Hi Ashok, I managed to exchange raw data between 2 computers by using an FCP-like method and libraw1394. Mainly, I copied FCP code and extended it to allow data being transferred by chunks of 2k (instead of 512 bytes with bare FCP code). This was pretty easy. Problem is: there is a long delay between every data transfer and even with fast machines (Pentium III 450MHz) and I can't manage to get data transferred faster than 2.5 Mbytes/sec. By using Frank Bonin's implementation of IP-over-1394 (which use async transactions), I can ftp-transfer as fast as 15Mbytes/sec with slow machines (pentium 200MMX) so I guess I should be able to do as fast as him... I'm working on a way to speed-up transfer because I need at least 12Mbytes/sec. I think the problem is that the code waits for an acknowledge before sending another packet. If you have any other suggestions, please help.
