After using argus_camera utility to view video, can't capture frames with v4l2-ctl --stream-mmap

When using V4L API, you would have to use flag :

--set-ctrl bypass_mode=0

The bypass mode is used by argus, and you may fool it if not disabling it.
Note that if it gets wrong you can restart its daemon:

sudo systemctl restart nvargus-daemon.service
