Hi Conrad ,
Please pardon my ignorance , I am not so much aware of audio players as
such this is my first exposure to audio codecs . This is what I am looking
at , some audio player application that will expose some APIs ( I need to
use this to showcase an API testing tool and I thought it can be best
demonstrated using audio codecs ) which I can call to control the player ,
thats what you mean by control pipes I think ( if it is an IPC scenario ).
The player should be able to handle interfacing also , if you mean audio
file access .
So some .ogg files stored at some location should be possible to be
played and controlled by the APIs supplied by the .ogg player . I will use a
an automation tool on this software to call the APIs . The player
application should reside as a shared library for me to call the APIs ,
right now I am not planning to handle IPC scenarios . So want to use the
same user space to run mu automation tool and the music player as a shared
My board ( now a simulator ) is an ARM integrator 926 EJS board which
runs on Linux 184.108.40.206 . The board has a LM4549 Audio Codec IC connected
through a PrimeCell AACI. The LM4549 audio codec used on ARM’s development
boards has 18-bit ADCs and DACs. So in short without the ogg codec the board
can just record and play .wav files . Since I have a Linux port existing on
the board I hope that the .ogg player which I use should be able to use
standard calls to output audio through the codec .
Hope I have been able to explain the setup . Could you please advise .
