Windows inter-process communication-named MPs queues and MPs queues
A named pipe communicates between processes through a network. It shields the underlying network protocol details. Without understanding the network protocol, we can also use named pipes to implement inter-process communication. Compared with Socket network communication, the name pipeline no longer needs to write authentication code. When

"I can build an MPS queue in a year. But this is not the best way to use my time. What I want to do is to teach you to build pipelines with others ...... Then you teach others ...... Then they will teach others ......
Until pipelines fill every village in the region ...... At last, every village in the world has pipelines ."

Python implements MPs queues and python implements MPs queues.
This article describes how to process pipelines in Python. Share it with you for your reference. The specific analysis is as follows:
What is the most amazing magic in Linux? I believe different people have different opinions, but if there is no pipeline, I am afraid that magic will be lost in the beautiful magic.

A pipeline stream can transmit binary data between two threads.
A pipe stream is like a pipe where data is input at one end and data is output at another end. Usually two different threads are used to control them.
The usage is as follows:

Today from Baidu music download some WMA format music files, but my player only support MP3 format files, then need to WMA conversion bit MP3 format, through the software provided by the following is really much easier

Modify wma tags in batches [original code-Modify from wmfsdk]
The Code was written when I made my own music site. I did not check it carefully and used it to modify the wma of nearly 70 thousand. No error was found in mp3. You can modify the parameters by yourself.
Efficiency: it takes more than three hours for 70 Gbit/s of 50 thousand music data to be optimized.

Make your Songbird (Linux) compatible with WMA, RM, and other formats-general Linux technology-Linux technology and application information. For more information, see the following. These formats are supported by default in Windows Songbird. However, in Linux, we cannot pre-install the tool because it avoids legal investigations. Therefore, we need to modify it. In fact, as long as your GStreamer supports all the formats, you can try the following met
Problem
You want to play an MP3 or WMA audio file in xNa.Solution
XNa can use the default content pipeline to load MP3 or WMA audio files to a song object. After loading, you can use the static mediaplayer class to play the song object.Working Principle
First, add the MP3 or WMA file to the xNa project. This is the same as adding an image. See tutorial 3-1. Th
I. Concepts
Inter-process communication is to spread or exchange messages between different processes. Pipelines, or anonymous pipelines, are one of the most common communication methods between processes in Linux. They are a channel for data flow between two processes. Advantages: ease of use; disadvantages: simple functions.
Pipelines are the original communication methods between processes in Linux/Unix systems. Data flows between processes in a data stream mode. The anonymous
The full name of WMA is Windows Media Audio, a new audio format that Microsoft has introduced as a MP3 format. Because WMA is more than MP3 in terms of compression ratio and sound quality, it is far better than RA (real Audio), which produces better sound quality even at lower sampling frequencies.
Microsoft said the WMA format has a considerable copyright prote

The intermediate media used for pipeline communication is a file, which is usually called a pipeline file. When two processes use pipeline files for communication, one
The process is a write process, and the other process is a read process. The write process writes information to the MPs queue file
To add a wma video file to the background using asp, the added video file is displayed on the foreground.

1 pipe (PIPE)
Pipelines are the oldest form of IPC in Unix systems, and all UNIX systems provide such communication mechanisms, including Linux. The following restrictions apply to using MPs pipelines:
1. due to historical reasons, the pipeline is half-duplex and data can only flow in one direction. To achieve bidirectional communication, you must create two pipelines.
2. Both parties of the pipeline communication must be kinship-related processes
converter operation is simple, the user can easily get started.
Quick-turn Video Converter operation Tutorial:
1, before the conversion of files, the user first to download and install a speed-to-video converter in the computer, download resources directly Baidu search software can be found.
2, open the installed speed to the video converter, you can see the main software interface, here we select the audio list.
In the aspect of audio conversion, the speed-to-video converter can quickly co
