## Key Features
|
||||
|
||||
```bash
|
||||
pip install gradio_webrtc[stopword]
|
||||
```
|
||||
- 🗣️ Automatic Voice Detection and Turn Taking built-in, only worry about the logic for responding to the user.
|
||||
- 💻 Automatic UI - Use the `.ui.launch()` method to launch the webRTC-enabled built-in Gradio UI.
|
||||
- 🔌 Automatic WebRTC Support - Use the `.mount(app)` method to mount the stream on a FastAPI app and get a webRTC endpoint for your own frontend!
|
||||
- ⚡️ Websocket Support - Use the `.mount(app)` method to mount the stream on a FastAPI app and get a websocket endpoint for your own frontend!
|
||||
- 📞 Automatic Telephone Support - Use the `fastphone()` method of the stream to launch the application and get a free temporary phone number!
|
||||
- 🤖 Completely customizable backend - A `Stream` can easily be mounted on a FastAPI app so you can easily extend it to fit your production application. See the [Talk To Claude](https://huggingface.co/spaces/fastrtc/talk-to-claude) demo for an example on how to serve a custom JS frontend.

## Usage
|
||||
|
||||
This is an shortened version of the official [usage guide](https://freddyaboulton.github.io/gradio-webrtc/user-guide/).
|
||||
|
||||
To get started with WebRTC streams, all that's needed is to import the `WebRTC` component from this package and implement its `stream` event.
|
||||
|
||||
### Reply on Pause
|
||||
|
||||
Typically, you want to run an AI model that generates audio when the user has stopped speaking. This can be done by wrapping a python generator with the `ReplyOnPause` class
|
||||
and passing it to the `stream` event of the `WebRTC` component.
|
||||
|
||||
```py
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC, ReplyOnPause
|
||||
|
||||
def response(audio: tuple[int, np.ndarray]): # (1)
|
||||
"""This function must yield audio frames"""
|
||||
...
|
||||
for numpy_array in generated_audio:
|
||||
yield (sampling_rate, numpy_array, "mono") # (2)
|
||||
- `.ui.launch()`: Launch a built-in UI for easily testing and sharing your stream. Built with [Gradio](https://www.gradio.app/).
|
||||
- `.fastphone()`: Get a free temporary phone number to call into your stream. Hugging Face token required.
|
||||
- `.mount(app)`: Mount the stream on a [FastAPI](https://fastapi.tiangolo.com/) app. Perfect for integrating with your already existing production system.
|
||||
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
gr.HTML(
|
||||
"""
|
||||
<h1 style='text-align: center'>
|
||||
Chat (Powered by WebRTC ⚡️)
|
||||
</h1>
|
||||
"""
|
||||
)
|
||||
with gr.Column():
|
||||
with gr.Group():
|
||||
audio = WebRTC(
|
||||
mode="send-receive", # (3)
|
||||
modality="audio",
|
||||
)
|
||||
audio.stream(fn=ReplyOnPause(response),
|
||||
inputs=[audio], outputs=[audio], # (4)
|
||||
time_limit=60) # (5)
|
||||
## Quickstart
|
||||
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
1. The python generator will receive the **entire** audio up until the user stopped. It will be a tuple of the form (sampling_rate, numpy array of audio). The array will have a shape of (1, num_samples). You can also pass in additional input components.
|
||||
|
||||
2. The generator must yield audio chunks as a tuple of (sampling_rate, numpy audio array). Each numpy audio array must have a shape of (1, num_samples).
|
||||
|
||||
3. The `mode` and `modality` arguments must be set to `"send-receive"` and `"audio"`.
|
||||
|
||||
4. The `WebRTC` component must be the first input and output component.
|
||||
|
||||
5. Set a `time_limit` to control how long a conversation will last. If the `concurrency_count` is 1 (default), only one conversation will be handled at a time.
|
||||
|
||||
|
||||
### Reply On Stopwords
|
||||
|
||||
You can configure your AI model to run whenever a set of "stop words" are detected, like "Hey Siri" or "computer", with the `ReplyOnStopWords` class.
|
||||
|
||||
The API is similar to `ReplyOnPause` with the addition of a `stop_words` parameter.
|
||||
|
||||
|
||||
```py
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC, ReplyOnPause
|
||||
|
||||
def response(audio: tuple[int, np.ndarray]):
|
||||
"""This function must yield audio frames"""
|
||||
...
