C # Methods for reading information such as width and height of a video

This article explains how C # reads the width and height of the video. Share to everyone for your reference. The implementation method is as follows:

READ: Read using ffmpeg, so you need to download FFmpeg first. There are many online resources.

You can read out the frame height and frame width information of the video by executing a cmd command via FFmpeg.

The effect is as follows:

You can see the frame height and frame width obtained in the Blue Line box.

The next thing is easy. Construct a command, and then execute it on OK. I haven't tested all the video formats, and I'm guessing that common formats should all be supported.

The code to execute the command is as follows:

The code is as follows:

<summary>

Execute a command

</summary>

<param name= "command" > Command</param> to execute

<param name= "Output" > Outputs </param>

<param name= "error" > Error </param>

public static void ExecuteCommand (String command,out string Output,out string error)

{

Try

{

Create a process

Process PC = new process ();

Pc. startinfo.filename = command;

Pc. Startinfo.useshellexecute = false;

Pc. Startinfo.redirectstandardoutput = true;

Pc. Startinfo.redirectstandarderror = true;

Pc. Startinfo.createnowindow = true;

Start process

Pc. Start ();

Preparing to read out the output stream and error stream

String outputdata = String. Empty;

String errordata = String. Empty;

Pc. Beginoutputreadline ();

Pc. Beginerrorreadline ();

Pc. Outputdatareceived + = (ss, ee) = =

{

Outputdata + = ee. Data;

};

Pc. Errordatareceived + = (ss, ee) = =

{

ErrorData + = ee. Data;

};

Waiting to exit

Pc. WaitForExit ();

Close process

Pc. Close ();

Return stream Results

output = Outputdata;

Error = ErrorData;

}

catch (Exception)

{

output = null;

Error = NULL;

}

}
