Wowza Video Intelligence Framework (VIF) REST API

The Video Intelligence Framework (VIF) adds real-time, AI-powered object detection, scene analysis, and event-driven intelligence to live video streams running on Wowza Streaming Engine (WSE).

This REST API lets you inspect system and per-stream status, read and update the default configuration, manage the active (in-memory) and saved (on-disk) configuration of individual streams, and retrieve annotated thumbnails.

VIF WSE plugin reference

Configuration hierarchy

Settings cascade through three levels of increasing specificity: Defaults (/v1/{server}/plugin/vif/config) → Stream pattern → Single stream. A more specific setting overrides a less specific one.

Active vs. saved configuration

  • Active config (/v1/{server}/plugin/vif/applications/{appName}/streams/{streamName}) is the configuration currently applied in memory to a running stream. Supports GET and PUT.

  • Saved config (/v1/{server}/plugin/vif/applications/{appName}/streams/{streamName}/config) is the persisted configuration in video-intelligence.json. Supports GET, PUT, POST, and DELETE.

Authentication

All requests use HTTP Basic authentication with Wowza Streaming Engine Manager credentials.

Bodyapplication/json
activeboolean

Set to true to register WSE with the VI service.

Default false
vi_servicestring or null

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

vi_service_api_keystring or null

API key for authentication with the VI service.

app_namestring or null

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

stream_namestring or null

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

vif_event_listenersArray of EventListener (objects) or object

Array (or map) of VIF event listeners to trigger.

One of:

Array (or map) of VIF event listeners to trigger.

rollup_batch_intervalinteger

Seconds to hold detections for rollup and batch events.

Default 2
grayscaledboolean

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

Default false
landscape_videoboolean

Whether the video is in landscape orientation.

Default true
object_analysisobject(ObjectAnalysis)

Object-detection configuration.

scene_analysisobject(SceneAnalysis)

Scene/VLM analysis configuration.

ignore_untracked_objectsboolean

Ignore untracked objects when a tracking_method is set.

Default false
frame_bufferinteger

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

Default 10
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.

Default true
catch_up_max_behind_secondsnumber or null

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).

Default false
use_transcoderboolean

Use the transcoder to grab frames.

Default true
inference_fpsinteger

Frames per second sent to inferencing when use_transcoder is true.

Default -1
inference_video_heightinteger

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

Default -1
frame_grab_intervalinteger

Seconds between grabbing a frame when use_transcoder is false.

Default 1
skip_framesinteger

Process every Nth frame.

save_imagesboolean

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

Default false
log_timinginteger

Debug: seconds between writing timing metrics. 0 disables.

Default 0
log_max_messagesinteger

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

Default 0
streamsArray of objects(VifConfig)

Per-stream configuration overrides.
