What is the real-time audio and video SDK?

A real-time audio and video SDK (Software Development Kit) is a set of tools, libraries, and APIs that developers can use to integrate real-time audio and video communication capabilities into their applications. It enables features like live streaming, video conferencing, online gaming voice chat, and interactive broadcasting by handling tasks such as audio/video capture, encoding, decoding, transmission, and rendering. The SDK abstracts complex networking, synchronization, and media processing logic, allowing developers to focus on building user-facing features.

Key components of a real-time audio and video SDK include:

1. Media Capture & Rendering: Captures audio/video from devices (microphone, camera) and renders them on screens or speakers.
2. Encoding & Decoding: Compresses audio/video data for efficient transmission and decompresses it for playback.
3. Network Transmission: Manages low-latency, high-quality data transfer over the internet, often using protocols like WebRTC, RTP, or UDP.
4. Quality Optimization: Implements features like echo cancellation, noise suppression, adaptive bitrate, and packet loss recovery.

Example Use Cases:

• A video conferencing app (e.g., Zoom-like functionality) uses the SDK to enable multi-party audio/video calls.
• A live streaming platform integrates the SDK to allow broadcasters to stream in real time while viewers watch with minimal delay.
• An online education app uses it for interactive teacher-student video interactions.
