Hi!
Ok, let me try:
The needed pipeline could be made with:
media-ctl -r
media-ctl -l '"vs6555 binner 2-0010":1 -> "video-bus-switch":2 [1]'
media-ctl -l '"video-bus-switch":0 -> "OMAP3 ISP CCP2":0 [1]'
media-ctl -l '"OMAP3 ISP CCP2":1 -> "OMAP3 ISP CCDC":0 [1]'
media-ctl -l '"OMAP3 ISP CCDC":2 -> "OMAP3 ISP preview":0 [1]'
media-ctl -l '"OMAP3 ISP preview":1 -> "OMAP3 ISP resizer":0 [1]'
media-ctl -l '"OMAP3 ISP resizer":1 -> "OMAP3 ISP resizer output":0 [1]'
media-ctl -V '"vs6555 pixel array 2-0010":0 [SGRBG10/648x488 (0,0)/648x488 (0,0)/648x488]'
media-ctl -V '"vs6555 binner 2-0010":1 [SGRBG10/648x488 (0,0)/648x488 (0,0)/648x488]'
media-ctl -V '"OMAP3 ISP CCP2":0 [SGRBG10 648x488]'
media-ctl -V '"OMAP3 ISP CCP2":1 [SGRBG10 648x488]'
media-ctl -V '"OMAP3 ISP CCDC":2 [SGRBG10 648x488]'
media-ctl -V '"OMAP3 ISP preview":1 [UYVY 648x488]'
media-ctl -V '"OMAP3 ISP resizer":1 [UYVY 656x488]'

Linux n900 4.6.0-rc5-176733-g8b658a3-dirty
media-ctl from today's git.
and tested with:
mplayer -tv driver=v4l2:width=656:height=488:outfmt=uyvy:device=/dev/video6 -vo xv -vf screenshot tv://
I can't do -vo xv ... fails for me, probably due to X
configuration. Does it work with -vo x11 for you?
yes, -vo x11 works under maemo.
In linux-n900 branch we have a patch that reserves memory for omapfb -
see
https://github.com/freemangordon/linux-n900/commit/60f85dcb6a663efe687f58208861545d65210b55
also, because of a change in 4.6,
https://github.com/freemangordon/linux-n900/commit/60f85dcb6a663efe687f58208861545d65210b55#diff-072444ea67d2aca6b402458f50d20edeR125
needs a change to DMA_MEMORY_IO and the if bellow needs the relevant
change as well.
This is needed for -vo xv (and any omapfb video playback) to reliably
work under maemo.
For me it shows window with green interior. And complains about v4l2:
select timeouts. (I enabled these in .config):
+CONFIG_VIDEO_BUS_SWITCH=y
+CONFIG_VIDEO_SMIAREGS=y
+CONFIG_VIDEO_ET8EK8=y
+CONFIG_VIDEOBUF2_CORE=y
+CONFIG_VIDEOBUF2_MEMOPS=y
+CONFIG_VIDEOBUF2_DMA_CONTIG=y
+CONFIG_VIDEO_OMAP3=y
+CONFIG_VIDEO_SMIAPP_PLL=y
+CONFIG_VIDEO_SMIAPP=y
Any ideas?
Pavel
Try to build those as modules. Also, do you have all the needed patches
besides those in the patchset?
See https://github.com/freemangordon/linux-n900/commits/v4.6-rc4-n900-camera
Also, is there anything related in dmesg log?
