On the afternoon of June 26, ** “ECUG Meetup Phase 1 · Hangzhou Station” invited Huo Kai, an audio and video client expert from Qiniuyun, to share live. “Addicted to the design of simple, elegant and extreme humanistic SDK”, he will take “Real-time audio and video SDK Design Practice” as the theme. Talk about the process, challenges and solutions of real-time AUDIO and video SDK architecture design. (Tips: You can scan the QR code at the end of the article or directly sign up the link ~)

In order to help you better understand the details of the activity and the lecturer, ECUG activity group specially conducted a simple interview with the lecturer, the text is excerpted as follows:

I. Personal chapter

1. Try using three key words to introduce yourself

Sharing, long-termism, embracing change.

2. Introduce what you want to share in one sentence

How a real-time AUDIO and video SDK was designed, including the challenges encountered and how we solved them.

3. **** is “obsessed with simple, elegant and extremely humanized SDK”. What is the reason?

The SDK is the face of a technical service that goes directly to our users. No matter how powerful the engine behind the service is, users need to access it correctly and quickly.

** What defines a good SDK?

Simple interface, clear boundary, extensible, perceptive.

Is it a good thing or a bad thing that your boss can write code?

If your boss writes code, that means he has a technical understanding of what you’re doing, and if he happens to be a technical genius in your industry, that means you’ll have a teacher who can mentor you, which is a good thing in every respect.

Ii. Industry

1. With the development of technology in audio and video field, are there any “roll-in” phenomena? What, if anything, is it?

We export technology and services. Competition pushes us to maximize product quality and user experience. And there is always room for improvement, which is also beneficial to users of our products.

2. What do you think is the core problem of audio and video technology at this stage?

There are many difficulties related to audio and video technology, such as encoding and decoding, echo cancellation, weak network transmission, etc., but the core is to solve the problem of user experience, whether the picture is clear, whether there is noise, stutters, splintered screen and other phenomena. In my opinion, how to make audio and video experience better under the circumstance of limited external conditions is the core issue at this stage.

3. What are your expectations for the future application of audio and video technology?

I would expect to see more intelligent applications, as we are already seeing powerful effects from the combination of audio and video capabilities with AI capabilities, such as audio and video + recommendation algorithms, and video surveillance + content recognition, which can quickly turn some products into industry benchmarks. So I expect to see more audio and video combined with AI in the future.

**4. ** How do you evaluate qiniuyun’s RTC SDK?

After several iterations of major versions, the SDK now has a simple and extensible interface, supports multi-track, large and small streaming, and combined streaming and pushing features, and can sense the audio and video quality of online users in real time.
