Includes index and video extension headers
in order to support vpx specific parameters
and enable vpx encoder.
Note that existing (seemingly modified) version
of OMX_Video.h semantically conflicts with
official OMX_VideoExt.h because former includes
OMX_Video_CodingVPX as OMX_VIDEO_CODINGTYPE
whereas official extension headers denote
it as OMX_VIDEO_CodingVP8 within
OMX_VIDEO_CODINGEXTTYPE.
