 Hi Developers.

 I have more as one sound players on my system mplayer, vlc, qmmp ...

 Each of em uses jack output , for example 2 independent instances of

 mplayer

 mplayer -ao jack  -srate 16000

 '/home/alf/mp3/mettwoch-de-doof-nuss.mpa.mp2'

 mplayer -ao jack  -srate 16000 '/home/alf/mp3/effeckt006.mp3'

 So far everything is excellent.

 How i do write my own DSP plugin for jack ?

 I wanna use my DSP plugin at this point, where all input channels are

 mixed together .

 How my plugin can ioctl() detect current samplerate,

 endianess, nr channels,

 samples interleaved or not, ... and maybe some more stream

 parameters.

 How do compile jack plugins ?

 What #include-s  must be used ?

 If my plugin will grow, and eat more and more CPU, how i prevent

 x-runs ?

 Is somewhere _simple_ C example how i can write jack plugins ?

 In simplest case -

 what is minimal program where i do each sample divide by 2

 ( or for 16bit short type just  shift  sample>>1 )

 Tnx in advance.

 Alf
