* Compliant components will prepopulate this structure with optimal
* values during the OMX_GetParameter() command.
*
* STRUCT MEMBERS:
* cMIMEType : MIME type of data for the port
* pNativeRender : Platform specific reference for a display if a
* sync, otherwise this field is 0
* nFrameWidth : Width of frame to be used on port if
* uncompressed format is used. Use 0 for
* unknown, don't care or variable
* nFrameHeight : Height of frame to be used on port if
* uncompressed format is used. Use 0 for
* unknown, don't care or variable
* nStride : Number of bytes per span of an image (i.e.
* indicates the number of bytes to get from
* span N to span N+1, where negative stride
* indicates the image is bottom up
* nSliceHeight : Height used when encoding in slices
* bFlagErrorConcealment : Turns on error concealment if it is supported by
* the OMX component
* eCompressionFormat : Compression format used in this instance of
* the component. When OMX_IMAGE_CodingUnused is
* specified, eColorFormat is valid
* eColorFormat : Decompressed format used by this component
* pNativeWindow : Platform specific reference for a window object if a
