Only MPEG2 video for VDPU2 works. And it need a patch to fill the QP table. I have finished the register table of the rkvdec and rk hevc decoder. But I can't feed its proper input stream, I will talk the reason below. The slice header reconstruction is not acceptable, even I don't care about VP9 now, the reference picture set for HEVC is very complex.
