My code has
s_cameraVideoStreamType = DJI_CAMERA_VIDEO_STREAM_TYPE_H264_CUSTOM_FORMAT;

I'm wondering that it have something relation with this error.

Thank you for your reply.

My payload needs to monitor the camera in real-time.
The H264_CUSTOM_FORMAT method is much familiar than DJI-H264 way in my project.
My project has another process to send the video stream with gstreamer.

I strongly hope that the wizards in DJI will fix this problem soon✨
I back to 3.8.1 until the problem will be fixed.
