ILMAV1Encoder

This is the interface for the LEAD AV1 Encoder.

Data Types

eAV1ControlMode

Summary

Indicates which encoding mode should be used.

Syntax

typedef enum 
{ 
   AV1ControlMode_CBR_Driven = 0, 
   AV1ControlMode_Quality_Driven	= ( AV1ControlMode_CBR_Driven + 1 ) 
} eAV1ControlMode; 

Members

AV1ControlMode_CBR_Driven

Encodes using constant bit rate (CBR) mode.

AV1ControlMode_Quality_Driven

Encodes using variable bit rate (VBR) to match a specified quality level.

eAV1EncApiLevel

Summary

Lists the valid values for the ApiLevel parameter that can be passed to the ResetToDefaultsEx method.

Syntax

typedef enum 
{ 
   LAV1Enc_ApiLevel_1 = 0,    // current version 
} eAV1EncApiLevel; 

Properties

Methods

HRESULT ResetToDefaultsEx(eAV1EncApiLevel ApiLevel)

Description

Resets the filter to default values.

Parameters

ApiLevel

Specifies which defaults should be used by the encoder. Current applications should set ApiLevel to LAV1Enc_ApiLevel_1 = 0.

Comments

The encoder might change in the future and have different properties or default behavior. Calling this method ensures future versions of the filter will behave the same way as when you developed your application.

It is best to call ResetToDefaultsEx(LAV1Enc_ApiLevel_1) before you start setting properties and start calling other methods for this interface.
