SRT Ingest (Caller)
Calls a remote SRT listener to receive media streams
Component Configuration
| Option | Description | Required | Environment override |
|---|---|---|---|
id |
A unique identifier for the component instance |
✓ |
|
displayName |
The name shown in the Studio UI of this component |
✓ |
|
port |
The port this SRT input will connect to (default: 5001) |
✗ |
|
host |
The IP address/hostname this SRT input will connect to (default: "127.0.0.1") |
✗ |
|
passphrase |
Optional: Authentication for this SRT input |
✗ |
|
streamId |
Optional: StreamId to use when calling the remote listener |
✗ |
|
enabled |
enabled at start (default: true) |
✗ |
|
captureSchedule |
Also capture the future EIT schedule (not just now/next). The full schedule can be large, so this defaults to off. (default: false) |
✗ |
|
burstProtection |
Drop data until input is completely stable (default: true) |
✗ |
|
socketOptions |
Socket Options |
✗ |
|
timeDomain |
Optional: time domain for frame-accurate alignment with other inputs (Global Configuration → Time Domains) |
✗ |
|
streamMappings |
Configure which streams to accept from this input |
✗ |
|
sourceRecordingDirectory |
Record each source's transport stream, exactly as it arrives, to this directory: one <source name>.ts file per connected stream. An absolute path on the Norsk engine's filesystem, which must already exist. Leave unset to record nothing. |
✗ |
|
sourceRecordingMode |
Raw writes the bytes as they arrive; segmented cuts them into segments, each led by a copy of the source's PAT and PMT, so each plays on its own. (default: "raw") |
✗ |
|
healthPolicy |
Connection health: override the document-wide Input health policy, thresholds or sampling for this input. A caller has no publisher to refuse, so Enforce behaves as Alert here. |
✗ |
|

Additional notes about this component |
✗ |
|
Options with an environment override can be set when Studio starts, without
editing the workflow. |
Socket Options
| Option | Description | Required |
|---|---|---|
receiveLatency |
The latency value in the receiving direction of the socket (SRTO_RCVLATENCY) |
✗ |
peerLatency |
The latency value provided by the sender side as a minimum value for the receiver (SRTO_PEERLATENCY) |
✗ |
inputBandwidth |
Input bandwidth (SRTO_INPUTBW) |
✗ |
overheadBandwidth |
Overhead bandwidth (SRTO_OHEADBW) |
✗ |
maxBandwidth |
Max bandwidth (SRTO_MAXBW) |
✗ |
peerIdleTimeoutMs |
Peer Idle Timeout (Input only) |
✗ |
Health Policy
| Option | Description | Required |
|---|---|---|
mode |
Override the document-wide Input health policy for this input (default: "inherit") |
✗ |
thresholds |
Alert thresholds the engine judges connections against; blank fields use the recommended values |
✗ |
sampling |
How often the engine samples connection health |
✗ |
Time Domains
Environment override: GLOBAL_TIME_DOMAINS (sets this global option as a whole).
| Option | Description | Required |
|---|---|---|
id |
Domain ID. Inputs (and documents on the same engine) that use this ID share a coordinator. Letters, digits, dash and underscore. |
✓ |
mode |
How members of this domain are aligned. (default: "time_aligned_pts") |
✗ |
seiTimeoutMs |
Time-aligned (SEI timecode) only. How long (ms) a member waits for its first SEI-bearing frame before taking the action below. Blank = wait indefinitely. |
✗ |
onSeiTimeout |
Time-aligned (SEI timecode) only. Action when the SEI timeout elapses: fail the input, or demote it to default (uncoordinated) timing. (default: "fail") |
✗ |
walltimeThresholdMs |
GOP-aligned only. Walltime threshold (ms) for accepting a member's IDR against the rolling reference. Default 400 — keep under half the GOP duration. (default: 400) |
✗ |
