IWMEncAudienceObj::get_VideoImageSharpness
The get_VideoImageSharpness method retrieves a value indicating the video image quality.
Syntax
HRESULT get_VideoImageSharpness(
short iRenderSiteIndex,
long* plIQuality
);
Parameters
iRenderSiteIndex
[in] short containing the audience stream index. Because an audience can only contain one stream of each type, iRenderSiteIndex must be zero.
plIQuality
[out] Pointer to a long between 0 to 100 indicating the quality of the video image.
Return Values
If the method succeeds, it returns S_OK. If it fails, it supports the IErrorInfo interface and returns an HRESULT error code.
Return code | Number | Description |
E_POINTER | 0x80004003 | The pointer to the video image quality is NULL. |
Remarks
The get_VideoImageSharpness method is used for constant bit rate (CBR) mode. A lower value results in smoother image movement and a higher frame rate, while a higher value results in a clearer image and a decrease in frame rate.