|
||||
for numpy_array in generated_audio:
|
||||
yield (sampling_rate, numpy_array, "mono")
|

)
|

with gr.Column():
|

with gr.Group():

audio = WebRTC(

|
||||
|
||||
1. The `stop_words` can be single words or pairs of words. Be sure to include common misspellings of your word for more robust detection, e.g. "llama", "lamma". In my experience, it's best to use two very distinct words like "ok computer" or "hello iris".
|
||||
|
||||
|
||||
### Audio Server-To-Clien
|
||||
|
||||
To stream only from the server to the client, implement a python generator and pass it to the component's `stream` event. The stream event must also specify a `trigger` corresponding to a UI interaction that starts the stream. In this case, it's a button click.
|
||||
|
||||
|
||||
|
||||
```py
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC
|
||||
from pydub import AudioSegment
|
||||
|
||||
def generation(num_steps):
|
||||
for _ in range(num_steps):
|
||||
segment = AudioSegment.from_file("audio_file.wav")
|
||||
array = np.array(segment.get_array_of_samples()).reshape(1, -1)
|
||||
yield (segment.frame_rate, array)
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
audio = WebRTC(label="Stream", mode="receive", # (1)
|
||||
modality="audio")
|
||||
num_steps = gr.Slider(label="Number of Steps", minimum=1,
|
||||
maximum=10, step=1, value=5)
|
||||
button = gr.Button("Generate")
|
||||
|
||||
audio.stream(
|
||||
fn=generation, inputs=[num_steps], outputs=[audio],
|
||||
trigger=button.click # (2)
|
||||
)
|
||||
```
|
||||
|
||||
1. Set `mode="receive"` to only receive audio from the server.
|
||||
2. The `stream` event must take a `trigger` that corresponds to the gradio event that starts the stream. In this case, it's the button click.
|
||||
|
||||
|
||||
### Video Input/Output Streaming
|
||||
Set up a video Input/Output stream to continuosly receive webcam frames from the user and run an arbitrary python function to return a modified frame.
|
||||
|
||||
```py
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC
|
||||
|
||||
|
||||
def detection(image, conf_threshold=0.3): # (1)
|
||||
... your detection code here ...
|
||||
return modified_frame # (2)
|
||||
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
image = WebRTC(label="Stream", mode="send-receive", modality="video") # (3)
|
||||
conf_threshold = gr.Slider(
|
||||
label="Confidence Threshold",
|
||||
minimum=0.0,
|
||||
maximum=1.0,
|
||||
step=0.05,
|
||||
value=0.30,
|
||||
)
|
||||
image.stream(
|
||||
fn=detection,
|
||||
inputs=[image, conf_threshold], # (4)
|
||||
outputs=[image], time_limit=10
|
||||
)
|
||||
|
||||
if __name__ == "__main__":
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
1. The webcam frame will be represented as a numpy array of shape (height, width, RGB).
|
||||
2. The function must return a numpy array. It can take arbitrary values from other components.
|
||||
3. Set the `modality="video"` and `mode="send-receive"`
|
||||
4. The `inputs` parameter should be a list where the first element is the WebRTC component. The only output allowed is the WebRTC component.
|
||||
|
||||
### Server-to-Client Only
|
||||
|
||||
Set up a server-to-client stream to stream video from an arbitrary user interaction.
|
||||
|
||||
```py
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC
|
||||
import cv2
|
||||
|
||||
def generation():
|
||||
url = "https://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/mux_sources/hevcds_720p30_2M.mp4"
|
||||
cap = cv2.VideoCapture(url)
|
||||
iterating = True
|
||||
while iterating:
|
||||
iterating, frame = cap.read()
|
||||
yield frame # (1)
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
output_video = WebRTC(label="Video Stream", mode="receive", # (2)
|
||||
modality="video")
|
||||
button = gr.Button("Start", variant="primary")
|
||||
output_video.stream(
|
||||
fn=generation, inputs=None, outputs=[output_video],
|
||||
trigger=button.click # (3)
|
||||
)
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
1. The `stream` event's `fn` parameter is a generator function that yields the next frame from the video as a **numpy array**.
