A complete, runnable demo for managing a virtual studio by calling ApsaraVideo Live API operations.

API workflow

Sample code

Note

  • Create a production studio

    // Create a production studio.
func CreateCaster(liveClient *live20161101.Client) (*live20161101.CreateCasterResponse, error) {
	// The request parameters for creating a production studio.

	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())
	}

}

    For request parameters, see CreateCaster.

  • Configure the production studio

    // Configure the production studio.

	createSetCasterConfig.DomainName = domainName
	createSetCasterConfig.ProgramEffect = tea.Int32(1)
	createSetCasterConfig.ProgramName = tea.String("test loop play")
	// Transcoding settings (screen orientation and definition).
	// The CasterTemplate parameter can be set to the following values: lp_ld (low definition), lp_sd (standard definition), lp_hd (high definition), or lp_ud (ultra-high definition). lp_ld_v (low definition in portrait mode), lp_sd_v (standard definition in portrait mode), lp_hd_v (high definition in portrait mode), or lp_ud_v (ultra-high definition in portrait mode).
	createSetCasterConfig.TranscodeConfig = tea.String(`{"CasterTemplate": "lp_ld"}`)
	// Configure the recording parameters for the production studio. For more information about the JSON fields, see 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 {
