Add algorithm on dsp link

         I want to add my own algorithm on dsp.

        so I wrote a simple example .

        The Fuc of example is  "Remove 120 lines in the middle of the video frame" like 1920x1080->1920x960

    (YUV 420 SP    y:pFrame->addr[0][0], uv pFrame->addr[0][1])

     Question: How can I get the right resolution(1920x960).

               I watched the encoded image. The  resolution of encoded video is 1920x1080( Not 1920x960)

              I changed  " System_LinkChInfo  -->height (1080->960)"  but it dos't worke.