|
||||
2. Set `mode="receive"` to only receive audio from the server.
|
||||
3. The `trigger` parameter the gradio event that will trigger the stream. In this case, the button click event.
|
||||
|
||||
|
||||
### Additional Outputs
|
||||
|
||||
In order to modify other components from within the WebRTC stream, you must yield an instance of `AdditionalOutputs` and add an `on_additional_outputs` event to the `WebRTC` component.
|
||||
|
||||
This is common for displaying a multimodal text/audio conversation in a Chatbot UI.
|
||||
|
||||
|
||||
|
||||
``` py title="Additional Outputs"
|
||||
from gradio_webrtc import AdditionalOutputs, WebRTC
|
||||
|
||||
def transcribe(audio: tuple[int, np.ndarray],
|
||||
transformers_convo: list[dict],
|
||||
gradio_convo: list[dict]):
|
||||
response = model.generate(**inputs, max_length=256)
|
||||
transformers_convo.append({"role": "assistant", "content": response})
|
||||
gradio_convo.append({"role": "assistant", "content": response})
|
||||
yield AdditionalOutputs(transformers_convo, gradio_convo) # (1)
|
||||
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
gr.HTML(
|
||||
"""
|
||||
<h1 style='text-align: center'>
|
||||
Talk to Qwen2Audio (Powered by WebRTC ⚡️)
|
||||
</h1>
|
||||
"""
|
||||
)
|
||||
transformers_convo = gr.State(value=[])
|
||||
with gr.Row():
|
||||
with gr.Column():
|
||||
audio = WebRTC(
|
||||
label="Stream",
|
||||
mode="send", # (2)
|
||||
modality="audio",
|
||||
)
|
||||
with gr.Column():
|
||||
transcript = gr.Chatbot(label="transcript", type="messages")
|
||||
|
||||
audio.stream(ReplyOnPause(transcribe),
|
||||
inputs=[audio, transformers_convo, transcript],
|
||||
outputs=[audio], time_limit=90)
|
||||
audio.on_additional_outputs(lambda s,a: (s,a), # (3)
|
||||
outputs=[transformers_convo, transcript],
|
||||
queue=False, show_progress="hidden")
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
1. Pass your data to `AdditionalOutputs` and yield it.
|
||||
2. In this case, no audio is being returned, so we set `mode="send"`. However, if we set `mode="send-receive"`, we could also yield generated audio and `AdditionalOutputs`.
|
||||
3. The `on_additional_outputs` event does not take `inputs`. It's common practice to not run this event on the queue since it is just a quick UI update.
|
||||

## Deployment
|
||||
|
||||
When deploying in a cloud environment (like Hugging Face Spaces, EC2, etc), you need to set up a TURN server to relay the WebRTC traffic.
|
||||
The easiest way to do this is to use a service like Twilio.
|
||||
### Echo Audio
|
||||
|
||||
```python
|
||||
from twilio.rest import Client
|
||||
import os
|
||||
from fastrtc import Stream, ReplyOnPause
|
||||
import numpy as np
|
||||
|
||||
account_sid = os.environ.get("TWILIO_ACCOUNT_SID")
|
||||
auth_token = os.environ.get("TWILIO_AUTH_TOKEN")
|
||||
def echo(audio: tuple[int, np.ndarray]):
|
||||
# The function will be passed the audio until the user pauses
|
||||
# Implement any iterator that yields audio
|
||||
# See "LLM Voice Chat" for a more complete example
|
||||
yield audio
|
||||
|
||||
client = Client(account_sid, auth_token)
|
||||
stream = Stream(
|
||||
handler=ReplyOnPause(echo),
|
||||
modality="audio",
|
||||
mode="send-receive",
|
||||
)
|
||||
```
|
||||
|
||||
token = client.tokens.create()

|

Parameters:
|
||||
value: path or URL for the default value that WebRTC component is going to take. Can also be a tuple consisting of (video filepath, subtitle filepath). If a subtitle file is provided, it should be of type .srt or .vtt. Or can be callable, in which case the function will be called whenever the app loads to set the initial value of the component.
|
||||
format: the file extension with which to save video, such as 'avi' or 'mp4'. This parameter applies both when this component is used as an input to determine which file format to convert user-provided video to, and when this component is used as an output to determine the format of video returned to the user. If None, no file format conversion is done and the video is kept as is. Use 'mp4' to ensure browser playability.
