Hi Jean-François, I've added on our tree a DocBook patch that helps to detect the gaps between the videodev2.h header and the specs. It is complaining that a symbol is missing: Error: no ID for constraint linkend: V4L2-PIX-FMT-JPGL. According with videodev2, this is a "JPEG-Lite" FOURCC: include/linux/videodev2.h:#define V4L2_PIX_FMT_JPGL v4l2_fourcc('J', 'P', 'G', 'L') /* JPEG-Lite */ This were introduced by this commit: commit ce5b2acce60405b938d1f1f994024cde4e2cdd7e Author: Jean-François Moine <moinejf@xxxxxxx> Date: Mon Mar 14 08:49:28 2011 -0300 [media] gspca - nw80x: New subdriver for Divio based webcams Could you please provide us the proper documentation for the new symbol? Thanks!
