When using the following command with the gstreamer-nvargus library to capture videos, the resulting frames are all completely black. When aelock = 0, the video capture works normally.
gst-launch-1.0 -e nvarguscamerasrc sensor-id=1 aelock=1 exposuretimerange=“200000 200000” gainrange=“1 1” num-buffers=200 ! ‘video/x-raw(memory:NVMM), width=2880, height=1860, framerate=20/1, format=NV12’ ! queue ! nvvidconv ! nvv4l2h265enc ratecontrol-enable=0 quant-i-frames=30 quant-p-frames=30 ! h265parse ! mp4mux ! filesink location=sn4_aelock_cam1_n.mp4 -v
hello smadhavan,
could you please have another try with higher gain value, such as 100?
Hi Jerry!
I tried setting higher values for gain as you suggested. The issue stays the same with it. =
Both single frame image capture and video capture returns blacked out frames with aelock = 1
hello smadhavan,
I can see different capture results with aelock=0/1 via gst pipeline, but I don’t see completely black frames issues.
and… AE Lock it works normally by running with argus_camera application to toggle the settings.
anyways, let me arrange resources to investigate this internally.
hello smadhavan,
furthermore, this may due to sensor init settings.
could you please contact with sensor vendor to confirm those sensor init register settings.
