I try to implement a driver of ADV7401 based on ADV7180

I can get a video (very poor quality but it work) in GATED_MODE (p->u.bt656.clock_curr = 27000000;)

but i want to be in BT656 mode (p->u.bt656.clock_curr = 0;)


I have check the frames with scope all EAV/SAV code are OK.


When i am in BT656 mode, when i launch gstreamer i have a timeout error :

v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0


Does Interlaced BT656 mode work for kernel 3.0.35 ?


Thanks for your help !
