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 On Tue, Jun 23, 2009 at 3:34 PM, <kai.vehma...@nokia.com> wrote: > Hi, > > On 23 June 2009, Luo Cheng wrote: > >Can you specify which part of sofsip-cli media backend not > >working with new gstreamer?
