Introduction:
The outbreak of the epidemic in 2020 directly promoted the rapid growth of online video products such as conferences and education, and the development of audio and video was also pushed to the forefront. We invited Javen, IMWeb audio and video guru and one of the lecturers of the 2020 IMWeb Conf, to see what he thinks about front-end audio and video today.
The interviews
IMWeb: How many IMWeb CONF sessions have you experienced?
Javen: I’ve been with the team for 2 years. But I have been following a total of 4 IMWeb CONF sessions before coming to the team.
IMWeb: What would you like to say to the 2020 IMWeb CONF?
Javen: Pay attention to IMWeb CONF, and you will learn something.
IMWeb: What advice would you give to the students who are going to graduate and do front-end work?
Javen: The front end may seem simple, but the big front end covers a lot of areas, requiring both breadth and depth. I believe that as long as you keep learning and practicing, your technology will grow rapidly.
IMWeb: many students are unfamiliar with Web front-end audio and video, and feel relatively niche. Do you think it has become a mass technology?
Javen: It’s not just about Web audio and video technology per se, it’s more about the people who enjoy video in the browser becoming more accessible to the masses. As a matter of fact, from the 2G era to the 4G and 5G era, the media through which the public obtains information from the Internet has changed from original texts and texts to video media, such as short videos or even live broadcasts. On the other hand, we’ve gone from watching videos on apps to watching videos on the browser, and now it’s a better experience, even faster. You’ll see that Web audio and video is really becoming more popular. For developers, as long as there is a need for Web audio and video scenes, it will push the development of browser standards, which in turn will push cloud service vendors and developers to try to implement better experience solutions. On the front end, more and more developers are investing in Web audio and video development, which is no longer a niche technology at least.
IMWeb: What challenges do you face in your Web audio and video practice in 2020?
Javen: The biggest challenge is the pandemic, but also the opportunity. My own expectation is that when 5G breaks out, online education will be in great demand, just like telecommuting and online conferencing. When the school opening date is approaching, how to ensure the audio and video class experience on the Web end becomes urgent. Not only will millions of students be able to attend classes on our Web platform at the same time, but students will also be able to interact with their teachers by voice or video on the Web. Later, I will share how to choose the front-end live broadcast technology and how WebRTC technology is combined with other audio and video live broadcast solutions and implemented in different actual scenarios.
IMWeb: WebRTC was mentioned, what do you think about it?
Javen: PERSONALLY, I’m a big fan of this technology. The vision is for real-time audio and video communication on the web, and of course it’s a cross-platform solution. It’s been around for almost 10 years, but it’s only been in the last two or three years that it’s been commercially available. If you’re a normal front-end developer, you don’t need to fully understand the audio/video and delivery mechanics behind it to get started quickly. Of course, while it’s a good technology, it’s also relatively complex, and cost and technology upgrades are both metrics to evaluate if it’s really going to be used in business. But I think WebRTC, both on its own and in combination with other technologies, will stand out as speeds and standards continue to evolve.
IMWeb: What do you think is the future trend of audio and video on the Web?
Javen: It’s the end of the year, and a lot of tech developers are going to give their predictions. I tend to focus on cloud vendors’ technology trend predictions because they are always the most technology sensitive. I follow Tencent cloud leaders and learn from them that audio and video, especially live streaming, mainly focus on three directions: faster, cheaper and smarter.
Faster for Web audio and video, WebRTC is still the best at present, with the lowest delay in the level of 100 milliseconds, which is also the basis for real-time audio and video communication on the Web in the future, but it is also more expensive than CDN streaming media live. Tencent Cloud builds WebRTC fast live broadcast on the basis of CDN service, which also enables us to enjoy cheaper low-delay live broadcast service. Hope WebRTC can be reduced to the same price as ordinary CDN soon. In terms of being more intelligent, Web audio and video can mainly be combined with WASM in AI scenes, which may have some applications, such as face recognition, intelligent beauty, and even the improvement of picture quality by super segmentation algorithm, etc. I believe that in the near future, each of us will be accustomed to sharing a link to the real online education, conference, medical, games on the web side.
