Aron Sogor，您好！ 1.Of course yuo need to use some lib to access Audio A/O. 2.You can make a API from Madlld, like MadCreate(),MadDecode(),MadDelete() 3.It do need to use MadFixedToSshort, convert Output form Int to Short.

Hmmm...
Interesting, a couple of things that I wonder about that idea: 1. madlld does not access the sound device- as writing to the sound device would be either piped to sox or use something like libao.
2. looking at the source it seems madlld "pulls" the frames and controlls the loop vs in madplay mb calling the decoder it uses callback where libmad sort of "push" the frames. ?? is that a valid observetion ??
3. finally there is the MadFixedToSshort function that turns the decoded mad frame to PCM that seems to be the "magic" each app mention that could be done better... What is it's significance and why do mortals care?
Thanks for replying my mail...
Aron

Hi,
Sorry if I am asking the obvious.
Is there a way to compile madplay into a shared library?
I am looking for a way to embed madplay in an application and provide new controlls other than tty.
The other option would be to do an exec() and controll it over stdin/stdout but that is not very elegant.
Any suggestions?
Aron
