What is the difference between the audio and video call capability and the audio and video call SDK?

The audio and video call capability refers to the ability of a system or application to support real-time audio and video communication. This includes functionalities like voice calls, video calls, and sometimes additional features such as screen sharing or file transfer.

On the other hand, an audio and video call SDK (Software Development Kit) is a set of tools, libraries, and documentation that developers can use to integrate audio and video calling functionalities into their own applications. An SDK typically provides APIs (Application Programming Interfaces) that simplify the process of adding these capabilities, handling tasks like encoding and decoding media, managing network connections, and ensuring compatibility across different devices and platforms.

Example:

• Audio and Video Call Capability: A messaging app that allows users to make voice and video calls is demonstrating audio and video call capability.
• Audio and Video Call SDK: If a developer wants to add voice and video calling to their own app, they might use an SDK provided by a company like Tencent. This SDK would include pre-built components and instructions on how to use them, allowing the developer to quickly implement and customize the calling features in their app.

For developers looking to integrate audio and video calling into their applications, Tencent offers the Tencent Cloud Video SDK, which provides comprehensive solutions for real-time communication needs.
