如何直接调用虚拟演播厅OpenAPI的Demo_视频直播(LIVE)-阿里云帮助中心

本文提供了直接调用虚拟演播厅OpenAPI的Demo，具体逻辑请根据实际情况自行编写。

虚拟演播厅调用流程

虚拟演播厅整个调用流程顺序如下：

重要

请先添加视频资源再添加布局，否则布局无法生效。

创建导播台
设置导播台
添加视频资源
添加虚拟演播厅布局
启动导播台
更新导播台场景配置
停止导播台
删除虚拟演播厅布局

示例代码

说明

了解API的详细信息，请参见云导播API概览。
使用Go SDK，具体请参见Go SDK使用说明。

创建导播台

// 创建导播台
func CreateCaster(liveClient *live20161101.Client) (*live20161101.CreateCasterResponse, error) {
	// 创建导播台请求参数
	createCasterRequest := &live20161101.CreateCasterRequest{}
	createCasterRequest.ClientToken = tea.String(uuid.New().String())
	createCasterRequest.CasterName = tea.String("导播台测试")
	createCasterRequest.ChargeType = tea.String("PostPaid")
	createCasterRequest.NormType = tea.Int32(1)
	createCasterResponse, err := liveClient.CreateCaster(createCasterRequest)
	if err != nil {
		return nil, errors.New("CreateCaster failed: " + err.Error())
	}
	return createCasterResponse, nil
}

关于CreateCaster接口的请求参数等更多信息，请参见创建导播台。

设置导播台

// 设置导播台
func SetCasterConfig(liveClient *live20161101.Client, casterId *string, domainName *string) (*live20161101.SetCasterConfigResponse, error) {
	// 设置导播台配置参数
	createSetCasterConfig := &live20161101.SetCasterConfigRequest{}
	createSetCasterConfig.CasterId = casterId
	createSetCasterConfig.CasterName = tea.String("导播台测试")
	createSetCasterConfig.ChannelEnable = tea.Int32(1)
	createSetCasterConfig.Delay = tea.Float32(0)
	createSetCasterConfig.DomainName = domainName
	createSetCasterConfig.ProgramEffect = tea.Int32(1)
	createSetCasterConfig.ProgramName = tea.String("test loop play")
	// 转码设置（横竖屏模式及清晰度设置）
	// 其中：CasterTemplate取值范围如下：lp_ld：流畅、lp_sd：标清、lp_hd：高清、lp_ud：超清。lp_ld_v：竖屏流畅、lp_sd_v：竖屏标清、lp_hd_v：竖屏高清、lp_ud_v：竖屏超清。
	createSetCasterConfig.TranscodeConfig = tea.String(`{"CasterTemplate": "lp_ld"}`)
	// 配置导播台直播录制参数。json字段含义请参考：AddLiveAppRecordConfig
	// createSetCasterConfig.RecordConfig = tea.String(`{ "endpoint": "", "ossBucket": "", "videoFormat": [{"format": "flv", "interval": 900, "prefix":"record/{AppName}/{StreamName}/{StartTime}_{EndTime}" }]}`)
	setCasterConfigResponse, err := liveClient.SetCasterConfig(createSetCasterConfig)
	if err != nil {
		return nil, errors.New("SetCasterConfig failed: " + err.Error())
	}
	return setCasterConfigResponse, nil
}
