Hi!
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.
Ok, good.
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,

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.
I don't have that kind of acceleration working.
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?
Modules are tricky. I hate modules. I did patch with
All my testing so far was performed using modules, though it shouldn't
make difference.

https://lkml.org/lkml/2016/4/16/33
More stuff is needed, all those twl4030 regulator patches (already in
linux-next) + DTS initial-mode patch (https://lkml.org/lkml/2016/4/17/78).
+ the series. And yes, there seems to be explanation in the dmesg:

That usually happens when strobe is incorrect or there is no signal from
the camera.
Let me check the github...
I really hope I didn't miss something when I sent the series. May I have
your boot log?
