And secondly, I have tried to add some SXGA config and it looks good by oscilloscope: - XCLK ca. 24 MHz - PCLK ca. 12 MHz - HREF ca. 15.6 kHz negative going impulses - VSYNC ca. 15 Hz (fps) positive going impulses - D8 data line shows changing 0/1 patterns which depend on light falling in camera lens But mplayer still shows a green screen and reports v4l2: select timeout. I assume we should see a at least scrambled image but not a green screen, even if sync position and polarity or data format would not be correctly set up. This time the omap3isp is fully initialized and does a register dump: > root@letux:~# ./camera-demo sxga > 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 NOTE: /dev/video2 is $(media-ctl -e "OMAP3 ISP CCDC output") > MPlayer2 2.0-728-g2c378c7-4+b1 (C) 2000-2012 MPlayer Team > > Playing tv://. > Detected file format: TV > Selected driver: v4l2 > name: Video 4 Linux 2 input > author: Martin Olschewski > comment: first try, more to come ;-) > v4l2: ioctl get standard failed: Invalid argument ^^^ does not look harmful > Selected device: OMAP3 ISP CCDC output > Capabilities: video capture video output streaming > supported norms: > inputs: 0 = camera; > Current input: 0 > Current format: unknown (0x0) > tv.c: norm_from_string(pal): Bogus norm parameter, setting default. > v4l2: ioctl enum norm failed: Inappropriate ioctl for device ^^^ does not look harmful > Error: Cannot set norm!
