I ran camera-demo (which runs camera-setup) terminated it and then
started capture directly.

Now I tried a bit around:

iff --git a/Letux/root/capture.c b/Letux/root/capture.c
index 03a798982fba..2a24c86766ac 100644
--- a/Letux/root/capture.c
+++ b/Letux/root/capture.c
@@ -519,7 +519,7 @@ init_device                     (void)
         fmt.fmt.pix.height      = 1024;
 //        fmt.fmt.pix.pixelformat = V4L2_PIX_FMT_YUYV;
                fmt.fmt.pix.pixelformat = V4L2_PIX_FMT_UYVY;
-        fmt.fmt.pix.field       = V4L2_FIELD_INTERLACED;
+        //fmt.fmt.pix.field       = V4L2_FIELD_INTERLACED;
 

gets me a bit further. If I start ./capture -d /dev/video2 
I get this:
# ./capture -d /dev/video2
