Implement Video Input for ADK Web

[jwc2023]

Is your feature request related to a problem?

ADK Web currently does not support camera input — it lacks integration with browser-based APIs meaning users can’t capture or stream video data directly from the web interface..

Describe the solution you'd like

Implement camera input on adk web, similar to adk python's functionality. This feature will allow users to capture live video streams directly from their browser camera and make them accessible within the ADK Web runtime for multimodal agent use cases.

• Create a modular video input component in the ADK Web SDK.
• Enable data transfer to the ADK Web backend or runtime through existing message protocols.
• Testing & Validation.

Goal:

• To enable future multimodal agent features in browser environments.
