Preface
The Internet industry is currently developing rapidly, and various popular development majors are highly sought after in the early stages. However, with the popularization of technology and the saturation of talent in the market, recruitment requirements have gradually increased and competition has become increasingly fierce. Android development also faces such challenges.
Android Programmer Dilemma
When many people engage in Android development, they cherish the dream of becoming a senior architect and look forward to receiving generous salaries. However, the reality is not satisfactory. Currently, the Android market is facing many difficulties. Many major manufacturers have laid off employees, and the number of laid-off Android programmers has increased, making the market competition more intense. In addition, industry involution is serious, putting tremendous pressure on job seekers.
Nonetheless, employment prospects in other IT markets are equally grim. In the current economic situation, only by closely following national policies can we find better employment opportunities.
The sudden rise of short video and live broadcast industry
In recent years, the short video and live broadcast industry has suddenly emerged and become one of the most popular industries. With the trend of online life scenes, voice and video technology have been widely used in various fields.
Short video platforms such as Douyin and Kuaishou require image processing and video encoding technology to provide high-quality video content. Lianmai live broadcast and video conferencing require technical support such as RTC and transcoding confluence services to ensure a smooth and low-latency interactive experience. People's requirements for audio experience are also constantly increasing, requiring higher sound quality restoration and spatial audio rendering and other technologies.
Although the audio and video development industry has existed for a long time, the prospects for this industry are still very bright as the online market continues to expand and people's demand for real-time interactive experiences increases. At present, there are relatively few talents in the field of audio and video development, but the market demand is growing. Many SaaS platforms and major manufacturers are in urgent need of professionals with audio and video technology to solve sudden traffic problems.
Therefore, the audio and video development field is still a blue ocean with huge development potential and opportunities. In the future, with the continuous advancement of technology and the expansion of application scenarios, this industry will become even more popular. For those interested in audio and video development, now is the perfect time to join the field.
It can also be seen from the above pictures that audio and video development is still growing.
Although this technology is ubiquitous in our lives, in the future, this technology will be applied to a wider range of scenarios. By then, audio and video technical talents will become the new darling of the market. Although it is not easy to learn, the technology in this field is updated slowly and will not be easily eliminated. The accumulated experience will be a fulcrum for your greater future.
So far
I believe that students who have read this far have a deeper understanding of the employment prospects and salary benefits of audio and video development. The reason why audio and video technology is well-paid is mainly because the technology in this field is relatively difficult and requires a wealth of knowledge and skills. This includes not only the C++ programming language and H264 video encoding technology, but also a series of processes such as audio and video collection, transmission, decoding and rendering. However, information about audio and video technology on the Internet is relatively scarce, which poses certain challenges to learners.
As the left-eared mouse said: "Go to the source of knowledge to learn." For learners, finding high-quality information sources is crucial. Direct access to primary sources not only saves time but also ensures the accuracy and completeness of the information. In this process, students can boldly try and explore bravely. Whether they are working in the audio and video field or students who plan to change jobs, they should seize this rare opportunity.
Remember, every great achievement begins with a brave beginning. May you ride the wind and waves in this vast blue ocean and write your own glorious chapter.
