Attributes
- dimensions
-
The dimensions of the encoded video (px). See VideoDimensions. This parameter measures the video encoding quality in the format of length × width. The default value is 960 × 540. You can set a custom value.
- codecType
- The codec type of the local video stream. See VideoCodecType.
- frameRate
- The frame rate (fps) of the encoding video frame. The default value is 15. See FrameRate.
- bitrate
-
The encoding bitrate (Kbps) of the video. This parameter does not need to be set; keeping the default value STANDARD_BITRATE is sufficient. The SDK automatically matches the most suitable bitrate based on the video resolution and frame rate you have set. For the correspondence between video resolution and frame rate, see Video profile.
- STANDARD_BITRATE(0): (Recommended) Standard bitrate mode.
- COMPATIBLE_BITRATE(-1): Adaptive bitrate mode. In general, Agora suggests that you do not use this value.
- minBitrate
-
The minimum encoding bitrate (Kbps) of the video.
The SDK automatically adjusts the encoding bitrate to adapt to the network conditions. Using a value greater than the default value forces the video encoder to output high-quality images but may cause more packet loss and sacrifice the smoothness of the video transmission. Unless you have special requirements for image quality, Agora does not recommend changing this value.
Attention: This parameter only applies to the interactive streaming profile. - orientationMode
- The orientation mode of the encoded video. See OrientationMode.
- degradationPreference
- Video degradation preference under limited bandwidth. See DegradationPreference.Attention: When this parameter is set to MaintainFramerate (1) or MaintainBalanced (2), orientationMode needs to be set to OrientationModeAdaptive (0) at the same time, otherwise the setting will not take effect.
- mirrorMode
-
Sets the mirror mode of the published local video stream. It only affects the video that the remote user sees. See VideoMirrorModeType.
Attention: By default, the video is not mirrored. - advanceOptions
- Advanced options for video encoding. See AdvanceOptions.
