[gst-devel] issue on gstreamer control

[rong wang]

 Hi, Ronald
   Thanks for your quick answer. It is much clear now.
however, I believed you misunderstand one of my
questions. I saw the file gstossmixer.c, but it is one
of three elements in the ossaudio (osssink,osssrc,
ossmixer). I can see it
from gstossaudio.c, but I cannot see anywhere how
osssink is related to ossmixer. 


Thanks

Rong
