Hi,all

     my input video is :

                        SIZE: 1024 X 512

                        DEPTH:12bit

                        Pattern:YCbCr 4:2:2.

    the compressed image is gray viewing in kdu.

    1)properties of the image is :

                         Sprofile =PROFILE2

                         Scap = no

                         Sextensions = 0

                         Ssize = {1024,512}

                         Sorigin = {0,0}

                         Stiles = {1024,512}

                         Scomponents = 3,   this seems right

                         Ssigned = no,no,no

                         Sprecision = 12,12,12

                         Ssampling = {1,1},{1,2},{1,2}

                         Sdims = {1024,512},{1024,256},{1024,256}

                         Cycc = no

                         Cmct =0;

                         Clayers = 1

                         Cuse_sop = no

                         Cuse_eph = no

                         Corder = LRCP

                         Calign_blk_last ={no,no}

                         Clevels = 3;

                         Cads = 0;

                         Cdfs = 0

                         Cdecomp =B(-:-:-)

                         Creversible =no

                         Ckernels = W9X7

                         Catk = 0

                         Cuse_precincts = no

                         Cblk = {32,128}

                         Cmodes =0

                         Qguard =1

                         Qderived = no

                         Qabs_steps = 0.000928,.........

                         <<<<tile 0>>>> Canvas coordinates: v= 0:x= 0:height =

1024:width = 512


          any one can find out whats the matter ?

          2)the jp2 image can be changed into j2c image just change the

postfix,it still canbe viewed using kadu,and still grayscale, i think it's  a

little strange,isnt it?
