Overview

This endpoint is the entry point of the streaming lifecycle. It takes a source feed, one or more processing pipelines, and one or more output destinations, and returns a stream_id you use for every other lifecycle operation.

Supported source protocols: SRT is supported today. RTMP and HLS ingest are coming soon.

How a stream fits together

The request body is built from four blocks that reference each other by id:

Source

source_stream - the live feed to ingest, e.g. srt://ingest.example.com:9000. You can also use the play URL of a stream flow here.

Audio selections

audio_selections - name the audio track(s) of the source you want to process and declare their spoken language. Use Probe a Source Stream to discover tracks, or start with $first_audio.

Profiles and pipelines

processing_profiles define how audio is processed (demixing, transcription, translation, revoicing, each none, best_model, or fast_model). pipelines connect an audio selection to a profile and declare the output assets to produce, each with a language.

Targets

target_streams - where the processed output goes. At least one is required. Push to your own endpoint (SRT/RTMP), or let Camb.ai host the output for you (SRT listener or HLS recording).

Before you start

Collect the IDs the payload references:

Language IDs - GET /source-languages and GET /target-languages. Languages are numeric IDs; for example 1 is English (US) and 54 is Spanish (Spain).

The system handles multilingual inputs. If the source audio mixes several languages, set source_language to the main one spoken; the others are handled automatically.

Voice IDs (optional) - GET /list-voices. If you pass voice IDs, dubbed speech uses those fixed voices. If you leave them out, voices are cloned from the speakers in the source audio.
Dictionary IDs (optional) - GET /dictionaries for custom terminology, up to 5.

When passing fixed voice IDs, include voices of different genders and tones. The system matches each speaker in the source audio to the most suitable voice from your list, so a varied list produces better matches.

A pipeline that produces an audio output must also declare a subtitle output in the same pipeline; the transcript drives the dubbing. You do not have to route the subtitle asset to a target.

Example: dub a football match into Spanish

The example ingests the SRT feed of a football match, dubs the English commentary (1) into Spanish (54), and pushes the dubbed program (original video plus Spanish commentary) to an SRT destination of your own.

Fastest way to test: copy this payload, adjust it to your setup, and paste it into the Try it body - the form fields fill in automatically from the pasted JSON. Then press Send.

      "url": "srt://delivery.example.com:9100"
    }
  ]
}

Scheduling

Every stream needs an end_time (with its timezone); the stream stops automatically at that moment. start_time is optional: omit it to start right away, or set it to schedule the stream for later.

{
  "start_time": "2026-08-01T19:30:00Z",
  "end_time": "2026-08-01T21:45:00Z",
  "timezone": "UTC"
}

Scheduling rules:

Times are ISO 8601 with a UTC offset, and the timezone (IANA name) must match their offset.
start_time cannot be in the past and at most 7 days in the future.
end_time must be at least 15 minutes after the start.

To end a stream before its end_time, delete it. To extend or shorten a running stream, update its end_time.

Choosing targets

You want to…	Use
Push to your own SRT endpoint	`"type": 1` with your `url`
Push to an RTMP ingest (e.g. YouTube)	`"type": 2` (or `4` for YouTube) with the ingest `url`
Let viewers pull from Camb.ai over SRT	`"type": 6`, omit `url`; the play URL is returned
Get a Camb.ai-hosted HLS recording	`"type": 3`, omit `url`; the playback URL is returned

Each target lists inputs: pipeline outputs by asset_id, and untouched source tracks by passthrough_selector (e.g. v:0 for the video). Source tracks that are not replaced by a pipeline output are forwarded automatically unless you set passthrough_policy to none.

Errors

402 - Insufficient credits for the requested configuration.
422 - Validation error: missing required blocks, an id reference that doesn’t resolve (e.g. a pipeline referencing an unknown profile), invalid language IDs, or malformed URLs.

Probe a Source Stream - inspect the source before creating
Get Stream Status - monitor state and output URLs
Update a Stream - reschedule, reconfigure, or toggle dubbing live
Delete a Stream - terminate a running or scheduled stream
Create an SRT Flow - standing SRT endpoints usable as source or target

Authorizations

x-api-key

string

header

required

The x-api-key is a custom header required for authenticating requests to our API. Include this header in your request with the appropriate API key value to securely access our endpoints. You can find your API key(s) in the 'API' section of our studio website.

Body

application/json

Configuration for a live stream.

end_time

string<date-time>

required

When the stream stops, in ISO 8601 with a UTC offset. Required; must be at least 15 minutes after the start. To end a stream earlier, delete it; to change the end, patch it.

timezone

string

required

IANA time zone name (e.g. UTC, Europe/London) that start_time/end_time are expressed in. Its offset must match the timestamps.

audio_selections

AudioSelection · object[]

required

Named audio tracks of the source that pipelines process.

Minimum array length: 1

Hide child attributes

audio_selections.id

string

required

Your identifier for this selection, referenced by pipelines[].audio_selection.

audio_selections.source

string

required

Audio track selector. Accepts FFmpeg-style selectors (a:0, 1, eng, #0x1fe, i:301, optionally with a channel suffix like :ch0,1) or magic selectors ($first_audio, $second_audio, $last_audio). Use Probe a Source Stream to discover tracks.

audio_selections.source_language

integer

required

Language spoken on the selected track. If the audio mixes several languages, use the main one; multilingual input is handled automatically. Numeric language ID from GET /source-languages, e.g. 1 for English (US).

audio_selections.background

string | null
