[gst-devel] VIDIOC_S_CTRL with GStreamer

[John Buckley]

Hello, 
I would like to set the V4L2 zoom and focus controls on a compatible camera while using a Gstreamer pipeline to stream video. 

I see the documentation on how to get and set the controls using VIDIOC_G_CTRL & VIDIOC_S_CTRL commands but this assumes that you have opened a connection using v4l2-open and have a file handle to the v4l2 camera. 

Can v4l2 commands to set control values be sent while a Gstreamer pipeline is active?
