Man Dai

Other Parts Discussed in Thread: TMS320DM6446

In the "De-Interlacing and YUV 4:2:2 to 4:2:0 Conversion on TMS320DM6446 Using the Resizer", it said "The exact value of delta is calculated by some internal mathematical equations in the resizer and is not explained in this document. However, it can be obtained using an offline utility program, which will be released with the production version of the resizer driver."

But I cannot find the offline utility program, my linux kernel is 2.6.10

Thanks!!!

    Hi All

    I find the calccoef,but how do I can transfer my YUV422 720x576 data to YUV420 352x288.

    through ./calccoef -i 720x576 -o 352x288 ,I get some data. the hrsz is 520, the vrsz is 510.

    ./calccoef -r 520x510 -o 352x288 -s 2880 -p ,I get  the resizer_params.inptyp = RSZ_INTYPE_YCBCR422_16BIT, the resizer_params.pix_fmt = RSZ_PIX_FMT_YUYV, the params is YUV422 --->YUV422, why not    RSZ_INTYPE_PLANAR_8BIT and RSZ_PIX_FMT_PLANAR

    Thanks!!!
