FFmpeg source code Simple analysis: Avformat_alloc_output_context2 ()

need to infer the output Avoutputformat based on the file format name or filename. Whether the output format is inferred from a file format name or a filename, a function Av_guess_format () is called. Let's take a look at the two important functions mentioned in the previous steps: Avformat_alloc_context () and Av_guess_format ().Avformat_alloc_context () Avformat_alloc_context () is a FFmpeg API, which is defined as follows.Avformatcontext *avformat_alloc_context (void) { avformatconte

Differences and discrimination between PNP and PNP

different. You need to pay attention to the accumulation of information during actual use. The commonly used imported tubes include the 90xx and 80xx series from South Korea and the 2sx series from Europe. In the series, the third character has the same meaning as the third character of the domestically produced tubes. The main reason for the difference between the current direction and the voltage is that the voltage is positive and negative. A "professional" is a "Polarity" problem. The opera

! The same is true for the drop-down!------- The upper PULL mode injects current into the device, and the drop-down mode is the output current.------- Weak and strong only have different resistance values for the pull-up resistor. There is no strict distinction between them.------- The capability of non-collector (or drain) open-circuit output circuits (such as common door circuits) to increase current and voltage is limited, the pull-up resistance function is mainly used for the output current

Capacitive Touch Key principle

At this stage, with the capacitive touch button in appearance and service life and other aspects are superior to the traditional mechanical keys, capacitive touch keys are increasingly widely used in the field, including home appliances, consumer electronics, industrial control and mobile equipment. In this paper, a specific capacitive touch switch chip SJT5104 introduces the basic working principle and material selection of capacitive touch button. a working principle There is an inductive capa

But one day my program might need such a variable (call it a variable) and assign an initial value when it is declared. After that, my program will not be able to assign it again at any other place. What should I do then? With a const. //************** const int IC = 20; ...

The struggle of a programmer (absolutely inspirational !)

I have been writing a real-time operating system kernel over the past few days. I will make it public later, hoping to do my part for the development of domestic it. Recently, I have seen that many students and friends have no direction, so I wrote my experiences and shared them with you. I hope I can help my friends who just like me a little bit. I have been studying and working in the IT industry for more than seven years. During this period, I used Web pages, wrote MIS, databases, and applica

Valuable materials-development history of TOUCH Technology

is not difficult to find that the consumer market with small size as the mainstream only has two options: Resistance Type and projection Capacitive Type. Although the former is cost-effective, however, poor optical performance and tolerance have long been criticized by the market. Although the latter has many advantages, there are only a few suppliers of real energy production, and the price is naturally quite expensive, so it is only seen in a few high-unit-price products. At present, the sma

What is boundary scan )?

Boundary Scan (Boundary Scan) is a testing technique proposed when traditional online testing is not suitable for large-scale, high-integration circuit testing, the shift register is placed between the internal logic of the IC and the pins of each device during the icdesign process ). each shift register is called a cell. These cells allow you to control and observe the status of each input/output pin. When these cells are connected together, a data r
