SDK is the facade of a technical service, which will directly face our users. No matter how powerful the engine behind this service is, correct and fast access is the prerequisite for users.

The interface is simple, the boundary is clear, extensible, and perceptible.

5. The boss can write code, is it a good thing or a bad thing?

The boss can write code, which means that the boss can understand what you are doing from a technical level. If it happens that the boss’s technology is a great god in the industry, it means that you will have an additional teacher who can guide you, no matter from which aspect Look, it's all good.

2. Industry

1. With the development of technology in the audio and video field, has there been some "involution" phenomenon? What is it if there is?

I don’t think there is any involution. The products we export are technology and services. Competition can prompt us to achieve the ultimate in product quality and user experience, and there is always room for improvement. This is also true for users who use our products. advantageous.

2. What do you think is the core issue 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 solution is the problem of user experience, whether the viewing picture is clear, whether there are noises, freezes, and screens. How to make the audio and video experience better under the limited external conditions is the core issue at this stage.

I will look forward to more intelligent applications. Now we have seen that the combination of audio and video and AI capabilities produces powerful effects, such as audio and video + recommendation algorithms, and video surveillance + content recognition, which can quickly make some products become industry benchmarks . So in the future, I look forward to seeing more scenarios where audio, video and AI are combined.

After several iterations of major versions, the current SDK has a simple and extensible interface, supports multi-track, large and small streams, combined reposting and other special functions, and can perceive the audio and video quality of online users in real time.
