I tried that too, you will need to change many of the is_bt656 into is_fldmode. For isp configuration it seems that the only difference between the two is (more or less) just the REC656 register. I made a hundred attempts and in the end i had a quite working capture (just not centered) but ghosting always there. I made another test and by luck i got a strange thing, look at the following image: http://postimage.org/image/2d610pjk4/ (It's noisy because of a hardware problem) I made it with these changes: //ccdc_config_outlineoffset(ccdc, pix.bytesperline, EVENEVEN, 1); ccdc_config_outlineoffset(ccdc, pix.bytesperline, EVENODD, 1); //ccdc_config_outlineoffset(ccdc, pix.bytesperline, ODDEVEN, 1); ccdc_config_outlineoffset(ccdc, pix.bytesperline, ODDODD, 1); So you have an image with a field with no offset, and a field with offsets. Now if you look between my thumb and my forefinger behind them there's a monoscope picture and in one field you can see 2 black squares, in the other one you can see 3 black squares. So the two field that will be composing a single image differ very much. Now the questions are: is this expected to happen on an analogue video source and we can't do anything (apart from software deinterlacing)? is this a problem with tvp5150? Is this a problem with the isp?
