DM36x JPEGenc: CustomQ vs Qvalue
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?
Which device/codec is this Chris ?
Sorry, it seems the subject line had that info, will ask appropriate person to reply.
The DM365 will directly use the custom Q Matrix submitted by user. In a custom Q use case, the QValue parameter is ignored.
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);
We made it work. We need to improve our JPEGenc user guide to add above info.
