We did have yet another (non-DT) camera driver and media-ctl working in with 3.12.37, but had no success yet to update it to work with modern kernels or drivers. It is either that the (newer) drivers missing something or the media-ctl has changed. Here is the log of our scripts with Hugues' driver and our latest setup: root at letux:~# ./camera-demo sxga DISPLAY=:0 XAUTHORITY=tcp Camera: /dev/v4l-subdev8 Setting mode sxga media-ctl -r media-ctl -l '"ov965x":0 -> "OMAP3 ISP CCDC":0[1]' media-ctl -l '"OMAP3 ISP CCDC":1 -> "OMAP3 ISP CCDC output":0[1]' media-ctl -V '"ov965x":0 [UYVY2X8 1280x1024]' media-ctl -V '"OMAP3 ISP CCDC":0 [UYVY2X8 1280x1024]' media-ctl -V '"OMAP3 ISP CCDC":1 [UYVY 1280x1024]' ### starting mplayer in sxga mode ### mplayer tv:// -vf rotate=2 -tv driver=v4l2:device=/dev/video2:outfmt=uyvy:width=1280:height=1024:fps=15 -vo x11 MPlayer2 2.0-728-g2c378c7-4+b1 (C) 2000-2012 MPlayer Team Playing tv://.
