Detailed Description
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.

Typedef Documentation
◆ VdpDecoder
| typedef uint32_t VdpDecoder |
An opaque handle representing a VdpDecoder object.
◆ VdpDecoderCreate
| typedef VdpStatus VdpDecoderCreate(VdpDevice device, VdpDecoderProfile profile, uint32_t width, uint32_t height, uint32_t max_references, VdpDecoder *decoder) |
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.
◆ VdpDecoderDestroy
| typedef VdpStatus VdpDecoderDestroy(VdpDecoder decoder) |
Destroy a VdpDecoder.
- Parameters
-
[in] surface The decoder's handle.
- Returns
- VdpStatus The completion status of the operation.
◆ VdpDecoderGetParameters
| typedef VdpStatus VdpDecoderGetParameters(VdpDecoder decoder, VdpDecoderProfile *profile, uint32_t *width, uint32_t *height) |
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.
◆ VdpDecoderProfile
| typedef uint32_t VdpDecoderProfile |
The set of all known compressed video formats, and associated profiles, that may be decoded.
◆ VdpDecoderQueryCapabilities
| typedef VdpStatus VdpDecoderQueryCapabilities(VdpDevice device, VdpDecoderProfile profile, VdpBool *is_supported, uint32_t *max_level, uint32_t *max_macroblocks, uint32_t *max_width, uint32_t *max_height) |
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.
◆ VdpDecoderQueryProfileCapability
| typedef VdpStatus VdpDecoderQueryProfileCapability(VdpDevice device, VdpDecoderProfile profile, VdpDecoderCapability capability, void *capability_value) |
Query the supported value of the requested capability, for the specified profile on the specified device.
- Parameters
-
[in] device The device to query. [in] profile The decoder profile for which information is requested. [in] capability The decoder profile capability for which the value is requested. [out] capability_value The value of the requested capability.
- Returns
- VdpStatus The completion status of the operation.
◆ VdpDecoderRender
| typedef VdpStatus VdpDecoderRender(VdpDecoder decoder, VdpVideoSurface target, VdpPictureInfo const *picture_info, uint32_t bitstream_buffer_count, VdpBitstreamBuffer const *bitstream_buffers) |
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.
See Video Mixer Usage for additional information.
◆ VdpPictureInfo
| typedef void VdpPictureInfo |
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.
◆ VdpPictureInfoDivX4
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.
◆ VdpPictureInfoDivX5
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.
◆ VdpPictureInfoHEVCRangeExt
Picture parameter information for HEVC FormatRangeExtensions picture.
HEVC Main 444 Profile is part of Format Range Extensions profiles, Due to similarities between Format Range Extensions profiles, the picture parameter structure is re-used for Format Range Extensions profiles supported.
