Memory size problem - HEVC HW encoder

[huanmo]

I'm testing the hevc hw encoder with media sdk sample for different resolution.  The measured memory for different resolution are listed as follow:

	Memory Size (MB)
Memory Type	1080p	720p	360p	180p	90p
System	97.1	60.1	40.2	34.2	32.9
d3d	83.6	48.3	29.4	23.4	22.2
d3d11	66.8	35	19.9	15.9	14.7

We found those values high, so I would like to know if the measured values are correct?

If not, is there any way to reduce those memory, especially for low resolutions?

My working environment  is decribed below:

os: Windows 10

cpu: Intel i7-8700 

gpu: Intel Graphics UHD 630

sdk: Media SDK 21.1.3

encoder cmd:  .\sample_encode.exe h265 -hw -w 320 -h 180 -n 4000 -async 1 -cqp -b 175 -num_active_P 1 -AvcTemporalLayers "1 2 4 0 0 0 0 0" -f 20 -i xxxx.yuv -nobref -r 1 -g 100 -gpb:off -o xxx.h265

Hi,

We tried running the command you shared from our side. We were able to run it successfully. Could you please share with us how did you calculated the measured memory for different resolutions.

Thanks and Regards

Hi,

The measured memory calculated from Windows Task Manager when media sdk sample was run for different resolutions.

In addition, 1080p means 1920x1080, 720p means 1280x720, 360p means 640x360, 180p means 320x180, 90p means 160x90.
