Hello,
I am a student at the University of Rennes 1, France. I just installed the
codec vlc compilation mode. I looked at the file omxil.c which you are the
author. I want to extract the quantization parameter QP. until now I have
not yet found. I find in the file OMX_Image.h, all data structures that
handle the compression process and understood QP. but these structures are
not used in the code of vlc. Please, do you have any ideas or a method to
extract this paramete, QP?
Thank you in advance.
