I am using Jetson Nano with accelerated GStreamer to record video using IMX219 sensor, using nvoverlaysink to preview video and nvv4l2h264enc to record h264 video.
Is there a way to simultaneously record and display what camera captures even if preview is at slower FPS?
Regards
Hi @tnano
You can use the tee element in gstreamer in order to split the data into multiple pads,
In your case something like this should work for you:
FILE_A=filenameA.mp4 gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM), width=1920, height=1080, format=NV12, framerate=30/1’ ! tee name=streams streams. ! queue ! nvv4l2h264enc bitrate=8000000 ! h264parse ! queue ! qtmux ! filesink location=$FILE_A streams. ! nvoverlaysink
You can find more pipelines like this in our wikis:
Please tell me if this works for you.

Works, Thank you
Hi @robertogs2,
I followed your syntax but I am getting error as follows:
WARNING: erroneous pipeline: could not link filesink0 to nvoverlaysink-nvoverlaysink0
I am using Jetson Xavier, arm64 , ubuntu 18.0.4. I have Leopard cameras. I tried for 1 camera to record and display video simultaneously but it didnt work
Command:
FILE_A=filenameA.mp4 gst-launch-1.0 nvarguscamerasrc sensor-id=0 ee-mode=0 ! “video/x-raw(memory:NVMM), width=1920, height=1080, format=NV12, framerate=30/1” ! tee name=streams streams. ! queue ! nvv4l2h264enc bitrate=8000000 ! h264parse ! queue ! qtmux ! filesink location=$FILE_A streams. ! nvoverlaysink
Can you please let me know. HOw to solve this issue?
