Hi,<BR>
<BR>
I am trying to implement FMO Type 1 (checkerboard pattern with only 2 slice groups) in x264.<BR>
I just used two slices per frame and then I wrote all white MBs into the first slice and <BR>
black MBs to the second slice. I also added the required information to the PPS.<BR>
To check the correctness of my implementation, I used JM (which supports FMO) but unfortunately<BR>
my first try led to a crash. I think the problem is related to the fact that when we use a<BR>
checkerboard pattern, always, all left and top neighbours are unavailable but during the encoding<BR>
process, x264 encodes MBs based on these neighbours while during the decoding process, these<BR>
neighbours are not available. But what do you think? Anyway, to implement FMO in x264, which steps<BR>
are necessary? Thanks in advance!<BR><br /><hr />Get news, entertainment and everything you care about at Live.com. <a href='http://www.live.com/getstarted.aspx ' target='_new'>Check it out!</a></body>
