I am trying to control exposure on a usb web cam that I’m pulling from with a gstreamer pipeline using the v4l2src plugin. gst-inspect doesn’t show any exposure control available for v4l2src. I’m also not able to see the exposure parameter using something like v4l2-ctl.
You may try to see what is available from qv4l2 (can be installed from apt). Be sure to disable bypass, it may interfere with nvcamera-daemon.[EDIT: this wouldn’t apply for a USB cam]
Hi Jerry,
I am using PiCamera(CSI camera) with a gstreamer pipeline using v4l2src plugin and I can’t find any control to set the exposure time/other exposure params. Can you help me out with this?
we had done the implementation to control gainRange, and exposureTimeRange with Argus plugin. please expect this will be include in the next public release.
you may also refer to Topic 1033150 for more details.
thanks
From what I understand you’ve done the implementation for nvarguscamerasrc plugin, but I am trying to use the v4l2src plugin for my application. Can you help me with how to set exposure parameters using v4l2 plugin?
(Note: I am using PiCamera with Tinker Board.)
Thanks!
