The issue of video brightness loss in H264 hardware encoder
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"
