I used composition in sample_vpp ,but failed .
When I called MFXVideoVPP->QueryI, it return 4 (MFX_WRN_PARTIAL_ACCELERATION)。
as the title described, I tryed to decode a hevc stream(resolution 4800x3840) larger than 4k size on skylake platform , by using ffmpeg + vaapi , only the left upper corner of the picture is decod
use the Intel display driver version 24.20.100.xxxx(20180425 – 20180620) to do the vpp process, the performance is bad than the 220.127.116.1144(2018-02-04). Is there any change in the new driver?
initPar.Version.Major = 1; initPar.Version.Minor = 0; initPar.GPUCopy = 0;
When i use the code below, i found that, the memory used by my application will increse 200KBytes ~ 800KBytes after every call .
How can i fix it ?
