BeagleBone Camera Cape and Gstreamer

GoogleGroups

Hi everyone,

I’ve bought a camera cape and I’d to turn my old BeagleBone to a remote camera which can capture images and send to a server. But I’m having a problem when capturing pictures using gstreamer-0.10, the captured images were very dark and I do not know what is the cause of this.

My gstreamer pipeline for image capturing:

gst-launch v4l2src device=/dev/video0 num-buffers=1 ! video/x-raw-yuv, width=800, height=600 ! ffmpegcolorspace ! jpegenc ! filesink location=1.jpg

during the process, I got an error

Src:v4l2src0:
system error: Inappropriate ioctl for device

Thank you.
