The data structures for VP9 in mfxvp9.h is wrapped by MFX_VERSION_NEXT, which means those data structures have never been used in a public release. Actually MFX_CODEC_VP9 and other VP9 stuffs are added in mfxstructures.h. In addition, mfxdefs.h is included in mfxvp9.h, so we may use the check in this patch for MFX_CODEC_VP9 This is in preparation for oneVPL support because mfxvp9.h is removed from oneVPL [1] [1]: https://github.com/oneapi-src/oneVPL
