Hi, does anybody know anything about subject? I needs to capture video data directly to another PCI device (not VGA card) using bus mastering (a la overlay method does). Device has mmap-ed IO memory which can be read/written by CPU. Data can be also transferred using overlay method directly (and it works), but there is no way to synchronize frames. "user pointers" method of a v4l2 API doesn't work with mmap-ed PCI device memory pointers. Leo.
