Forum Post: Jpeg Quality

Hi, all!

       My version: DM8168, DVRRDK_04.00.00.03

       I get yuv420sp from nfs  and jpeg from encode, the I convert yuv420sp to bmp using my C code. I find that Jpeg qaulity is lower than bmp.  Then I view the code mcfw/src_bios6/links_m3video/iva_enc/encLink_jpeg.c, I changed value of qp, but it didn't work.

      My question: How can I get a high quality jpeg, which parameter can do it ?

 Thanks a lot.
