This article introduces a small open-source project: TS Encapsulation Format analyzer. TS stands for MPEG 2 Transport Stream (MPEG2 transmission Stream), which is widely used in broadcast and television systems, such as digital TVs and IPTV. My project is not large and can be used to learn the TS Encapsulation Format Structure. In addition, it supports separating video streams and audio streams in TS. And the timestamp, PTS, and DTS of the output TS p

This article introduces a small open-source project: H.264 bitstream analyzer. In the course of learning, we have obtained a lot of resources from the open-source community, which is also a feedback to the open-source community. My project is not large and can be used to learn the H.264 code stream structure. Developed Using MFC of VC 2010. In the process of parsing the NAL of H.264, another open-source project is used: hsf-bitstream. The hsf-bitstre

With SPA, you can play a specific stream based on various types of changes (such as initialization parameter changes, optimizer statistics refresh, and database upgrades)SQL or the entire SQL load, and then generate a comparison report to help you evaluate their impact. In versions earlier than Oracle Database 11g, I must capture all SQL statements and trace and run these statements,Then get the execution plan-this is an extremely time-consuming and error-prone task. In the new version, we don't

We recommend a face analyzer website. Upload a face sticker to analyze the region where you are from, such as China, South Korea, Southeast Asia, Eastern Europe, and the Middle East. You can also provide your intelligence index, adventure index, ambition index, gay index, prestige, income, social affinity ..... Web: http://www.faceanalyzer.com After registration, you can find the person closest to you. My analysis results: 44% Korean/Japan56% Chin

When the program crashes, this is too important.New found a problem, incredibly in the electro-optical fire between China, the time changed from yesterday to today, but the value of the variable was taken yesterday, but the use of the time is already today, so that the conditions of judgment is wrong.And even more coincidentally, the start of the first task takes some time, so when judging the second program, it is today (normal), so the second program will not be triggered.More coincidentally,

.hprof) before and after operation, open with mat and get Histgram result6. Use the homepage field to filter the Histgram results and list the object instances of the class, and see that the collection of objects in the two tables is different in size, with one more homepage than before the operation, indicating there is a leak7. Compare the two lists to find an extra object and find out who strung the reference line, locating it, using the method of finding GC root.Ps:· A lot of times the heap

Writing analyzers hastwo different methods, one is to identify the words through DFA, and the other is to identify them by writing programs directly. This procedure uses DFA to identify the word.How to implement DFA, presumably consistent with the book, in the program, it uses a two-dimensional array to represent the state transformation matrix, and a one-dimensional array to represent the final state.A lexical editor to implement thefunctionThe main points include the following:Ability to ident

The next step is to make sure that you meet so many problems. I believe that there are more ways than difficulties. Come on. Copyright notice: This article blog original articles, blogs,

But the same thing is, it is triggered from the actual structure of the system to reduce the timing requirements of the whole system. When using these two commands, it is important to make sure that the design itself is in line with the requirements, otherwise it is easy to issue timing problems.There are also two other commands, namely Set_max_delay and Set_

Today, I am working on. NET ProgramWhen a virtual directory is added, the following error occurs: "analyzer error" --- "failed to load type". However, I tested it in Vs and found the relevant information online, after adding the bin folder under the virtual root directory, the problem still persists. It suddenly reminds me that there is such a setting in the virtual directory, as shown below: The default Asp.net version is 1.14322. I changed it

, the retained size is the sum of the memory that the object can be recycled to after it has been GC. For a better understanding of retained size, consider an example.The objects in memory are treated as nodes in, and objects and objects are referenced to each other. Here's a special node GC Roots, Positive solution! This is the beginning of reference chain.Starting with obj1, the middle blue node represents only objects that can be accessed directly or indirectly through OBJ1. Because it can be
