what's the maximum capacity of the sclr in dm8168

Intellectual 350 points

Hi, everyone.

I am working on DM8168 with DVR_RDK 4.0. My data flow is

ipcBitsOutHost-> ipcBitsInVideo->dec->ipcOutVideo-> ipcInVpss->scalar -> nsf-> ipcFramesOutVpss ->ipcFramesInDsp-> ALG

I want to input 8 channels 1080P/25 and slcr to 352X240/25,but when I input 4 channels I found after scalar the frame rate reduce to  20、21,5 channels to 14,6 channels to 10.

1、Is my requirement not realistic due to the sclr capacity?

2、I found there are 5 sclrs in the dm8168 chip,is it possible split the input to the sclr to improve the frame rate.for example:

                                                         |-----channel 0 1 2 3----sclr_link_sc5-----------------------|

8 channels 1080P/25---select-----                                                                                          merge----

                                                         |-----channel 4 5 6 7----dei_link_out_que_vip_sc------|
