This chapter introduces audio and video fundamentals, including:
- Raw YUV, RGB, PCM, and WAV data.
- The concepts of audio and video encoding and compression.
- A detailed analysis of the FLV, MP4, and TS container formats.
If you are reading this book, you probably have many years of internet experience and have certainly encountered everyday file formats such as MP3, MP4, and FLV. You have probably also used platforms such as Douyin and Kuaishou. I will not say much about current and future applications of audio and video technology; examples include video conferencing, remote driving, remote medical consultations, and virtual reality.
In short, audio and video development has a relatively high barrier to entry, but mastering it may lead to promotions, higher pay, and the peak of your career.
