Re: [gst-devel] issue on gstreamer control

  Thanks
  It is much clear now.
  Still one question here?
  Do you really mean GstMixer *mixer = GST_MIXER
(sink); ?
  or, instead of sink, it should be ossmixer.

  I looked at the source, I didn't see osssink has
any mixer interface.

  Please correct me, thanks

Rong
