Stream Management

Get active stream configuration

Returns the configuration currently applied in memory to the running stream. The stream name may be a specific stream or a stream pattern (regex).

get/v1/{server}/plugin/vif/applications/{appName}/streams/{streamName}

Response

Active configuration returned successfully.

activeboolean

Set to true to register WSE with the VI service.

vi_servicestring nullable

WebSocket endpoint for the VI service, e.g. ws://HOST:PORT/ws/stream/.

vi_service_api_keystring nullable

API key for authentication with the VI service.

app_namestring nullable

Per-stream application name. If blank, applies to all applications.

stream_namestring nullable

Stream name or regex pattern to match incoming streams, e.g. objects.*.

rollup_batch_intervalinteger

Seconds to hold detections for rollup and batch events.

grayscaledboolean

Send/process frames as grayscale to reduce latency and traffic.

landscape_videoboolean

Whether the video is in landscape orientation.

ignore_untracked_objectsboolean

Ignore untracked objects when a tracking_method is set.

frame_bufferinteger

Size of the frame buffer holding frames to send to the VIF service.

catch_up_to_liveboolean

Scene/VLM only. When inference stays slower than real-time, skip the stale buffered backlog and resume at the live edge instead of letting latency grow.

catch_up_max_behind_secondsnumber nullable

Scene/VLM only. How far behind live (seconds) detections may fall before catch-up skips to live. Unset derives to the buffer headroom (~2s).

auto_frame_throttleboolean

Opt-in frame-rate throttle (all modes): reduce inference_fps when inference falls behind. Renamed from auto_scene_frame_throttle (still accepted on read).

use_transcoderboolean

Use the transcoder to grab frames.

inference_fpsinteger

Frames per second sent to inferencing when use_transcoder is true.

inference_video_heightinteger

Height of the video to be inferenced. -1 = source, 0 = model, >0 actual value.

frame_grab_intervalinteger

Seconds between grabbing a frame when use_transcoder is false.

skip_framesinteger

Process every Nth frame.

save_imagesboolean

Debug: save frames from the transcoder to /tmp/vif/<stream_name>.

log_timinginteger

Debug: seconds between writing timing metrics. 0 disables.

log_max_messagesinteger

Debug: max log messages to write for vif/ws/wss. -1 all, 0 disabled.
