Detailed Description

Jack Application.

Author
Russell Bryant russe.nosp@m.ll@d.nosp@m.igium.nosp@m..com

This is an application to connect an Asterisk channel to an input and output jack port so that the audio can be processed through another application, or to play audio from another application.

handle jack audio

Parameters
[in]chanThe Asterisk channel to write the frames to if no output frame is provided.
[in]jack_dataThis is the jack_data struct that contains the input ringbuffer that audio will be read from.
[out]out_frameIf this argument is non-NULL, then assuming there is enough data avilable in the ringbuffer, the audio in this frame will get replaced with audio from the input buffer. If there is not enough data available to read at this time, then the frame data gets zeroed out.

Read data from the input ringbuffer, which is the properly resampled audio that was read from the jack input port. Write it to the channel in 20 ms frames, or fill up an output frame instead if one is provided.
