Hi all.
We are using driver for imx477 on jetpack 4.5. We can open camera using gst-launch-1.0, but failed at using cv::videoCapture and appsink. It always said
[ WARN:0] OpenCV | GStreamer warning: Cannot query video position: status=0, value=-1, duration=-1
The gst command is
gst-launch-1.0 \
nvarguscamerasrc sensor-id=0 bufapi-version='TRUE' ! tee name=c0 \
c0. ! 'video/x-raw(memory:NVMM),width=4032,height=3040,framerate=30/1' ! nvvideoconvert ! queue ! tee
name=deep \
deep. ! nvvideoconvert ! nvv4l2h264enc insert-sps-pps=true iframeinterval=10 ! tee name=h264 \
h264. ! h264parse ! matroskamux ! filesink location=/home/nvidia/test_4k_video.mkv \
deep. ! nvegltransform ! nveglglessink sync='FALSE' -e
and the code in c++ is
string pipeline0 = "nvarguscamerasrc sensor-id=0 bufapi-version=true ! video/x-raw(memory:NVMM), width=4032, height=3040,framerate=30/1 ! nvvideoconvert ! queue ! video/x-raw, width=4032, height=3040, format=(string)BGRx ! videoconvert ! appsink";
Did you guys encounter this issue?
Best regards
