Product: Visual Intelligence — Live Video Understanding Use case: Apply a custom AI prompt continuously to a live RTMP stream (e.g. captioning, activity recognition, custom monitoring), results to your callback every 5s Mode: Server-Pull (you give us an RTMP URL → we pull → results to your callback) Host: https://stream.memories.ai Auth: Authorization: sk-mavi-... (no Bearer prefix)

Start a real-time analysis session on a live RTMP video stream. The server pulls the stream, runs an AI model against each frame window using your custom user_prompt, and pushes results to your callback URL every few seconds.

Each API key supports a maximum of 4 concurrent streaming tasks. Billing occurs every 5 seconds per active stream. If a credit deduction fails, the stream is automatically terminated.

Request Example

import requests

url = "https://stream.memories.ai/v1/understand/streamConnect"
headers = {
    "Authorization": "sk-mavi-...",
    "Content-Type": "application/json"
}

payload = {
    "url": "rtmp://your.server/live/stream",
    "user_prompt": "What stage is the food preparation at? Is it ready to eat?",
    "system_prompt": "Track the current cooking progress.",
    "callback": "https://your.app/callback",
    "thinking": False
}

response = requests.post(url, headers=headers, json=payload)
print(response.json())  # {"status": 0, "task_id": "..."}

Parameters

url

string

required

RTMP stream URL for live video input (e.g. rtmp://your.server:1935/live/stream).

user_prompt

string

required

The analysis instruction applied to each frame window — e.g. "What is happening right now?".

system_prompt

string

required

Role or context for the AI — e.g. "You are a real-time video monitoring system.".

callback

string

required

Public URL to receive continuous analysis results. Called repeatedly throughout the stream lifetime.

thinking

boolean

default:"false"

Enable reasoning mode for deeper analysis.

{
  "status": 0,
  "task_id": "5347085a-1747-4731-bdde-3856d09502c4",
  "text": ""
}

Use the returned task_id to stop the stream via Stop Stream Video Understanding.

Callback Payload

Results are pushed to your callback URL continuously while the stream is active:

{
  "status": 0,
  "task_id": "5347085a-1747-4731-bdde-3856d09502c4",
  "data": {
    "text": "The chef is frying vegetables. The dish appears to be halfway done.",
    "timestamp": "2025-10-22T12:00:45Z"
  }
}

status

integer

0 = success, -1 = failure.

task_id

string

Identifies which stream this callback belongs to. Use this to stop the stream.

data.text

string

AI-generated analysis for the current frame window.

data.timestamp

string

UTC timestamp of the analysis frame.

Error Codes

Code	Meaning
`-1`	Invalid request or parameters
`1001`	Maximum concurrent streams reached (4 per key)
`2001`	Credit deduction failed — stream auto-terminated
`5000`	Internal server error

Billing

Charged every 5 seconds per active stream
If credit deduction fails, the stream stops automatically — recharge and call this endpoint again to resume
This API does not support video file uploads or historical playback — live RTMP only
