Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. This parameter is mandatory when token authentication is used. It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token.
Access-Control-Allow-Internal	No	String	Service authentication token. If authentication is enabled for a service, Access-Control-Allow-Internal must be carried to access the service.
Access-Control-Allow-External	No	String	Service authentication token. If authentication is enabled for a service, Access-Control-Allow-External must be carried to access the service.

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
domain	Yes	String	Ingest domain name of a channel.
app_name	Yes	String	Group name or application name.
id	Yes	String	Unique ID of a channel. This parameter is mandatory.
input	No	InputStreamInfo object	Channel output stream information.

**Table 4** InputStreamInfo
Parameter	Mandatory	Type	Description
input_protocol	Yes	String	Channel input protocol FLV_PULL RTMP_PUSH HLS_PULL SRT_PULL SRT_PUSH
sources	No	Array of SourcesInfo objects	Information about the primary source stream of a channel. This parameter is optional when the stream input protocol is RTMP_PUSH or SRT_PUSH. In other cases, this parameter is mandatory.
secondary_sources	No	Array of SecondarySourcesInfo objects	Standby input stream array. This parameter is optional. If there is a standby input stream, ensure that the number of channels, codec, and resolution of the primary and standby input streams are the same. If the stream input protocol is RTMP_PUSH, you do not need to specify this parameter.
failover_conditions	No	FailoverConditions object	(Optional) Configuration provided by the channel supplier to switch between the primary and standby media stream URLs.
max_bandwidth_limit	No	Integer	Maximum bandwidth required when the input protocol is HLS_PULL. A streaming URL provided by the user includes the parameter BANDWIDTH for audios/videos with different bitrates. If the maximum bandwidth is specified, Media Live will pull the media stream that has the highest bitrate and a bandwidth lower than the maximum bandwidth from the URL, and push the stream to the origin server. If the maximum bandwidth is not specified, Media Live will pull the media stream with the largest BANDWIDTH value from the URL, and push the stream to the origin server.
ip_port_mode	No	Boolean	When the stream push protocol is SRT_PUSH and streams are pushed to the origin server, the encoder does not support the input of streamid. In this case, set this parameter to true.
ip_whitelist	No	String	IP address whitelist of the customer for SRT_PUSH
scte35_source	No	String	SCTE-35 signal source of an advertisement. Only HLS_PULL channels support this configuration. Currently, this field can only be set to SEGMENTS.
ad_triggers	No	Array of strings	Configures an ad trigger. Options: Splice insert Provider advertisement Distributor advertisement Provider placement opportunity Distributor placement opportunity
audio_selectors	No	Array of InputAudioSelector objects	Configures an audio selector (a maximum of 8).

**Table 5** SourcesInfo
Parameter	Mandatory	Type	Description
url	No	String	Channel source stream URL, which is used for external stream pull.

width	No	Integer	Width corresponding to the resolution. This parameter is optional. Value range: 0–4096 (4K)
height	No	Integer	Height corresponding to the resolution. This parameter is optional. Value range: 0–2160 (4K)
enable_snapshot	No	Boolean	Whether to use the stream for snapshot capturing.

passphrase	No	String	Encryption information when the protocol is SRT_PUSH.
backup_urls	No	Array of strings	Standby streaming URL list
stream_id	No	String	Stream ID of the streaming URL in an SRT_PULL channel.
latency	No	Integer	Stream pull latency of an SRT_PULL channel.

width	No	Integer	Width corresponding to the resolution. This parameter is optional. Value range: 0–4096 (4K)
height	No	Integer	Height corresponding to the resolution. This parameter is optional. Value range: 0–2160 (4K)
bitrate_for3u8	No	Boolean	Whether to use bitrate to fix the bitrate. Default value: false
passphrase	No	String	Encryption information when the protocol is SRT_PUSH

stream_id	No	String	Stream ID of the streaming URL in an SRT_PULL channel.
latency	No	Integer	Stream pull latency of an SRT_PULL channel.

**Table 7** FailoverConditions
Parameter	Mandatory	Type	Description
input_loss_threshold_msec	No	Integer	Duration threshold for stopping input streams. When the threshold is reached, the primary/standby switchover is automatically triggered. Unit: millisecond. Value range: 0–3,600,000 (Optional) The default value is 2,000 ms.
input_preference	No	String	Whether the primary ingest URL has the highest priority (PRIMARY) or the primary and standby URLs are switched equally (EQUAL). In the equal switchover mode, the standby URL is used and will not be automatically switched to the primary URL. (Optional) The default value is EQUAL.

**Table 8** InputAudioSelector
Parameter	Mandatory	Type	Description
name	Yes	String	Name of an audio selector. Enter only letters, digits, hyphens (-), and underscores (_). The name of each selector must be unique within the same channel.

If there is no audio stream in English, the audio stream with the lowest PID will be selected. STRICT: strict match. For example, if the language code eng is selected, only an audio stream in English will be selected. If there is no audio stream in English, a muted segment will be automatically added. When this audio selector is used to play the video, the video is muted.

Parameter	Mandatory	Type	Description
pid	Yes	Integer	Sets the PID value.

**Table 12** AudioSelectorHlsSelection
Parameter	Mandatory	Type	Description
name	Yes	String	HLS audio selector name
