confusion about number of motion vectors fro H264

Hi,

   I tested the motion vectors fro H264 on DM368 platform.

the video resolution of encoder input is 720x480, if the motion estimation block size is 16x16, the number of motion vectors from H264 should be 45x30. However, when i print out the value of motion vectors, it looks like only 45x15 vectors have reasonable values, others are random values. why?

    Hi Bill,

    How are you using the motion vector. Are you decoding stream and checking or you are utilizing the motion vector and SAD output from encoder. Also when you say only 45x15 is valid. Are these 45x15 in beginning of the buffer or spread in the buffer of 45x30?

    With Regards,
