The VdpDecoder object decodes compressed video data, writing the results to a VdpVideoSurface.
A specific VDPAU implementation may support decoding multiple types of compressed video data. However, VdpDecoder objects are able to decode a specific type of compressed video data. This type must be specified during creation.

An opaque handle representing a VdpDecoder object.
Create a VdpDecoder.
- Parameters
-
| [in] | device | The device that will contain the surface. |
| [in] | profile | The video format the decoder will decode. |
| [in] | width | The width of the new surface. |
| [in] | height | The height of the new surface. |
| [in] | max_references | The maximum number of references that may be used by a single frame in the stream to be decoded. This parameter exists mainly for formats such as H.264, where different streams may use a different number of references. Requesting too many references may waste memory, but decoding should still operate correctly. Requesting too few references will cause decoding to fail. |
| [out] | decoder | The new decoder's handle. |
- Returns
- VdpStatus The completion status of the operation.
Destroy a VdpDecoder.
- Parameters
-
| [in] | surface | The decoder's handle. |
- Returns
- VdpStatus The completion status of the operation.
Retrieve the parameters used to create a VdpDecoder.
- Parameters
-
| [in] | surface | The surface's handle. |
| [out] | profile | The video format used to create the decoder. |
| [out] | width | The width of surfaces decode by the decoder. |
| [out] | height | The height of surfaces decode by the decoder |
- Returns
- VdpStatus The completion status of the operation.
The set of all known compressed video formats, and associated profiles, that may be decoded.
Query the implementation's VdpDecoder capabilities.
- Parameters
-
| [in] | device | The device to query. |
| [in] | profile | The decoder profile for which information is requested. |
| [out] | is_supported | Is this profile supported? |
| [out] | max_level | The maximum specification level supported for this profile. |
| [out] | max_macroblocks | The maximum supported surface size in macroblocks. Note that this could be greater than that dictated by the maximum level. |
| [out] | max_width | The maximum supported surface width for this profile. Note that this could be greater than that dictated by the maximum level. |
| [out] | max_height | The maximum supported surface height for this profile. Note that this could be greater than that dictated by the maximum level. |
- Returns
- VdpStatus The completion status of the operation.
Decode a compressed field/frame and render the result into a VdpVideoSurface.
- Parameters
-
| [in] | decoder | The decoder object that will perform the decode operation. |
| [in] | target | The video surface to render to. |
| [in] | picture_info | A (pointer to a) structure containing information about the picture to be decoded. Note that the appropriate type of VdpPictureInfo* structure must be provided to match to profile that the decoder was created for. |
| [in] | bitstream_buffer_count | The number of bitstream buffers containing compressed data for this picture. |
| [in] | bitstream_buffers | An array of bitstream buffers. |
- Returns
- VdpStatus The completion status of the operation.

A generic "picture information" 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" VdpPictureInfo* structures, picking the type appropriate for the decoder object in question.
Picture parameter information for a DivX 4 picture.
Due to similarites between MPEG-4 Part 2 and DivX 4, the picture parameter structure is re-used.
Picture parameter information for a DivX 5 picture.
Due to similarites between MPEG-4 Part 2 and DivX 5, the picture parameter structure is re-used.
