[gst-devel] Bug in osxaudiosrc? (Mac OS 10.5.5)

Fri Nov 14 03:01:48 CET 2008

Hi, gstreamer-devel:

    I have not Mac so I cannot test your problem. I'd like to get one but
Mac is expensive in China and seems that scratchbox cannot be installed on
Mac. I need a cross-compile environment so now Linux is the prefer OS for
me.

    Sjoerd, Maybe you should run this pipeline with root privilege? In
Linux, we use `sudo' to get root permission.
