I have to evaluate the performance on Skylake and Haswell the Hardware decoding of HEVC.
"sample_decode.exe" have started with the following parameters .
sample_decode.exe h265 -i surfing.265 -o dummy -hw -p 33a61c0b4c27454ca8d85dde757c6f8e -f 30 -d3d -r
H.265 input file (surfing.265) was downloaded from the following URL.
I was compared to decode on Skylake and Haswell, more of Haswell was higher CPU utilization than Skylake.
I just saw the thread CPU utilization of sample_decode.exe in Process Explorer, had a higher thread of the CPU that are running the following .
However, such a thread does not exist when decoding on Skylake.
In addition , it looks like the above thread the bit rate of H.265 that input is high CPU utilization is high .
How can I do to lower the CPU utilization on Haswell?
My environment is as follows .
Intel Core i7-6700K CPU @4.00GHz
Intel HD Graphics 530
Intel Core i5-4590 CPU @2.00GHz
Intel HD Graphics 4600
