We may create it as a next iteration of the patch. Right now we can't print available codecs on about:support for NIVIDIA but given it's state I don't think it so big deal. I'm looking to enable VA-API by default which means we can't generate coredumps on NVIDIA systems. GfxInfo.cpp just reads data from remote process (which crashes on broken NVIDIA), that's not the detection itself.
