Double-digit GDP growth and low inflation rates have greatly boosted consumer spending. Many people said that the real post-war period in Japan started in 1955, and that year we invested the first transistor radio into the Japanese market. The country's GNP grew rapidly, with a growth rate of 10.8%. Japanese households needed every kind of goods, and at that time the

The recorder class is responsible for implementing all functions of soundrecorder. It contains a mediarecorder member and a mediaplayer member, and encapsulates the operations related to these two members. This class provides a series of interfaces to the soundrecorder class to control the recording and playing process. The following describes important members and methods.

Because you need to design a specific command class for each command, some systems may require a large number of specific command classes, which will affect the use of the command pattern.Scene:1, the system needs to decouple the request caller and the recipient, so that the caller and receiver do not interact directly; 2. The system needs to specify requests at different times, queue re
In the past two days, I have studied how to obtain data from the DirectShow device by using FFMPEG. Here I will record it for memo. The methods described in this article mainly correspond to Windows platforms.

After the command is executed, the output result is as follows (Note: Chinese devices may encounter garbled characters ). The name of the device displayed in the list is very important. You can enter "-F dshow-I video =" {Devi
