Re: [Sofia-sip-devel] problems with running sofsip-cli

Hi,

I found the problem is lack of gst plug-ins. I have gstreamer-0.10.18 on my
PC, and sofsip-cli works fine. But i have gstreamer-0.10.12 on my scratchbox
and n810 which seems do not have ALSA sink and source plug-in. But I am sure
I have both plug-ins-base.0.10.12 package on both environments. So I update
n810 with gstreamer-0.10.18 and gstreamer-plugin-base.0.10.18, and it seems
working fine without complaining couldn't find alsasink, but some plug-ins
still missing

.

The problem now is I am using VMPlayer on my PC, and i cannot
