## Detailed Description

The IVideoBeautyFilter class.

## Member Function Documentation

## ◆ setEnabled()

virtual void setEnabled | ( | bool | enable | ) |
| inline virtual inherited

Enables or disables the video filter.

Parameters

  enable | Whether to enable the video filter: `true`: (Default) Enable the video filter. `false`: Do not enable the video filter. If the filter is disabled, frames will be passed without adaption.

## ◆ isEnabled()

virtual bool isEnabled | ( |  | ) |
| inline virtual inherited

Checks whether the video filter is enabled.

Returns
  - `true`: The video filter is enabled.
  - `false`: The video filter is not enabled.

## ◆ setProperty()

virtual int setProperty | ( | const char * | key,
|  | const void * | buf,
|  | size_t | buf_size
| ) |  |
| inline virtual inherited

Sets a private property in the `IVideoFilter` class.

Parameters

  key | The pointer to the property name.
  buf | The pointer to the buffer of this private property.
  buf_size | The buffer size of this private property.

Returns
  - The actual size of the private property, if the method call succeeds.
  - -1, if the method call fails.

## ◆ getProperty()

virtual int getProperty | ( | const char * | key,
|  | void * | buf,
|  | size_t | buf_size
| ) |  |
| inline virtual inherited

Gets a private property in the IVideoFilter class.

Parameters

  key | The pointer to the property name.
  buf | The pointer to the buffer of this private property.
  buf_size | The buffer size of this private property.

Returns
  - The actual size of the private property, if the method call succeeds.
  - -1, if the method call fails.

## ◆ onDataStreamWillStart()

virtual bool onDataStreamWillStart | ( |  | ) |
| inline virtual inherited

This function is invoked right before data stream starts. Custom filter can override this function for initialization.

Returns
  - `true`: The initialization succeeds.
  - `false`: The initialization fails.

## ◆ onDataStreamWillStop()

virtual void onDataStreamWillStop | ( |  | ) |
| inline virtual inherited

This function is invoked right before data stream stops. Custom filter can override this function for deinitialization.

## ◆ isExternal()

virtual bool isExternal | ( |  | ) |
| inline virtual inherited

This function indicates if the filter is for internal use.

Note
  Do not override this function.

Returns
  - `true`: The filter is implemented by external users.
  - `false`: The filter is implemented by internal users.

## ◆ isExtensionFilter()

virtual bool isExtensionFilter | ( |  | ) |
| inline virtual inherited

This function indicates if the filter is implemented by third-party providers.

Note
  Do not override this function.

Returns
  - `true`: The filter is implemented by third-party providers.
  - `false`: otherwise.

Reimplemented in IExtensionVideoFilter.

## ◆ adaptVideoFrame()

virtual bool adaptVideoFrame | ( | const media::base::VideoFrame & | capturedFrame,
|  | media::base::VideoFrame & | adaptedFrame
| ) |  |
| pure virtual inherited

Adapts the video frame.

Parameters

  capturedFrame | The reference to the captured video frame that you want to adapt.
  adaptedFrame | The reference to the adapted video frame.

Returns
  - `true`: Success.
  - `false`: Failure, if, for example, the `IVideofilter` object drops the video frame.

Implemented in IExtensionVideoFilter.

## ◆ AddRef()

virtual void AddRef | ( |  | ) | const
| pure virtual inherited

## ◆ Release()

virtual RefCountReleaseStatus Release | ( |  | ) | const
| pure virtual inherited

## ◆ HasOneRef()

virtual bool HasOneRef | ( |  | ) | const
| pure virtual inherited
