The audio and video call SDK and the audio and video terminal SDK are closely related components in real-time communication systems, but they serve different purposes and are used in different layers of the application architecture.
Relationship Explanation:
-
Audio and Video Call SDK:
- This SDK provides core functionalities for establishing, managing, and maintaining real-time audio and video communication between users.
- It handles tasks such as signaling (call setup, teardown, and negotiation), media streaming (audio/video encoding/decoding), and network adaptation (handling packet loss, jitter, etc.).
- It is typically used by developers to integrate real-time communication features into applications like video conferencing, live streaming, or VoIP services.
-
Audio and Video Terminal SDK:
- This SDK focuses on the device-level interaction, providing APIs to access and manage hardware resources such as microphones, cameras, speakers, and displays.
- It ensures that audio and video data can be captured, rendered, and processed efficiently on the user's device (e.g., smartphones, PCs, or IoT devices).
- It is often used in conjunction with the call SDK to ensure smooth media input/output.
How They Work Together:
- The call SDK manages the communication logic (e.g., connecting two users, handling call signaling).
- The terminal SDK handles the media input/output (e.g., capturing video from a camera, playing audio through speakers).
- The call SDK relies on the terminal SDK to fetch and deliver media streams, while the terminal SDK depends on the call SDK for instructions on when and how to process media.
Example Use Case:
In a video conferencing app:
- The call SDK establishes a connection between two participants, negotiates codecs, and manages the call lifecycle.
- The terminal SDK captures the user's camera feed and microphone input, then renders the remote participant's video and audio on the screen and speakers.
