The following attributes are supported by the LEAD Video Stabilizer Transform through the IMFAttributes interface.

Interface Properties

Data type

Attribute CLSID

Description

UINT32 (BOOL)

LMF_VSTABILIZE_ENABLED

Enables or disables video stabilization. If set to FALSE, the transform passes the video samples intact.

UINT32 (BOOL)

LMF_VSTABILIZE_AUTORECONNECT

If set to TRUE, the transform can apply changes that affect media types while the media session is running (without having to stop and manually reconnect).This includes options such as clipping.

UINT32 (BOOL)

LMF_VSTABILIZE_ROIENABLED

If set to TRUE, the transform processes only the region of interest. Otherwise, the entire frame gets processed.

The region of interest restricts the area considered when reducing shaking, but the reductions are applied to the entire frame. Limiting the transform to a portion of the video increases performance, allowing the transform to be run in real time.

UINT32 (long)

LMF_VSTABILIZE_ROITOP

Top coordinate, in pixels, of the region of interest

UINT32 (long)

LMF_VSTABILIZE_ROILEFT

Left coordinate, in pixels, of the region of interest

UINT32 (long)

LMF_VSTABILIZE_ROIBOTTOM

Bottom coordinate, in pixels, of the region of interest

UINT32 (long)

LMF_VSTABILIZE_ROIRIGHT

Right coordinate, in pixels, of the region of interest

UINT32 (lmvstab_GlobalEstimationCoefficients)

LMF_VSTABILIZE_GLOBALESTIMATIONCOEFFICIENTS

Gets or sets the lmvstab_GlobalEstimationCoefficients value to be used. This describes the type of stabilization to be performed.

UINT32 (lmvstab_GlobalEstimationQuality)

LMF_VSTABILIZE_GLOBALESTIMATIONQUALITY

Gets or sets the lmvstab_GlobalEstimationQuality value to be used. This value describes the balance between the speed and the quality of the processing.

UINT32 (lmvstab_PathSmoothingLevel)

LMF_VSTABILIZE_PATHSMOOTHINGLEVEL

Gets or sets the lmvstab_PathSmoothingLevel values to be used.

UINT32 (OLE_COLOR)

LMF_VSTABILIZE_BACKGROUNDFILLCOLOR

Color to use to fill any empty areas resulting from processing.

UINT32 (BOOL)

 

If set to TRUE, the transform will apply cropping on the frames. Otherwise, the frame processed normally.

UINT32 (long)

LMF_VSTABILIZE_LEFTRIGHTCROPMARGIN

Left and right crop margin

UINT32 (long)

LMF_VSTABILIZE_TOPBOTTOMCROPMARGIN

Top and bottom crop margin

UINT32 (lmvstab_InterpolationType)

LMF_VSTABILIZE_INTERPOLATIONTYPE

Gets and sets the lmvstab_InterpolationType value to be used.

UINT32 (lmvstab_enumClippingOption)

LMF_VSTABILIZE_CLIPPINGOPTION

Gets and sets the lmvstab_enumClippingOption value to be used.
