On the afternoon of June 26, “ECUG Meetup 1st session · Hangzhou Station” invited Huo Kai, an audio and video client expert from Qiniuyun, to share on site. He who is “obsessed with simple, elegant and extremely human DESIGN SDK” 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 click the registration link directly) In order to help you better understand the details of the activity and the lecturer, ECUG campaign team conducted a simple interview with the lecturer, and the text is excerpted as follows:

One, personal article

1. Use three key words to introduce yourself

Sharing, long-termism, embracing change.

Use one sentence to introduce what you want to share

How a live audio and video SDK was designed, including the challenges encountered and how we solved them.

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

The SDK is the face of a technology service that will be directly available to our users. No matter how powerful the engine behind the service, it is essential that users access it correctly and quickly.

4. What defines a good SDK?

The interface is simple, the boundary is clear, extensible, and can be perceived.

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

If your boss writes code, that means he knows what you’re doing from a technical point of view, and if he happens to be the best in the industry, that means you’ll have a teacher who can guide you, which is good in every way.

Ii. Industry

1. With the development of audio and video technology, is there any phenomenon of “inner volume”? If so, what is it?

I don’t think there is any involume phenomenon. The products we export are technology and service. Competition can drive us to achieve the best product quality and user experience, and there is always room for improvement.

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 codec, echo cancellation, weak network transmission, etc., but the core solution is the problem of user experience, whether the picture is clear, whether there is noise, lag, screen and other phenomena. In my opinion, how to make the audio and video experience better under the circumstance of limited external conditions is the most core problem at this stage.

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

I would expect more intelligent applications, as we are already seeing powerful effects from the combination of audio and VIDEO and 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’m looking forward to seeing more scenes where audio and video are combined with AI in the future.

4. How to evaluate The RTC SDK of Qiniuyun?

After several iterations of large versions, the current SDK has a simple and extensible interface, supports multi-track, size stream, combined stream push and other features, and can perceive the audio and video quality of online users in real time.
