HDMI-CEC key mapping can be set in lib/driver/hdmi_cec.cpp (in source codes).But I do not think it's suitable for you, because then you have to build the own image.I think if you need to enigma not ignore code, it must be set in file hdmi_cec.cpp.
Hi, thanks for reply. Yes, you right. I've also found this driver as the right place to change. However, it is written in C++ so I would need to recompile the driver. I just thinking if it would be possible to just add this new keymapping there and commit into repository. Then it should be compiled in nightly build and available to everyone, am I right?. In fact there is only EXIT key mapped (44 0D) but not the return (8A 91). Maybe someone from OpenPLI developers could help as I'm not very keen in C++ and image compiling. Btw, I've found out that some mapping is also done in lib/python/components/HdmiCec.py. Wouldn't be possible to make the change here ? Thx.