|
||||
height: The height of the component, specified in pixels if a number is passed, or in CSS units if a string is passed. This has no effect on the preprocessed video file, but will affect the displayed video.
|
||||
width: The width of the component, specified in pixels if a number is passed, or in CSS units if a string is passed. This has no effect on the preprocessed video file, but will affect the displayed video.
|
||||
label: the label for this component. Appears above the component and is also used as the header if there are a table of examples for this component. If None and used in a `gr.Interface`, the label will be the name of the parameter this component is assigned to.
|
||||
every: continously calls `value` to recalculate it if `value` is a function (has no effect otherwise). Can provide a Timer whose tick resets `value`, or a float that provides the regular interval for the reset Timer.
|
||||
inputs: components that are used as inputs to calculate `value` if `value` is a function (has no effect otherwise). `value` is recalculated any time the inputs change.
|
||||
show_label: if True, will display label.
|
||||
container: if True, will place the component in a container - providing some extra padding around the border.
|
||||
scale: relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True.
|
||||
min_width: minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first.
|
||||
interactive: if True, will allow users to upload a video; if False, can only be used to display videos. If not provided, this is inferred based on whether the component is used as an input or output.
|
||||
visible: if False, component will be hidden.
|
||||
elem_id: an optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles.
|
||||
elem_classes: an optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles.
|
||||
render: if False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later.
|
||||
key: if assigned, will be used to assume identity across a re-render. Components that have the same key across a re-render will have their value preserved.
|
||||
mirror_webcam: if True webcam will be mirrored. Default is True.
|
||||
rtc_configuration: WebRTC configuration options. See https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection/RTCPeerConnection . If running the demo on a remote server, you will need to specify a rtc_configuration. See https://freddyaboulton.github.io/gradio-webrtc/deployment/
|
||||
track_constraints: Media track constraints for WebRTC. For example, to set video height, width use {"width": {"exact": 800}, "height": {"exact": 600}, "aspectRatio": {"exact": 1.33333}}
|
||||
time_limit: Maximum duration in seconds for recording.
|
||||
mode: WebRTC mode - "send-receive", "receive", or "send".
|
||||
modality: Type of media - "video" or "audio".
|
||||
rtp_params: See https://developer.mozilla.org/en-US/docs/Web/API/RTCRtpSender/setParameters. If you are changing the video resolution, you can set this to {"degradationPreference": "maintain-framerate"} to keep the frame rate consistent.
|
||||
icon: Icon to display on the button instead of the wave animation. The icon should be a path/url to a .svg/.png/.jpeg file.
|
||||
icon_button_color: Color of the icon button. Default is var(--color-accent) of the demo theme.
|
||||
pulse_color: Color of the pulse animation. Default is var(--color-accent) of the demo theme.
|
||||
button_labels: Text to display on the audio or video start, stop, waiting buttons. Dict with keys "start", "stop", "waiting" mapping to the text to display on the buttons.
|
||||
icon_radius: Border radius of the icon button expressed as a percentage of the button size. Default is 50%

The WebRTC component supports the following three use cases:
|

1. [Streaming video from the user webcam to the server and back](#h-streaming-video-from-the-user-webcam-to-the-server-and-back)
|

4. [Streaming Audio from the client to the server and back (conversational AI)](#h-conversational-ai)
|
||||
|
||||
|
||||
## Streaming Video from the User Webcam to the Server and Back
|
||||
|
||||
```python
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC
|
||||
|
||||
|
||||
def detection(image, conf_threshold=0.3):
|
||||
... your detection code here ...
|
||||
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
image = WebRTC(label="Stream", mode="send-receive", modality="video")
|
||||
conf_threshold = gr.Slider(
|
||||
label="Confidence Threshold",
|
||||
minimum=0.0,
|
||||
maximum=1.0,
|
||||
step=0.05,
|
||||
value=0.30,
|
||||
)
|
||||
image.stream(
|
||||
fn=detection,
|
||||
inputs=[image, conf_threshold],
|
||||
outputs=[image], time_limit=10
|
||||
)
|
||||
|
||||
if __name__ == "__main__":
|
||||
demo.launch()
|
||||
|
||||
```
|
||||
* Set the `mode` parameter to `send-receive` and `modality` to "video".
