API¶

mfxExtColorConversion ¶

struct mfxExtColorConversion¶

A hint structure that tunes the VPP Color Conversion algorithm when attached to the mfxVideoParam structure during VPP Init.

Public Members

mfxExtBuffer Header¶: Extension buffer header. Header.BufferId must be equal to MFX_EXTBUFF_VPP_COLOR_CONVERSION.

mfxU16 ChromaSiting¶: See ChromaSiting enumerator for details.

ChromaSiting is applied on input or output surface depending on the scenario:

VPP Input	VPP Output	ChromaSiting Indicates
MFX_CHROMAFORMAT_YUV420 MFX_CHROMAFORMAT_YUV422	MFX_CHROMAFORMAT_YUV444	Chroma location for input
MFX_CHROMAFORMAT_YUV444	MFX_CHROMAFORMAT_YUV420 MFX_CHROMAFORMAT_YUV422	Chroma location for output
MFX_CHROMAFORMAT_YUV420	MFX_CHROMAFORMAT_YUV420	Chroma location for input and output
MFX_CHROMAFORMAT_YUV420	MFX_CHROMAFORMAT_YUV422	Horizontal location for input and output, vertical location for input

If attached to the mfxVideoParam structure during the Init stage, this buffer will instruct the decoder to resize output frames via the fixed function resize engine (if supported by hardware), utilizing direct pipe connection and bypassing intermediate memory operations. The main benefits of this mode of pipeline operation are offloading resize operation to a dedicated engine, thus reducing power consumption and memory traffic.

Public Members

mfxExtEncodedSlicesInfo ¶

struct mfxExtEncodedSlicesInfo¶

Used by the encoder to report additional information about encoded slices. The application can attach this buffer to the mfxBitstream structure before calling the MFXVideoENCODE_EncodeFrameAsync function.

Note

Not all implementations of the encoder support this extended buffer. The application must use query mode 1 to determine if the functionality is supported. To do this, the application must attach this extended buffer to the mfxVideoParam structure and call the MFXVideoENCODE_Query function. If the function returns MFX_ERR_NONE, then the functionality is supported.

Public Members

Public Members

mfxExtBuffer Header¶: Extension buffer header. Header.BufferId must be equal to MFX_EXTBUFF_VPP_COLORFILL.

mfxU16 Enable¶: Set to ON makes VPP fill the area between Width/Height and Crop borders. See the CodingOptionValue enumerator for values of this option.

mfxExtVPPComposite ¶

struct mfxExtVPPComposite¶

Used to control composition of several input surfaces in one output. In this mode, the VPP skips any other filters. The VPP returns an error if any mandatory filter is specified and returns the filter skipped warning if an optional filter is specified. The only supported filters are deinterlacing and interlaced scaling. The only supported combinations of input and output color formats are:

RGB to RGB,
NV12 to NV12,
RGB and NV12 to NV12, for per the pixel alpha blending use case.

The VPP returns MFX_ERR_MORE_DATA for additional input until an output is ready. When the output is ready, the VPP returns MFX_ERR_NONE. The application must process the output frame after synchronization.

The composition process is controlled by:

mfxFrameInfo::CropXYWH in the input surface defines the location of the picture in the input frame.
InputStream[i].DstXYWH defines the location of the cropped input picture in the output frame.
mfxFrameInfo::CropXYWH in the output surface defines the actual part of the output frame. All pixels in the output frame outside this region will be filled by the specified color.

If the application uses the composition process on video streams with different frame sizes, the application should provide maximum frame size in the mfxVideoParam structure during the initialization, reset, or query operations.

If the application uses the composition process, the MFXVideoVPP_QueryIOSurf function returns the cumulative number of input surfaces, that is, the number required to process all input video streams. The function sets the frame size in the mfxFrameAllocRequest equal to the size provided by the application in the mfxVideoParam structure.

The composition process supports all types of surfaces.

All input surfaces should have the same type and color format, except for the per pixel alpha blending case, where it is allowable to mix NV12 and RGB surfaces.

There are three different blending use cases:

Luma keying. All input surfaces should have the NV12 color format specified during VPP initialization. Part of each surface, including the first one, may be rendered transparent by using LumaKeyEnable, LumaKeyMin, and LumaKeyMax values.
Global alpha blending. All input surfaces should have the same color format, NV12 or RGB, specified during VPP initialization. Each input surface, including the first one, can be blended with underlying surfaces by using GlobalAlphaEnable and GlobalAlpha values.
Per-pixel alpha blending. It is allowed to mix NV12 and RGB input surfaces. Each RGB input surface, including the first one, can be blended with underlying surfaces by using PixelAlphaEnable value.

It is not allowed to mix different blending use cases in the same function call.

In the special case where the destination region of the output surface defined by output crops is fully covered with destination sub-regions of the surfaces, the fast compositing mode can be enabled. The main use case for this mode is a video-wall scenario with a fixed destination surface partition into sub-regions of potentially different size.

