InputStreamAudio: fix channels error when decode stream

Clement Champetier · Clement Champetier · commit b323cc4c1af1 · 2014-06-02T11:55:21.000+02:00
* InputStreamAudio: update constructor to indicate number of channels of
the CodecContext.
* AudioDesc: add getters for channels, sample rate and sample format.