|
||||
* The `stream` event's `fn` parameter is a function that receives the next frame from the webcam
|
||||
as a **numpy array** and returns the processed frame also as a **numpy array**.
|
||||
* Numpy arrays are in (height, width, 3) format where the color channels are in RGB format.
|
||||
* The `inputs` parameter should be a list where the first element is the WebRTC component. The only output allowed is the WebRTC component.
|
||||
* The `time_limit` parameter is the maximum time in seconds the video stream will run. If the time limit is reached, the video stream will stop.
|
||||
|
||||
## Streaming Video from the server to the client
|
||||
|
||||
```python
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC
|
||||
import cv2
|
||||
|
||||
def generation():
|
||||
url = "https://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/mux_sources/hevcds_720p30_2M.mp4"
|
||||
cap = cv2.VideoCapture(url)
|
||||
iterating = True
|
||||
while iterating:
|
||||
iterating, frame = cap.read()
|
||||
yield frame
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
output_video = WebRTC(label="Video Stream", mode="receive", modality="video")
|
||||
button = gr.Button("Start", variant="primary")
|
||||
output_video.stream(
|
||||
fn=generation, inputs=None, outputs=[output_video],
|
||||
trigger=button.click
|
||||
)
|
||||
|
||||
if __name__ == "__main__":
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
* Set the "mode" parameter to "receive" and "modality" to "video".
|
||||
* The `stream` event's `fn` parameter is a generator function that yields the next frame from the video as a **numpy array**.
|
||||
* The only output allowed is the WebRTC component.
|
||||
* The `trigger` parameter the gradio event that will trigger the webrtc connection. In this case, the button click event.
|
||||
|
||||
## Streaming Audio from the Server to the Client
|
||||
|
||||
```python
|
||||
import gradio as gr
|
||||
from pydub import AudioSegment
|
||||
|
||||
def generation(num_steps):
|
||||
for _ in range(num_steps):
|
||||
segment = AudioSegment.from_file("/Users/freddy/sources/gradio/demo/audio_debugger/cantina.wav")
|
||||
yield (segment.frame_rate, np.array(segment.get_array_of_samples()).reshape(1, -1))
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
audio = WebRTC(label="Stream", mode="receive", modality="audio")
|
||||
num_steps = gr.Slider(
|
||||
label="Number of Steps",
|
||||
minimum=1,
|
||||
maximum=10,
|
||||
step=1,
|
||||
value=5,
|
||||
)
|
||||
button = gr.Button("Generate")
|
||||
|
||||
audio.stream(
|
||||
fn=generation, inputs=[num_steps], outputs=[audio],
|
||||
trigger=button.click
|
||||
)
|
||||
```
|
||||
|
||||
* Set the "mode" parameter to "receive" and "modality" to "audio".
|
||||
* The `stream` event's `fn` parameter is a generator function that yields the next audio segment as a tuple of (frame_rate, audio_samples).
|
||||
* The numpy array should be of shape (1, num_samples).
|
||||
* The `outputs` parameter should be a list with the WebRTC component as the only element.
|
||||
|
||||
## Conversational AI
|
||||
|
||||
```python
|
||||
import gradio as gr
|
||||
import numpy as np
|
||||
from gradio_webrtc import WebRTC, StreamHandler
|
||||
from queue import Queue
|
||||
import time
|
||||
|
||||
|
||||
class EchoHandler(StreamHandler):
|
||||
def __init__(self) -> None:
|
||||
super().__init__()
|
||||
self.queue = Queue()
|
||||
|
||||
def receive(self, frame: tuple[int, np.ndarray] | np.ndarray) -> None:
|
||||
self.queue.put(frame)
|
||||
|
||||
def emit(self) -> None:
|
||||
return self.queue.get()
|
||||
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
with gr.Column():
|
||||
with gr.Group():
|
||||
audio = WebRTC(
|
||||
label="Stream",
|
||||
rtc_configuration=None,
|
||||
mode="send-receive",
|
||||
modality="audio",
|
||||
)
|
||||
|
||||
audio.stream(fn=EchoHandler(), inputs=[audio], outputs=[audio], time_limit=15)
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
* Instead of passing a function to the `stream` event's `fn` parameter, pass a `StreamHandler` implementation. The `StreamHandler` above simply echoes the audio back to the client.
