogg".
And you can use something as simple as this code below to run a GStreamer
pipeline inside your app (adapted from another email I sent a few days ago):

   1. using Gst;
   2.
   3. void main (string[] args) {
   4.     Gst.init (ref args);
   5.
   6.         var pipeline = Gst.parse_launch("autoaudiosrc ! audioconvert
   ! vorbisenc ! oggmux ! filesink location=\"%s\"".printf(args[1]));
   7.     pipeline.set_state (State.PLAYING);
   8.     new MainLoop ().run ();
   9. }
   10.


If you need more control, then you need to learn a bit more of GStreamer
and then you can control the pipeline elements in your code.
