Starting with IPP 9.0, Intel has completely removed all JPEG-related functions including Huffman and color space conversions. Color space conversions I can handle on my own, but I am not in the mood to implement multi-threaded JPEG and Huffman parts from scratch. I had a working solution with UIC and IPP 8.x, now I have a broken build.
Sure, I can choose between staying on 8.x and miss on all performance improvements for new CPUs and all bugfixes / new features and upgrading to 9.0 while losing the most important part of my image viewer application -- (fast) JPEG decoding.
I would really appreciate some guidance from the Intel IPP product manager who decided to axe IPPJ domain on how to replace the missing functionality which was provided with it in previous IPP versions, preferrably in the shortest possible time span with minimal effort.
My requirements are quite simple -- multi-threaded JPEG decoding from memory stream. How to accomplish this using IPP 9.0?
