They are very inefficient as they + come with high interrupt load and several layers of callbacks for each + packet. Because of these deficiencies, the video1394 and dv1394 drivers + and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created. + +Users: + libraw1394 users via the long deprecated API raw1394_iso_write, + raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv + + libdc1394, which optionally uses these old libraw1394 calls + alternatively to the more efficient video1394 ABI |
