Internet giants are vying for it. Why are audio and video development engineers so scarce?

In recent years, the Internet has shown a rapid development trend, and the way of information dissemination and entertainment on the Internet has also developed from the initial words and pictures to the current audio and video. Nowadays, short videos such as Tik Tok and Aauto Quicker are in full swing, especially with the arrival of the 5G era, audio and video have gradually become a necessity in people's daily life. So now a large number of companies are looking for audio and video talents, and there may be 3-4 companies competing for slightly better audio and video talents.

Therefore, the demand for audio and video talents has also changed from the niche to the public, which is more the result of everyone's expectation of the future market. To make an inappropriate analogy, the emergence of 3G/4G contributed to the prosperity of mobile Internet in 10. The emergence of 5G will also promote the prosperity of the audio and video industry for at least 10 years, because audio and video will bring users a better and richer user experience in the 5G era.

As far as China is concerned, audio and video engineers are generally programmers who deal with coding and decoding but do not involve specific coding and decoding.

Audio and video engineers generally need to master the concepts of code stream and packet format, use open source audio and video codec library (such as x264) to complete audio and video coding and decoding, use open rendering interface to achieve audio and video rendering, use open source streaming media server or SDK that implements standard protocols (such as rtmp), or use their own private standard protocols or private protocols to complete audio and video transmission.

Core competitiveness: Audio and video are the pearls of current programs. Being proficient in audio and video means that you have got the tickets for Noah's Ark, so you don't have to worry about the future development. However, there is a threshold for audio and video, which is not something that Xiao Bai, who knows nothing, can easily learn. This is an industry where there is a big wage gap between others.

High-end talents are scarce: among many recruitment apps, Internet companies in first-tier cities such as Beishangguangshen and Shenzhen recruit audio and video posts all the year round, and it is not uncommon for audio and video posts with salaries ranging from 50W to 70W. Even so, it is often impossible to recruit people, and most of them are only entry-level audio and video developers with a monthly salary of 20,000-30,000, which shows the development prospects of the industry.

Slow technical iteration: H264 coding has been used for more than 20 years since 1995 became the standard. Audio and video are biased towards the underlying technology, which will not change much for many years.

Fresh interns who want to study audio and video, or want to change careers or jump ship for a raise because of poor industry prospects, can read and understand the following audio and video core knowledge points carefully. Mastering these technologies will greatly improve your audio and video technology level and help you win a high-paying invitation from big manufacturers.