In order to trigger this mode, the application must cluster input surfaces into tiles, defining at least one tile by setting the NumTiles field to be greater than 0, and assigning surfaces to the corresponding tiles by setting the TileId field to the value within the 0 to NumTiles range per input surface. Tiles should also satisfy the following additional constraints:

Each tile should not have more than 8 surfaces assigned to it.
Tile bounding boxes, as defined by the enclosing rectangles of a union of a surfaces assigned to this tile, should not intersect.

Background color may be changed dynamically through Reset. There is no default value. YUV black is (0;128;128) or (16;128;128) depending on the sample range. The library uses a YUV or RGB triple depending on output color format.

Tells the VPP to include certain filters in the pipeline.

Each filter may be included in the pipeline in one of two different ways:

Adding a filter ID to this structure. In this method, the default filter parameters are used.

Attaching a filter configuration structure directly to the mfxVideoParam structure. In this method, adding filter ID to the mfxExtVPPDoUse structure is optional.

See Table “Configurable VPP filters” for complete list of configurable filters, their IDs, and configuration structures.

The user can attach this structure to the mfxVideoParam structure when initializing video processing.

Note

MFX_EXTBUFF_VPP_COMPOSITE cannot be enabled using mfxExtVPPDoUse because default parameters are undefined for this filter. The application must attach the appropriate filter configuration structure directly to the mfxVideoParam structure to enable it.

Public Members

Runtime configuration has priority over initialization configuration. If the field processing algorithm was activated via the mfxExtVPPDoUse structure and the mfxExtVPPFieldProcessing extended buffer was not provided during initialization, this buffer must be attached to the mfxFrameData structure of each input surface.

Public Members

mfxExtBuffer Header¶: Extension buffer header. Header.BufferId must be equal to MFX_EXTBUFF_VPP_FIELD_PROCESSING.

mfxU16 Mode¶: Specifies the mode of the field processing algorithm. See the VPPFieldProcessingMode enumerator for values of this option.

mfxU16 OutField¶: When Mode is MFX_VPP_COPY_FIELD, specifies output field. See the PicType enumerator for values of this parameter.

mfxExtVPPFrameRateConversion ¶

struct mfxExtVPPFrameRateConversion¶

Configures the VPP frame rate conversion filter. The user can attach this structure to the mfxVideoParam structure when initializing, resetting, or querying capability of video processing.

On some platforms the advanced frame rate conversion algorithm (the algorithm based on frame interpolation) is not supported. To query its support, the application should add the MFX_FRCALGM_FRAME_INTERPOLATION flag to the Algorithm value in the mfxExtVPPFrameRateConversion structure, attach it to the structure, and call the MFXVideoVPP_Query function. If the filter is supported, the function returns a MFX_ERR_NONE status and copies the content of the input structure to the output structure. If an advanced filter is not supported, then a simple filter will be used and the function returns MFX_WRN_INCOMPATIBLE_VIDEO_PARAM, copies content of the input structure to the output structure, and corrects the Algorithm value.

If advanced FRC algorithm is not supported, both MFXVideoVPP_Init and MFXVideoVPP_Reset functions return the MFX_WRN_INCOMPATIBLE_VIDEO_PARAM status.

Public Members

mfxExtBuffer Header¶: Extension buffer header. Header.BufferId must be equal to MFX_EXTBUFF_VPP_FRAME_RATE_CONVERSION.

mfxU16 Algorithm¶: See the FrcAlgm enumerator for a list of frame rate conversion algorithms.

mfxExtVPPImageStab ¶

struct mfxExtVPPImageStab¶

A hint structure that configures the VPP image stabilization filter.

On some platforms this filter is not supported. To query its support, the application should use the same approach that it uses to configure VPP filters: adding the filter ID to the mfxExtVPPDoUse structure or by attaching the mfxExtVPPImageStab structure directly to the mfxVideoParam structure and calling the MFXVideoVPP_Query function.

If this filter is supported, the function returns a MFX_ERR_NONE status and copies the content of the input structure to the output structure. If the filter is not supported, the function returns MFX_WRN_FILTER_SKIPPED, removes the filter from the mfxExtVPPDoUse structure, and zeroes the mfxExtVPPImageStab structure.

If the image stabilization filter is not supported, both MFXVideoVPP_Init and MFXVideoVPP_Reset functions return a MFX_WRN_FILTER_SKIPPED status.

The application can retrieve the list of active filters by attaching the mfxExtVPPDoUse structure to the mfxVideoParam structure and calling the MFXVideoVPP_GetVideoParam function. The application must allocate enough memory for the filter list.

Public Members

mfxExtBuffer Header¶: Extension buffer header. Header.BufferId must be equal to MFX_EXTBUFF_VPP_MCTF.

mfxU16 FilterStrength¶

Value in range of 0 to 20 (inclusive) to indicate the filter strength of MCTF.

The strength of the MCTF process controls the degree of possible change of pixel values eligible for MCTF - the greater the strength value, the larger the change. It is a dimensionless quantity - values in the range of 1 to 20 inclusively imply strength; value 0 stands for AUTO mode and is valid during initialization or reset only

If an invalid value is given, it is fixed to the default value of 0. If the field value is in the range of 1 to 20 inclusive, MCTF operates in fixed-strength mode with the given strength of MCTF process.

At runtime, values of 0 and greater than 20 are ignored.
