After my video data is encoded by H264 hardware, the picture becomes darker. This issue doesn't occur when displayed directly. Both the ISP and the camera preview are normal. I need some help.
board : stm32mp257f-eval
camera: imx335
hardware encoder parameters : encodebin profile="video/x-h264|element-properties,keyframe-interval=5,rate-control=0,qp-min=20,qp-max=20"
