pipecat-anam 0.1.0a2

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)
• A Daily.co room and (optional) meeting tokens for Daily WebRTC transport — see Auto-provisioning the Daily room.

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 renders the avatar directly from your TTS audio (no separate Anam-side LLM or voice generation).

enable_session_replay=False disables Anam-side session recording.

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 examples/video-avatar-anam-video-service.py for a complete working example.

Initializing the Anam avatar session

AnamVideoService opens its connection to the Anam Backend asynchronously. The StartFrame is propagated downstream immediately so the rest of the pipeline (LLM/TTS/...) can warm up in parallel. TTS audio starts forwarding once the avatar is ready; any TTS produced before then is held back so it doesn't get dropped on the way in or accumulates latency.

Prior to v0.0.4, AnamVideoService blocked on StartFrame until the avatar was ready, which serialised pipeline startup. The async path keeps initial response latency low.

Publishing directly to Daily

[!WARNING] Direct Daily egress is experimental and only supported for Cara-4 avatars. The transport and signalling path will change in upcoming anam alpha releases. Pin to an exact alpha if you build on this; expect breaking changes between alphas.

AnamTransport is a drop-in replacement for Pipecat's DailyTransport. The Anam Backend publishes the avatar's synchronised audio and video directly into your Daily room, so the Pipecat bot doesn't have to receive and re-publish the avatar's A/V tracks.

The Daily room is bring-your-own: provision the room and mint two separate meeting tokens before starting the pipeline. See the Daily REST API docs for rooms and meeting-tokens (or use pipecat's Daily helpers).

• daily_avatar_token — for the Anam Backend (optional, but required for private rooms). If a user_name claim is set, it must match daily_avatar_user_name (or leave the claim empty). This lets the transport tell the avatar apart from end users. The transport will not forward TTS until the avatar has joined.
• daily_bot_token — for the Pipecat bot itself, used to capture the user's microphone for STT.

Requires anam==0.5.0a1 (pinned exactly — see the SDK's experimental-alpha warning).

from anam import PersonaConfig
from pipecat_anam import AnamTransport

transport = AnamTransport(
    api_key=os.environ["ANAM_API_KEY"],
    persona_config=PersonaConfig(
        avatar_id=os.environ["ANAM_AVATAR_ID"],
        # Direct Daily egress requires a Cara-4 avatar; stock avatars default to cara-3.
        avatar_model="cara-4-latest",
        enable_audio_passthrough=True,
    ),
    daily_room_url=os.environ["DAILY_ROOM_URL"],
    daily_bot_token=os.environ["DAILY_BOT_TOKEN"],
    daily_avatar_token=os.environ["DAILY_AVATAR_TOKEN"],
    daily_avatar_user_name=os.environ["DAILY_AVATAR_USER_NAME"],
)

Auto-provisioning the Daily room

AnamTransport does not mint Daily rooms or tokens itself. If you'd rather provision a room programmatically than pre-create one, use Pipecat's DailyRESTHelper with your DAILY_API_KEY to create the room and the two meeting tokens before constructing the transport:

import aiohttp
from pipecat.transports.daily.utils import (
    DailyMeetingTokenParams,
    DailyMeetingTokenProperties,
    DailyRESTHelper,
    DailyRoomParams,
)

async with aiohttp.ClientSession() as session:
    helper = DailyRESTHelper(
        daily_api_key=os.environ["DAILY_API_KEY"],
        aiohttp_session=session,
    )
    room = await helper.create_room(DailyRoomParams())
    avatar_token = await helper.get_token(
        room.url,
        params=DailyMeetingTokenParams(
            properties=DailyMeetingTokenProperties(user_name="anam-avatar"),
        ),
    )
    bot_token = await helper.get_token(room.url)

    transport = AnamTransport(
        api_key=os.environ["ANAM_API_KEY"],
        persona_config=PersonaConfig(
            avatar_id=os.environ["ANAM_AVATAR_ID"],
            # Direct Daily egress requires a Cara-4 avatar; stock avatars default to cara-3.
            avatar_model="cara-4-latest",
            enable_audio_passthrough=True,
        ),
        daily_room_url=room.url,
        daily_avatar_token=avatar_token,
        daily_bot_token=bot_token,
    )

Video Post-Filter Example

The output transport scales the avatar resolution to the configured output resolution. When the aspect ratios mismatch the video is stretched or squeezed. To avoid this, apply a video post-processing filter that crops the avatar to the output aspect ratio.

examples/video-avatar-anam-postfilter.py adds a CenterAspectCropFilter after AnamVideoService:

• Works on OutputImageRawFrame; does not depend on Anam internals.
• Assumes packed RGB24 bytes (format="RGB").
• Performs a centered crop to match the configured output aspect ratio.
• Does not scale. Pipecat's output transport can still scale as needed.
• No-op when source and target aspect ratios already match.

The filter is self-contained in that file and can be lifted into any Pipecat pipeline that produces 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 the AnamVideoService example (Pipecat's built-in transports):

uv run python examples/video-avatar-anam-video-service.py -t daily

Or with the built-in WebRTC transport:

uv run python examples/video-avatar-anam-video-service.py -t webrtc

To run the AnamTransport example (direct Daily egress, Deepgram + Google + Cartesia):

uv run python examples/video-avatar-anam-transport.py

To run the center-aspect post-filter example with the WebRTC transport:

uv run python examples/video-avatar-anam-postfilter.py -t webrtc

Or with the Daily transport:

uv run python examples/video-avatar-anam-postfilter.py -t daily

Compatibility

• Tested with Pipecat v0.0.100+
