Fields

appId

Declaration

public UInt32 appId

Field Value

Type	Description
UInt32

audioBitrate

Description: bitrate (Kbps) of transcoded audio Value: default value: 64. Value range: [32,192]

Declaration

public UInt32 audioBitrate

Field Value

Type	Description
UInt32

audioChannels

Description: number of sound channels of transcoded audio Value: Valid values: 1 (default), 2

Declaration

public UInt32 audioChannels

Field Value

Type	Description
UInt32

audioSampleRate

Description: sample rate (Hz) of transcoded audio Value: Valid values: 12000, 16000, 22050, 24000, 32000, 44100, 48000 (default)

Declaration

public UInt32 audioSampleRate

Field Value

Type	Description
UInt32

backgroundColor

Description: background color of the mixing result. The default color is black, and the value is a hex number. For example: 0x61B9F1 represents the RGB color (97,158,241). Value: default value: 0x000000 (black)

Declaration

public UInt32 backgroundColor

Field Value

Type	Description
UInt32

backgroundImage

Description: background image of the mixing result Value: default value: null, which means that no background images are set Note: you need to first upload the image in Application Management > Function Configuration > Material Management in the console. You will get an image ID for the image uploaded, which you need to convert to a string before using it as the value of backgroundImage. For example, if the image ID is 63, you should set backgroundImage to 63.

Declaration

public string backgroundImage

Field Value

Type	Description
System.String

bizId

Description: Tencent Cloud bizid Value: In the TRTC console, find the application created, and click Application Info to view the bizid in the Relayed Live Streaming Info section.

Declaration

public UInt32 bizId

Field Value

Type	Description
UInt32

mixUsersArray

Description: position of each image

Declaration

public TRTCMixUser[] mixUsersArray

Field Value

Type	Description
TRTCMixUser[]

mixUsersArraySize

Description: number of elements in mixUsersArray

Declaration

public UInt32 mixUsersArraySize

Field Value

Type	Description
UInt32

mode

Description: On-Cloud MixTranscoding configuration mode

Declaration

public TRTCTranscodingConfigMode mode

Field Value

Type	Description
TRTCTranscodingConfigMode

streamId

Description: ID of the live stream relayed to CDN If you do not set this parameter, the SDK will execute the default logic, that is, it will mix multiple streams in the room into the video stream of the API caller, i.e., A + B => A. If you set this parameter, the SDK will mix multiple streams in the room into a stream whose ID you specify, i.e., A + B => C. Value: default value: null, which indicates that multiple streams in the room are mixed into the video stream of the API caller

Declaration

public string streamId

Field Value

Type	Description
System.String

videoBitrate

Description: bitrate (Kbps) of transcoded video Value: If you set this parameter to 0, the backend will work out a bitrate based on videoWidth and videoHeight. You can refer to the comment for the enumerated value TRTCVideoResolution_640_480.

Declaration

public UInt32 videoBitrate

Field Value

Type	Description
UInt32

videoFramerate

Description: frame rate (fps) of transcoded video Value: default value: 15. Value range: (0,30]

Declaration

public UInt32 videoFramerate

Field Value

Type	Description
UInt32

videoGOP

Description: keyframe interval (GOP) of transcoded video in seconds Value: default value: 2. Value range: [1,8]

Declaration

public UInt32 videoGOP

Field Value

Type	Description
UInt32

videoHeight

Description: height (px) of transcoded video Value: recommended value: 640. If audio-only streams are mixed, the mixing result will carry a video stream that shows a canvas background. To avoid this, set both the width and height to 0 px.

Declaration

public UInt32 videoHeight

Field Value

Type	Description
UInt32

videoWidth

Description: width (px) of transcoded video Value: recommended value: 360. If audio-only streams are mixed, the mixing result will carry a video stream that shows a canvas background. To avoid this, set both the width and height to 0 px.

Declaration

public UInt32 videoWidth

Field Value

Type	Description
UInt32
