6 Defines and manages objects that decode video.
The NvMediaIDE object decodes compressed video data, writing the results to a target.
A specific NvMedia implementation may support decoding multiple types of compressed video data. However, NvMediaIDE objects are able to decode a specific type of compressed video data. This type must be specified during creation.

| typedef void NvMediaPictureInfo |
A generic "picture information" pointer type.
This type serves solely to document the expected usage of a generic (void *) function parameter. In actual usage, the application is expected to physically provide a pointer to an instance of one of the "real" NvMediaPictureInfo* structures, picking the type appropriate for the decoder object in question.

| typedef void NvMediaRefSurface |
A generic "reference surface" pointer type.
This type serves solely to document the expected usage of a generic (void *) function parameter. In actual usage, the application is expected to physically provide a pointer to an instance of NvSciBufObj.
