Hi,
My customer wants to use CustomQ. But it seems the output is still effected by the value of Qvalue. Is that true?
If yes, what's the relationship between the Q table used in codec and CustomQ/Qvalue? If I set Qvalue to 97 (max), does the the code use the q table in CustomQ without change?
Chris
Which device/codec is this Chris ?

YD
Sorry, it seems the subject line had that info, will ask appropriate person to reply.
Hi Chris,
The DM365 will directly use the custom Q Matrix submitted by user. In a custom Q use case, the QValue parameter is ignored.
Regards,
Akshay
Akshay,
Need we do below control call to set the CustomQ before process?
IMG_Control((IIMGENC1_Handle)handle, JPEGENC_TI_ENCODE_SETCUSTOMQ, (IIMGENC1_DynamicParams *)&extn_dynamicParams, (IIMGENC1_Status *)&status);
Yashwant,
We made it work. We need to improve our JPEGenc user guide to add above info.
