It's somewhere in kernel yes, but
'videoSurface->Lock(DSLF_WRITE, (void **)&dst, &pitch);'
is returning a wrong pitch value !.
Comparing the adresses written before sig11 happens
pixelformat I420 dst = 0x5067d000
y values done line dst = 0x5074c000
"y-done" - "y-start = 0xcf000 (847872 = 576 * 1472)
Thats like width = 736 in YUY2 format.
So by selecting YUY2 format instead of I420 format I got video
last night :-) .
softdevice code in SetParams:
// dlc.pixelformat = DSPF_I420;
dlc.pixelformat = DSPF_YUY2;
