Or you can build it from source: git://linuxtv.org/v4l-utils.git >From the trace the format you encounter is GRBG, a bayered format that matches, V4L2_PIX_FMT_SGRBG8. It seems that these formats are not defined in GStreamer v4l2 support, though GStreamer has an element that may be able to convert that format, bayer2rgb. One could add this format to v4l2object.c and test against the converter to see if it's compatible, Patch would be appreciated. Note that libv4l will do the software conversion to more common formats. We don't know yet if HW specific color table are required, or included in libv4l, hence the reason we did not activate these formats.
