3487 | * and set up the bottom field in the logic | |
3488 | * below. Don't ever do the top field. This | |
3489 | * of course means that if we set up the | |
3490 | * bottom field in the above code that we'll | |
3491 | * actually skip a field. But that's OK. | |
3492 | * Having processed only a single buffer this | |
3493 | * time, then the next time around the first | |
3494 | * available buffer should be for a top field. | |
3495 | * That will then cause us here to set up a | |
3496 | * top then a bottom field in the normal way. | |
3497 | * The alternative to this understanding is | |
3498 | * that we set up the second available buffer | |
3499 | * as a top field, but that's out of order | |
3500 | * since this driver always processes the top | |
3501 | * field first - the effect will be the two | |
3502 | * buffers being returned in the wrong order, | |
3503 | * with the second buffer also being delayed | |
3504 | * by one field time (owing to the fifo nature | |
3505 | * of videobuf). Worse still, we'll be stuck | |
3506 | * doing fields out of order now every time | |
3507 | * until something else causes a field to be | |
3508 | * dropped. By effectively forcing a field to | |
3509 | * drop this way then we always get back into | |
3510 | * sync within a single frame time. (Out of | |
3511 | * order fields can screw up deinterlacing | |
