The core functions of an audio and video call SDK include:
Real-time Audio/Video Transmission: Enables low-latency, high-quality voice and video communication between users.
Example: A video conferencing app uses the SDK to stream live audio and video during meetings.
Call Management: Handles call initiation, answering, hanging up, and switching between audio/video modes.
Example: A messaging app allows users to start a voice call with a single tap.
Network Adaptation: Optimizes audio/video quality based on network conditions (e.g., bandwidth, packet loss).
Example: The SDK automatically reduces video resolution during poor network conditions to maintain call stability.
Screen Sharing: Supports sharing screens or specific applications for collaboration.
Example: A remote work tool uses the SDK to let users share their desktop during team discussions.
Multi-Participant Support: Enables group calls with multiple participants (e.g., 1-on-1, group conferences).
Example: A social app hosts live audio rooms where up to 100 users can join simultaneously.
Encryption & Security: Ensures data privacy with end-to-end encryption and secure authentication.
Example: A healthcare app uses the SDK to protect sensitive patient consultations.
Cross-Platform Compatibility: Works across devices (iOS, Android, Windows, macOS) and browsers.
Example: A customer support platform integrates the SDK to offer consistent call experiences on all devices.
For cloud-based audio/video solutions, Tencent Cloud’s Real-Time Communication (TRTC) service provides a robust SDK with these features, optimized for scalability and low latency.
