Constructs a LiveTranscoding

Properties

audioBitrate ↔ int?

Bitrate (Kbps) of the CDN live audio output stream. The default value is 48 and the highest value is 128.

getter/setter pair

audioChannels ↔ AudioChannel?

Meta’s self-defined audio channel type. Meta recommends choosing 1 (mono), or 2 (stereo) audio channels. Special players are required if you choose 3, 4, or 5. See AudioChannel.

getter/setter pair

audioCodecProfile ↔ AudioCodecProfileType?

Audio codec profile type: AudioCodecProfileType. Set it as LCAAC or HEAAC. The default value is LCAAC.

getter/setter pair

audioSampleRate ↔ AudioSampleRateType?

Self-defined audio-sample rate: AudioSampleRateType.

getter/setter pair

backgroundColor ↔ Color?

The background color in RGB hex. Value only. Do not include a preceding #. For example, 0xFFB6C1 (light pink). The default value is 0x000000 (black). See Color.

getter/setter pair

backgroundImage ↔ MetaImage?

The background image added to the CDN live publishing stream. Once a background image is added, the audience of the CDN live publishing stream can see it. See MetaImage.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

height ↔ int?

Height (pixel) of the video. The default value is 640.

getter/setter pair

lowLatency ↔ bool?

Meta does not recommend using this parameter.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

transcodingUsers ↔ List<TranscodingUser>

An TranscodingUser object managing the user layout configuration in the CDN live stream. Meta supports a maximum of 17 transcoding users in a CDN live stream channel.

getter/setter pair

userConfigExtraInfo ↔ String?

Reserved property. Extra user-defined information to send the Supplemental Enhancement Information (SEI) for the H.264/H.265 video stream to the CDN live client. Maximum length: 4096 Bytes.

getter/setter pair

videoBitrate ↔ int?

Bitrate (Kbps) of the CDN live output video stream. The default value is 400. Set this parameter according to the VideoEncoderConfiguration.bitrate(Video Bitrate Table). If you set a bitrate beyond the proper range, the SDK automatically adapts it to a value within the range.

getter/setter pair

videoCodecProfile ↔ VideoCodecProfileType?

Video codec profile type: VideoCodecProfileType. Set it as BASELINE, MAIN, or HIGH (default). If you set this parameter to other values, Meta adjusts it to the default value HIGH.

getter/setter pair

videoFramerate ↔ VideoFrameRate?

The frame rate (fps) of the video. The value range is 0, 30. The default value is 15. The Meta server adjusts any value over 30 to 30.

getter/setter pair

videoGop ↔ int?

Gop of the video frames in the CDN live stream. The default value is 30 fps.

getter/setter pair

watermark ↔ MetaImage?

The watermark image added to the CDN live publishing stream. Ensure that the format of the image is PNG. Once a watermark image is added, the audience of the CDN live publishing stream can see it. See MetaImage.

getter/setter pair

width ↔ int?

Width (pixel) of the video. The default value is 360.

getter/setter pair

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

Operators

operator ==(Object other) → bool

The equality operator.
