screen flicker on rockchip platform. #3

Open hisilic opened 5 years ago

Hi, I had tried this project on rockchip platform using h264_rkmpp decoder. The screen flickered and only few frame can be displayed. I have tried to add time-delay(about 20ms) between drmModeSetPlane and drmModeRmFB. Then the flicker alleviated. I know the modification above is not a good method and i want to resolve the flicker problem in a appropriate way. Can you help me? Thanks!
