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@letux:~# ./camera-demo sxga DISPLAY=3D:0 XAUTHORITY=3Dtcp 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=3D2 -tv = driver=3Dv4l2:device=3D/dev/video2:outfmt=3Duyvy:width=3D1280:height=3D102= 4:fps=3D15 -vo x11 MPlayer2 2.0-728-g2c378c7-4+b1 (C) 2000-2012 MPlayer Team Playing tv://.
