I haven't talked to my new blog for a long time. I have been charging urgently in the last month and busy with some private affairs. However, my blog garden is still my favorite ~ I want to make statistics this time,Class Design, coding, and performance. What should your team do first? 1. First, design the architecture and consider changes, reuse and reuse as much as possible.--->Start coding again--->Fin

HEVC Video Coding FrameworkThe HEVC coding framework is similar to the H.26X standard coding framework, and is based on a mixed block model.Figure 1 HEVC Coding Framework1. First, the video encoder divides the input video image into a non-overlapping encoding unit.2. Then the predictive

But I try to be easy to write and I hope to be useful to other friends. Af

Strings are the most commonly used data types in Python, and many times you use characters that do not belong to the standard ASCII character set, and the code is likely to throw Unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0xc4 In position 10:ordinal not in range (128) exception. This anomaly is easy to come across in Python, especially in python2.x, a problem that puzzles beginners. However, if you understand Python Unicode and follow certain principles in

For Engineers familiar with the C/C ++ or Java language, JavaScript is flexible, easy to understand, and requires relatively loose code formats. It is easy to learn and use it in your own code. Because of this, JavaScript coding standards are often despised. Fixing and complementing during the development process will eventually become a nightmare for subsequent maintenance personnel. The long-term value of software is directly proportional to the

scheme, there are two problems to solve:A. How bytes are grouped, such as 8 bits or a set of bits, which is also known as the encoding unit.B. The mapping between the encoding unit and the character. For example, in ASCII code, the decimal 65 is mapped to the letter A.ASCII code is one of the most popular coding systems of the last century, at least in the west. Shows how the encoding units in the ASCII code are mapped to characters.The history of ch

For coding, each yard may have its own set of styles, many people may not care about the coding style at all, because the final compiler compiled by the target code will not be affected. But in the development of a large project, the most time-consuming cost is always the communication between the developers. Keeping your coding style consistent can greatly impro
