Sorry for late reply.
We still have no idea for this issue,
we used the gstreamer rtsp-server command to create pipeline:
./test-launch “nvcamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=1920, height=1080 ! omxh264enc bitrate=2000000 ! video/x-h264, profile=baseline ! rtph264pay name=pay0 pt=96”
and we see the gst-inspect-1.0 nvcamerasrc information:
exposure-time : Property to adjust exposure time.
This property will have effect only when Exposure mode is Off.
flags: readable, writable
Float. Range: 0 - 3.402823e+38 Default: 0.033
we cannot use this property since we need the auto exposure feature,
Could you have any idea to fix this problem?
The critical issue is when we in dark environment, the stream view have abnormal rainbow effect, this will make our recognition feature fail.
