I used gentle reboot protocol when i change the vim crop.
It was 1080p60 to 1080p60.
VSP_set_PVSP_ENABLE_VIM(0); //step 1
VSP_set_PVSP_LOCK_VOM(1); //step 2
VSP_set_PVSP_ENABLE_FFS(0); //step 3
VSP_set_PVSP_ENABLE_FFS(1); //step 5
VSP_set_PVSP_ENABLE_VIM(1); //step 6
VSP_set_PVSP_LOCK_VOM(0); //step 7
When the step 5 had gone,the color bar was normal. Like the picture.
when i enable the vim(step 6),the color bar was oblique. Like the picture.
When the step 7 had gone,the color bar was normal.
Can you tell me the reason?
if i want to scale the input picture gradually from 100% to 10%, how can i do?
In"1080p to 480p(16:9) using ADV8003 scaler",JeyasudhaMuthuPerumal said that "to get the smooth change, it is recommended first to disable the VOM (0xE828  = 0), then to change the Crop settings, then to enable the VOM (0xE828  = 1)". I have tried to set VOM but the color bar also was tilted.
