Hi Sakari, Thanks for the clarification. I will follow up with the contributor.

Minjung, Not using the camerabin based backend is not according to the MeeGo architecture. MeeGo camera adaptation interface IS gst camerabin. -sakari On 3/11/10 5:11 PM, "Shin Minjung (Nokia-MS-Qt/Brisbane)" <[email protected]> wrote: > Hi, > > Qt Mobility camera support prefers camerabin based implementation as backend > so that we do not need to have hardware specific implementation.
