Andreas, When I was developing the FPGA encoder for different JP4 flavors I used modified libjpeg - it had a lot of debug output that I needed to troubleshoot encoder. The state of my modification was not really usable for anything but encoder development, I believe Paulo has now more usable code.
On the other hand, Jp4-hdr advantage over jp4/ (and even jp46) is just better compression (smaller file size for the same quality), the most challenge of decoding it is not the decoding of the format (you may start with JP46 and ImageJ plugin), but de-mosaic algorithm combined with processing of 2 different greens. And it has to be done in a single step - you need a modified de-mosaic algorithm that is aware of those gains. When that part will work - you can get back to the format and get some extra compression ratio.
