I guess the GStreamer mailing list is more likely to provide hints about making this work, you could also try jumping in the #gstreamer IRC channel on Freenode, they are very friendly people! >From what I can see, it seems that v4l2src is failing enumerating the standards defined by your driver (v4l2src could enumerate 20 standards but stopped at the 21st). The driver is supposed to return EINVAL when the index is out of bounds in the VIDIOC_ENUMSTD request (see http://v4l2spec.bytesex.org/spec/r9288.htm ) but, for some reason returns EPERM ? Hopefully, the GStreamer guys may have already encountered something similar. HTH, -- Damien -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com
