sample_vpp.exe -lib hw can't work

Ritratto di Paul Yang

This is the command line:

sample_vpp.exe -lib hw -i megamind.yuv -o megamind.yuv

And the error return code from MFXInit turn out to be MFX_ERR_UNSUPPORTED.

But following can work:

sample_vpp.exe -lib sw -i megamind.yuv -o megamind.yuv

System:
Intel i5-2515E with 4GB RAM
Windows 7 Ultimate SP1 32-bit english
Intel Media SDK 3.0 beta4

Hi Paul,

The VPP sample was written to expose all VPP features up to Media SDK API 1.3. To simplify the code the API version was hardcoded to 1.3 in CreateFrameProcessor function inside sample_vpp_utils.cpp.

Media SDK API 1.3 HW acceleration will not be available until the driver release for the next generation Intel processor early next year. This also correlates with the release of Media SDK 2012 (3.0) Gold.

You can still use the VPP sample with HW acceleration by changing the API version to 1.1. However, keep in mind that if you try to use any VPP features related to the 1.3 API, it will fail.

Regards, Petter
