hi, can any one tell me if  VDCE can works in the following situation?  How to config the VDCE parameters?

Y  1280 * 720 , paded with 32 pixes for each side

C 1280 * 720 , paded with 32 pixes for both left and right side , but 16 pixes for top and down side.

we are using linux ,  and  we  are sure that VDCE works if  C is also paded with 32 pixes for each side.

    What platfrom are you using (DM355, DM644X, DM6467, DM643X...)?   I am not very familiar with VDCE but can get you the information you need.

    Hi,

     

    VDCE driver is available only on the DM6467 platform.

    I don't get the exact problem but VDCE supports line offset for the entire frame and user buffer exchange mechanism. Using these features, we can have a strip on the left as well as on the right hand side of the image. If you want to leave few lines in the top of the image, you can use user pointer buffer exchange mechanism and provide exact offset of the image as pointer to the VDCE. For the bottom lines, you can provide size of the buffer larger than size of the image to leave bottom part of the buffer. This padding/offsets is same for both Y and C but it is not possible to give different offsets for Y and C

     

    Thanks,
