pipecat-anam 0.0.3

Anam video avatar service for Pipecat

Pipecat Anam Integration

Generate real-time video avatars for your Pipecat AI agents with Anam.

Maintainer: Anam (@anam-org)

Installation

pip install pipecat-anam

Or with uv:

uv add pipecat-anam

You'll also need Pipecat with the services you use (STT, TTS, LLM, transport). For this repo's examples:

uv sync --extra dev --extra example

That installs all required Pipecat extras (deepgram, cartesia, google, daily, runner, webrtc) plus local tooling.

If you prefer pip:

pip install -e ".[dev,example]"

If you are building your own pipeline, install only the Pipecat extras you need.

Prerequisites

• Anam API key
• API keys for STT, TTS, and LLM (e.g., Deepgram, Cartesia, Google)
• Daily.co API key for WebRTC transport (optional)

Usage with Pipecat Pipeline

The AnamVideoService wraps around Anam's Python SDK for a seamless integration with Pipecat to create conversational AI applications where an Anam avatar provides synchronized video and audio output while your application handles the conversation logic. The AnamVideoService iterates over the (decoded) audio and video frames from Anam and passes them to the next service in the pipeline.

enable_audio_passthrough=True bypasses Anam's orchestration layer and renders the avatar directly from TTS audio.

enable_session_replay=False disables session recording on Anam's backend.

from anam import PersonaConfig
from pipecat_anam import AnamVideoService

persona_config = PersonaConfig(
    avatar_id="your-avatar-id",
    enable_audio_passthrough=True,
)

anam = AnamVideoService(
    api_key=os.environ["ANAM_API_KEY"],
    persona_config=persona_config,
    api_base_url="https://api.anam.ai",
    api_version="v1",
)

pipeline = Pipeline([
    transport.input(),
    stt,
    context_aggregator.user(),
    llm,
    tts,
    anam,  # Video avatar (returns synchronized audio/video)
    transport.output(),
    context_aggregator.assistant(),
])

See example.py for a complete working example.

Video Post-Filter Example

The output transport scales the avatar resolution to the specified output resolution. This result in an amorphous scaling when the aspect ratios between output and avatar mismatch, i.e., the video is stretched or squeezed in on or both dimensions. To avoid this, you can apply a video post-processing filter to crop the avatar to the output aspect ratio.

example_video_post_filter.py adds a video post processing filter after AnamVideoService:

• It works on OutputImageRawFrame and does not depend on Anam internals.
• It assumes packed RGB24 bytes (format="RGB").
• It performs a centered crop to match the configured output aspect ratio.
• It does not scale. Pipecat output transport can still scale as needed.
• It is a no-op when source and target aspect ratios already match.

The reusable helper lives in examples/video_post_filter.py. The same helper can be used with any Pipecat service producing OutputImageRawFrame.

Running the Example

1. Install dependencies:

uv sync --extra dev --extra example

2. Set up your environment:

cp env.example .env
# Edit .env with your API keys

3. Run:

uv run python example.py -t daily

Or with the built-in WebRTC transport:

uv run python example.py -t webrtc

The bot will create a room (or use the built-in client) with a video avatar that responds to your voice.

To run the center-aspect post-filter example:

uv run python example_video_post_filter.py

or with the Daily transport:

uv run python example_video_post_filter.py -t daily

Compatibility

• Tested with Pipecat v0.0.100+
