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