a window in SWMS , see the gray covered in the video above.

hi,all:

env: dm8168 and dvr rdk 4.0

chains: cap-enc-dec-sw-dis.

Capture: camera.

Sometimes, I could see the gray covered in the video above。

 

                 

When  waving hands, can clearly see the changes in the window:

when I deleted this decode channel ,then ,created other decode channel , video display is normal.

 

how I might resolve these issues? Thanks.
