Denise, What did you mean when you said that you had the integration of VIA's HW MPEG support for DirectFB in your pipeline?
I thought VIA's HW MPEG support was in the pipeline when DirectFB is used? Do you have a different mechanism to integrate VIA's HW MPEG support to reduce the CPU usage? Would you mind sharing it with us?
