Decart Plugin for Vision Agents
Decart integration for Vision Agents framework, enabling real-time video restyling capabilities.
It enables features such as:
- Real-time video transformation using generative AI models
- Dynamic style changing via prompts
- Seamless integration with Vision Agents video pipeline
Installation
uv add "vision-agents[decart]"
# or directly
uv add vision-agents-plugins-decart
Usage
This example shows how to use the RestylingProcessor to transform a user's video feed in real-time.
from vision_agents.core import User, Agent
from vision_agents.plugins import getstream, gemini, decart
processor = decart.RestylingProcessor(
initial_prompt="Studio Ghibli animation style",
model="lucy_2_rt",
)
agent = Agent(
edge=getstream.Edge(),
agent_user=User(name="Styled AI"),
instructions="Be helpful",
llm=gemini.Realtime(),
processors=[processor],
)
Dynamic Prompt Updates
You can register a function to update the style prompt dynamically based on the conversation:
@llm.register_function(
description="Change the video style prompt"
)
async def change_style(prompt: str) -> str:
await processor.update_prompt(prompt)
return f"Style changed to: {prompt}"
Reference Images ("costumes")
For models like Lucy that accept a reference image, pass it at construction
time and/or swap it atomically with a prompt via update_state:
processor = decart.RestylingProcessor(
model="lucy_2_rt",
initial_prompt="A person wearing a superhero costume",
initial_image="./costumes/superhero.png", # your own reference image
)
# Later — atomically change prompt + reference image
await processor.update_state(
prompt="A person wearing a wizard robe",
image="./costumes/wizard.png",
)
# Image-only update
await processor.update_state(image=b"<raw image bytes>")
initial_image and update_state(image=...) accept bytes, a local file
path, an http(s) URL, a data: URI, or a raw base64 string.
Configuration
The plugin requires a Decart API key. You can provide it in two ways:
- Set the environment variable
DECART_API_KEY - Pass it directly to the constructor:
RestylingProcessor(api_key="...")
