Hi
why is sizeof(HEVCVPS) is 7463476 ?
If you think about this for a moment, a VPS in the bit stream is what, 5 bytes ?
Now iam not even talking about someone proving you a 10mb file with a million VPSs
7TB allocation, memsets memcpies, ...
But even with a totally normal file 7mb is easily bigger than the frame buffer
that wastes memory, it wastes cpu time, it wastes data cache
thx