|
||||
* The `StreamHandler` class has two methods: `receive` and `emit`. The `receive` method is called when a new frame is received from the client, and the `emit` method returns the next frame to send to the client.
|
||||
* An audio frame is represented as a tuple of (frame_rate, audio_samples) where `audio_samples` is a numpy array of shape (num_channels, num_samples).
|
||||
* You can also specify the audio layout ("mono" or "stereo") in the emit method by retuning it as the third element of the tuple. If not specified, the default is "mono".
|
||||
* The `time_limit` parameter is the maximum time in seconds the conversation will run. If the time limit is reached, the audio stream will stop.
|
||||
* The `emit` method SHOULD NOT block. If a frame is not ready to be sent, the method should return None.
|
||||
|
||||
## Deployment
|
||||
|
||||
When deploying in a cloud environment (like Hugging Face Spaces, EC2, etc), you need to set up a TURN server to relay the WebRTC traffic.
|
||||
The easiest way to do this is to use a service like Twilio.
|
||||
|
||||
```python
|
||||
from twilio.rest import Client
|
||||
import os
|
||||
|
||||
account_sid = os.environ.get("TWILIO_ACCOUNT_SID")
|
||||
auth_token = os.environ.get("TWILIO_AUTH_TOKEN")
|
||||
|
||||
client = Client(account_sid, auth_token)
|
||||
|
||||
token = client.tokens.create()
|
||||
|
||||
rtc_configuration = {
|
||||
"iceServers": token.ice_servers,
|
||||
"iceTransportPolicy": "relay",
|
||||
}
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
...
|
||||
rtc = WebRTC(rtc_configuration=rtc_configuration, ...)
|
||||
...

* Set the `mode` parameter to `send-receive` and `modality` to "video".
|
||||
* The `stream` event's `fn` parameter is a function that receives the next frame from the webcam
|
||||
as a **numpy array** and returns the processed frame also as a **numpy array**.
|
||||
* Numpy arrays are in (height, width, 3) format where the color channels are in RGB format.
|
||||
* The `inputs` parameter should be a list where the first element is the WebRTC component. The only output allowed is the WebRTC component.
|
||||
* The `time_limit` parameter is the maximum time in seconds the video stream will run. If the time limit is reached, the video stream will stop.

## Streaming Video from the server to the client
|
||||
|
||||
```python
|
||||
import gradio as gr
|
||||
from gradio_webrtc import WebRTC
|
||||
import cv2
|

|
||||
iterating = True
|
||||
while iterating:
|
||||
iterating, frame = cap.read()
|
||||
yield frame
|
||||
|

trigger=button.click
|
||||
)
|
||||
|
||||
if __name__ == "__main__":
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
* Set the "mode" parameter to "receive" and "modality" to "video".
|
||||
* The `stream` event's `fn` parameter is a generator function that yields the next frame from the video as a **numpy array**.
|
||||
* The only output allowed is the WebRTC component.
|
||||
* The `trigger` parameter the gradio event that will trigger the webrtc connection. In this case, the button click event.
|
||||
|
||||
## Streaming Audio from the Server to the Client
|
||||
|
||||
```python
|
||||
import gradio as gr
|
||||
from pydub import AudioSegment
|
||||
|
||||
def generation(num_steps):
|
||||
for _ in range(num_steps):
|
||||
segment = AudioSegment.from_file("/Users/freddy/sources/gradio/demo/audio_debugger/cantina.wav")
|
||||
yield (segment.frame_rate, np.array(segment.get_array_of_samples()).reshape(1, -1))
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
audio = WebRTC(label="Stream", mode="receive", modality="audio")
|
||||
num_steps = gr.Slider(
|
||||
label="Number of Steps",
|
||||
minimum=1,
|
||||
maximum=10,
|
||||
step=1,
|
||||
value=5,
|
||||
)
|
||||
button = gr.Button("Generate")
|
||||
|
||||
audio.stream(
|
||||
fn=generation, inputs=[num_steps], outputs=[audio],
|
||||
trigger=button.click
|
||||
)
|
||||
```
|
||||
|
||||
* Set the "mode" parameter to "receive" and "modality" to "audio".
|
||||
* The `stream` event's `fn` parameter is a generator function that yields the next audio segment as a tuple of (frame_rate, audio_samples).
|
||||
* The numpy array should be of shape (1, num_samples).
|
||||
* The `outputs` parameter should be a list with the WebRTC component as the only element.

