    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common parameter. The value used for this API: CreateLiveTranscodeTemplate.
    Version Yes String Common parameter. The value used for this API: 2018-08-01.
    Region No String Common parameter. This parameter is not required for this API.
    TemplateName Yes String Template name, such as “900p”. This can be only a combination of letters and digits.
    Length limit:

    origin: original codec as the output codec
    Description No String Template description.
    NeedVideo No Integer Whether to keep the video. 0: no; 1: yes. Default value: 1.
    Width No Integer Width. Default value: 0.

    It must be a multiple of 2. The original width is 0.
    NeedAudio No Integer Whether to keep the audio. 0: no; 1: yes. Default value: 1.
    Height No Integer Height. Default value: 0.
    Value range: [0,3000]
    The value must be a multiple of 2, and 0 is the original height.
    Fps No Integer Frame rate. Default value: 0.
    Value range: 0-60
    Gop No Integer Keyframe interval in seconds. Default value: original interval
    Value range: 2-6

    Valid values: 0, 90, 180, 270
    Profile No String Encoding quality:
    baseline/main/high. Default value: baseline.
    BitrateToOrig No Integer Whether to use the original bitrate when the set bitrate is larger than the original bitrate.
    0: no, 1: yes
    Default value: 0.
    HeightToOrig No Integer Whether to use the original height when the set height is higher than the original height.
    0: no, 1: yes
    Default value: 0.
    FpsToOrig No Integer Whether to use the original frame rate when the set frame rate is larger than the original frame rate.
    0: no, 1: yes
    Default value: 0.
    AiTransCode No Integer Whether it is a top speed codec template. 0: no, 1: yes. Default value: 0.
    AdaptBitratePercent No Float Bitrate compression ratio of top speed codec video.
    Target bitrate of top speed code = VideoBitrate * (1-AdaptBitratePercent)

    Value range: 0.0-0.5.
    ShortEdgeAsHeight No Integer Whether to use the short side as the video height. 0: no, 1: yes. Default value: 0.

    3. Output Parameters
