Typedef Documentation
Opaque handle to a AUDDEC codec.
Defines the creation time parameters for all IAUDDEC instance objects.
This structure defines the codec parameters that can be modified after creation via control() calls.

Function Documentation
Execute the control() method in this instance of an audio decoder algorithm.
- Parameters:
-
[in] | handle | Handle to a created audio decoder instance. |
[in] | id | Command id for XDM control operation. |
[in] | params | Runtime control parameters used for decoding. |
[out] | status | Status info upon completion of decode operation. |
- Precondition:
handle
is a valid (non-NULL) audio decoder handle and the audio decoder is in the created state.
- Return values:
-
- See also:
- AUDDEC_create()
-
AUDDEC_delete()
-
IAUDDEC_Fxns::control()
Create an instance of a audio decoder algorithm.
Instance handles must not be concurrently accessed by multiple threads; each thread must either obtain its own handle (via AUDDEC_create()) or explicitly serialize access to a shared handle.
- Parameters:
-
[in] | e | Handle to an opened engine. |
[in] | name | String identifier of the type of audio decoder. to create. |
[in] | params | Creation parameters. |
- Return values:
-
NULL | An error has occurred. |
non-NULL | The handle to the newly created audio decoder instance. |
- See also:
- Engine_open()
-
AUDDEC_delete()
Delete the instance of an audio decoder algorithm.
- Parameters:
-
[in] | handle | Handle to a created audio decoder instance. |
- Precondition:
handle
is a valid (non-NULL) handle which is in the created state.
- Postcondition:
- All resources allocated as part of the AUDDEC_create() operation (memory, DMA channels, etc.) are freed.
- See also:
- AUDDEC_create()
Execute the process() method in this instance of an audio decoder algorithm.
- Parameters:
-
[in] | handle | Handle to a created audio decoder instance. |
[in] | inBufs | A buffer descriptor containing input buffers. |
[out] | outBufs | A buffer descriptor containing output buffers. |
[in] | inArgs | Input Arguments. |
[out] | outArgs | Output Arguments. |
- Precondition:
handle
is a valid (non-NULL) audio decoder handle and the audio decoder is in the created state.
- Return values:

-
IAUDDEC_Fxns::process() - the reflected algorithm interface, which may contain further usage details.