## Conversational AI
|
||||
|
||||
```python
|
||||
import gradio as gr
|
||||
import numpy as np
|
||||
from gradio_webrtc import WebRTC, StreamHandler
|
||||
from queue import Queue
|
||||
import time
|
||||
|
||||
|
||||
class EchoHandler(StreamHandler):
|
||||
def __init__(self) -> None:
|
||||
super().__init__()
|
||||
self.queue = Queue()
|
||||
|
||||
def receive(self, frame: tuple[int, np.ndarray] | np.ndarray) -> None:
|
||||
self.queue.put(frame)
|
||||
|
||||
def emit(self) -> None:
|
||||
return self.queue.get()
|
||||
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
with gr.Column():
|
||||
with gr.Group():
|
||||
audio = WebRTC(
|
||||
label="Stream",
|
||||
rtc_configuration=None,
|
||||
mode="send-receive",
|
||||
modality="audio",
|
||||
)
|
||||
|
||||
audio.stream(fn=EchoHandler(), inputs=[audio], outputs=[audio], time_limit=15)
|
||||
|
||||
|
||||
if __name__ == "__main__":
|
||||
demo.launch()
|
||||
```
|
||||
|
||||
* Instead of passing a function to the `stream` event's `fn` parameter, pass a `StreamHandler` implementation. The `StreamHandler` above simply echoes the audio back to the client.
|
||||
* The `StreamHandler` class has two methods: `receive` and `emit`. The `receive` method is called when a new frame is received from the client, and the `emit` method returns the next frame to send to the client.
|
||||
* An audio frame is represented as a tuple of (frame_rate, audio_samples) where `audio_samples` is a numpy array of shape (num_channels, num_samples).
|
||||
* You can also specify the audio layout ("mono" or "stereo") in the emit method by retuning it as the third element of the tuple. If not specified, the default is "mono".
|
||||
* The `time_limit` parameter is the maximum time in seconds the conversation will run. If the time limit is reached, the audio stream will stop.
|
||||
* The `emit` method SHOULD NOT block. If a frame is not ready to be sent, the method should return None.
|
||||
|
||||
## Deployment
|
||||
|
||||
When deploying in a cloud environment (like Hugging Face Spaces, EC2, etc), you need to set up a TURN server to relay the WebRTC traffic.
|
||||
The easiest way to do this is to use a service like Twilio.
|
||||
|
||||
```python
|
||||
from twilio.rest import Client
|
||||
import os
|
||||
|
||||
account_sid = os.environ.get("TWILIO_ACCOUNT_SID")
|
||||
auth_token = os.environ.get("TWILIO_AUTH_TOKEN")
|
||||
|
||||
client = Client(account_sid, auth_token)
|
||||
|
||||
token = client.tokens.create()
|
||||
|
||||
rtc_configuration = {
|
||||
"iceServers": token.ice_servers,
|
||||
"iceTransportPolicy": "relay",
|
||||
}
|
||||
|
||||
with gr.Blocks() as demo:
|
||||
...
|
||||
rtc = WebRTC(rtc_configuration=rtc_configuration, ...)

|
||||
|
||||
- Clone the repo - top right of the page click the vertical three dots and select "Clone repository"
|
||||
- Open the repo in a terminal and install the dependencies
|
||||
- Get a gemini API key [here](https://ai.google.dev/gemini-api/docs/api-key)
|
||||
- Create a `.env` file in the root of the repo and add the following:
|
||||
```
|
||||
GEMINI_API_KEY=<your_gemini_api_key>
|
||||
```
|
||||
- Run the app with `python app.py`
|
||||
- This will print the two URLs of the agents running locally
|
||||
- Use ngrok to exponse one agent to the internet. This is so that you can acces it from your phone
|
||||
- Use the ngrok URL to access the agent from your phone
|
||||
- Now, start the "teacher gemini" agent first. Then, start the "student gemini" agent. The student gemini will start talking to the teacher gemini. And the teacher gemini will respond!
|
||||
|
||||
Important:
|
||||
- Make sure the audio sources are not too close to each other or too loud. Sometimes that causes them to talk over each other..
|
||||
- Feel free to modify the `system_instruction` to change the behavior of the agents.
|
||||
- You can also modify the `voice_name` to change the voice of the agents.
|
||||
- Have fun!

