How to run DVR RDK of DM8148 on a DM8127 camera?

Ming-Lin Kao

Intellectual 450 points

I used to work on DM8168, but recently I got a DM8127 camera. Then I tried to run DVR RDK on this camera with the configuration of DM8148. It is strange that the performance is low: enc 1920x1080x23fps + dec 1920x1080x23fps. I think that would be 30fps.

How should I do to improve its performance?

===============================

ARM clk: 600MHz

DSS Default OFF

I modified the data read and the number of decod buffers, and recycle buffers more often. Then it got 30 fps now.

Hi Ming-Lin Kao,

I using DM8127 IP camera reference design, have you changed anything in the DVR RDK to port it on DM8127?

Is there are minimal changes in DVR RDK?

Please help me.

Thanks and Regards,

Kiran

It may be some driver issues.
