I want to build gstreamer-1.0-sdk for android using cerbero.
I using the command as below:
1. git clone git://anongit.freedesktop.org/gstreamer-sdk/cerbero  [Execute OK.]
2. cerbero cerbero/config/cross-android.cbc bootstrap  [Execute OK.]
3. cerbero cerbero/config/cross-android.cbc package gstreamer-1.0-sdk [faild. ]
The log as below:
qys@his-Lenovo:~/cerbero/cerbero$ cerbero -c config/cross-android.cbc package gstreamer-1.0-sdk
WARNING: Using default configuration because /home/qys/.cerbero/cerbero.cbc is missing
