A quick search in the Web reveals that the number of the books that are related to Windows Device drivers can be counted with the fingers of one hand. even worse, most of the books are either too old (published before or around Windows 2000) and/or not easilyReadable. Another problem is that the Windows Driver Model (WDM) is becoming more complex as time passes, so the newer books are relatively more complex to read than the older ones.

service. The following is an example of the simplest Web server that simply returns a request link for any request:package mainimport ( "fmt" "html" "log" "net/http")func main() { http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path)) }) log.Fatal(http.ListenAndServe(":8080", nil))}Compiling This example will run the server and listen on port 8080. Try using http://localho
matching routing rule that handler represents the corresponding processing method for the routing rule, and the processing method has two parameters.
In the code example we write, the corresponding, pattern / handler corresponding sayHello , when we enter in the browser http://localhost:9090 , the method is triggered sayHello .
We DefaultServeMux will continue to follow the HandleFunc method, as follows:

management and operation mechanisms in the kernel, especially memory management, thread scheduling, and concurrency control.
When the Windows Kernel drivers are loaded into the kernel and started, they become part of the Windows Kernel. The interface functions in the driver are called by the kernel at the right time, this is the basic way for Windows drivers to work. Microsoft defines the WDM (Windows Driver Model) to define the driver structure and
Windows driver development and windows driver development
The previous article "Windows driver development-basics 2" has introduced the windows framework. What are the differences between WDF?
We know that in WDF, KMDF is required. KMDF is based on WDM.
WDM Driver Model
In the WDM driver model, each hardware device has at least two drivers. One of the drivers

If the MUX rate is 1000000bits/sec (meaning that the decoder is going to read the file at 1000000bits/sec rate ), the video rate is 2000000bits/sec (which m

One: FFmpeg's layered structure
When writing this article, let's outline the FFmpeg layering problem, which we summarize in accordance with the most common "transcoding program" and "Camera capture" and "player" three models.
1: transcoding
transcoding basic Flow: FLV Format Data-->H264/AAC data-->YUV/PCM data-->H264/AAC data-->mp4 format data.
A: We call the FLV format data or the MP4 format data This layer is called the

Unlike before, the new version go get can be signed at the end and @ used to specify versions.
It requires the warehouse must be in the format of the v1.2.0 tag, like v1.2 a few 0 is not possible, it must be a semantic, v prefixed version number.
