H.264 full range encoding,decoding and conversion to/from RGB4
I am using Intel Media SDK 1.19 on Windows. Currently I try to figure out
1. How to convert an image from RGB4 to NV12 color space with "full range" color values I tried to use the mfxExtVPPVideoSignalInfo as extended parameter at the VPP initialization, but then the Init call always returns error -14 (MFX_ERR_INCOMPATIBLE_VIDEO_PARAM).
