Detailed Description
This is the VIDDEC video decoder interface. Several of the data types in this API are specified by the XDM interface; please see the XDM documentation for those details.

Typedef Documentation
Defines instance status parameters.
@remarks This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the @c size parameter.
Opaque handle to a VIDDEC codec.
This structure defines the parameters necessary to create an instance of a video decoder object.
Defines the input arguments for all IVIDDEC instance process function.
@remarks This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the @c size parameter.
Defines the run time output arguments for all IVIDDEC instance objects.
@remarks This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the @c size parameter.
This structure defines the codec parameters that can be modified after creation via control() calls.
@remarks It is not necessary that a given implementation support all
dynamic parameters to be configurable at run time. If a
particular algorithm does not support run-time updates to
a parameter that the application is attempting to change
at runtime, it may indicate this as an error.

Function Documentation
Create an instance of a video decoder algorithm.
Instance handles must not be concurrently accessed by multiple threads;
each thread must either obtain its own handle (via VIDDEC_create()) or
explicitly serialize access to a shared handle.
@param[in] e Handle to an opened engine.
@param[in] name String identifier of the type of video decoder.
to create.
@param[in] params Creation parameters.
@retval NULL An error has occurred.
@retval non-NULL The handle to the newly created video decoder
instance.
@remarks @c params is optional. If it's not supplied, codec-specific
default params will be used.
@remark Depending on the configuration of the engine opened, this
call may create a local or remote instance of the video
decoder.
@remarks In general, @c name is the name of the codec configured by the system integrator. However, an optional "argument string" may be appended to the codec name, to allow the codec's configured priority and/or the heaps where its memory will be allocated, to be overridden. This optional argument string is of the form <b>":priority"</b>, <b>":priority:flag"</b>, or <b>"::flag"</b>.
Execute the process() method in this instance of a video decoder algorithm.
