+
+## Examples:
+1. [Object Detection from Webcam with YOLOv10](https://huggingface.co/spaces/freddyaboulton/webrtc-yolov10n) 📷
+2. [Streaming Object Detection from Video with RT-DETR](https://huggingface.co/spaces/freddyaboulton/rt-detr-object-detection-webrtc) 🎥

+4. [Conversational AI]()
+
+## Usage
+
+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)
+2. [Streaming Video from the server to the client](#h-streaming-video-from-the-server-to-the-client)
+3. [Streaming Audio from the server to the client](#h-streaming-audio-from-the-server-to-the-client)
+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
+

+
+* 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

+
+* 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.

+* 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.

+## Deployment
+

+The easiest way to do this is to use a service like Twilio.