# FastRTC POC
|
||||
A simple POC for a fast real-time voice chat application using FastAPI and FastRTC by [rohanprichard](https://github.com/rohanprichard). I wanted to make one as an example with more production-ready languages, rather than just Gradio.
|
||||
|
||||
## Setup
|
||||
1. Set your API keys in an `.env` file based on the `.env.example` file
|
||||
2. Create a virtual environment and install the dependencies
|
||||
```bash
|
||||
python3 -m venv env
|
||||
source env/bin/activate
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
3. Run the server
|
||||
```bash
|
||||
./run.sh
|
||||
```
|
||||
4. Navigate into the frontend directory in another terminal
|
||||
```bash
|
||||
cd frontend/fastrtc-demo
|
||||
```
|
||||
5. Run the frontend
|
||||
```bash
|
||||
npm install
|
||||
npm run dev
|
||||
```
|
||||
6. Go to the URL and click the microphone icon to start chatting!
|
||||
|
||||
7. Reset chats by clicking the trash button on the bottom right
|
||||
|
||||
## Notes
|
||||
You can choose to not install the requirements for TTS and STT by removing the `[tts, stt]` from the specifier in the `requirements.txt` file.
|
||||
|
||||
- The STT is currently using the ElevenLabs API.
|
||||
- The LLM is currently using the OpenAI API.
|
||||
- The TTS is currently using the ElevenLabs API.
|
||||
- The VAD is currently using the Silero VAD model.
|
||||
- You may need to install ffmpeg if you get errors in STT
|
||||
|
||||
The prompt can be changed in the `backend/server.py` file and modified as you like.
|
||||
|
||||
### Audio Parameters
|
||||
|
||||
#### AlgoOptions
|
||||
|
||||
- **audio_chunk_duration**: Length of audio chunks in seconds. Smaller values allow for faster processing but may be less accurate.
|
||||
- **started_talking_threshold**: If a chunk has more than this many seconds of speech, the system considers that the user has started talking.
|
||||
- **speech_threshold**: After the user has started speaking, if a chunk has less than this many seconds of speech, the system considers that the user has paused.
|
||||
|
||||
#### SileroVadOptions
|
||||
|
||||
- **threshold**: Speech probability threshold (0.0-1.0). Values above this are considered speech. Higher values are more strict.
|
||||
- **min_speech_duration_ms**: Speech segments shorter than this (in milliseconds) are filtered out.
|
||||
- **min_silence_duration_ms**: The system waits for this duration of silence (in milliseconds) before considering speech to be finished.
|
||||
- **speech_pad_ms**: Padding added to both ends of detected speech segments to prevent cutting off words.
|
||||
- **max_speech_duration_s**: Maximum allowed duration for a speech segment in seconds. Prevents indefinite listening.
|
||||
|
||||
### Tuning Recommendations
|
||||
|
||||
- If the AI interrupts you too early:
|
||||
- Increase `min_silence_duration_ms`
|
||||
- Increase `speech_threshold`
|
||||
- Increase `speech_pad_ms`
|
||||
|
||||
- If the AI is slow to respond after you finish speaking:
|
||||
- Decrease `min_silence_duration_ms`
|
||||
- Decrease `speech_threshold`
|
||||
|
||||
- If the system fails to detect some speech:
|
||||
- Lower the `threshold` value
|
||||
- Decrease `started_talking_threshold`
|
||||
|
||||
|
||||
## Credits:
|
||||
Credit for the UI components goes to Shadcn, Aceternity UI and Kokonut UI.

This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
|
||||
|
||||
## Getting Started
|
||||
|
||||
First, run the development server:
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
# or
|
||||
yarn dev
|
||||
# or
|
||||
pnpm dev
|
||||
# or
|
||||
bun dev
|
||||
```
|
||||
|
||||
Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
|
||||
|
||||
You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
|
||||
|
||||
This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
|
||||
|
||||
## Learn More
|
||||
|
||||
To learn more about Next.js, take a look at the following resources:
|
||||
|
||||
- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
|
||||
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
|
||||
|
||||
You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
|
||||
|
||||
## Deploy on Vercel
|
||||
|
||||
The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
|
||||
|
||||
Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
