How to generate a thumbnail for a Java video

 

 

I found a lot of related information on the Internet.

But the problem persists.

I finally found it on the javaeye website today.

 

To facilitate searching for and helping friends who encounter the same problem in the future

Write a tutorial

 

 

You can use FFMPEG to generate thumbnails for uploaded videos.

I found out how to compile FFMPEG on the Internet.

But it's too complicated.

The compiled FFMPEG file is found on csdn.

Download

 

For everyone

I realized that FFmpeg is very powerful, and most popular video formats can generate thumbnails.

 

Start now

Download FFMPEG and decompress it.

Create a BAT file

Start

E:/FFMPEG/bin/ffmpeg.exe-I % 1-SS 20-vframes 1-R 1-Ac 1-AB 2-S 160*120-F image2 % 2

Exit

The meaning of using red bars

 

 

E:/FFMPEG/bin/ffmpeg.exe FFMPEG path

% 1% 2 is similar to the C language in that it is reserved for passing parameters.

20. How many seconds will the image be taken?

Open myeclipse and create a project and a Java File

Package test;

Import java. Io. ioexception;

Public class FFMPEG {

Public static void main (string [] ARGs ){

// Video file

String videorealpath = "F: // instantaneous. FLV ";

// Path (output path)

String imagerealpath = "F: // a.jpg ";

Try {

// Call the batch processing file

Runtime.getruntime(cmd.exe C ("CMD/C start F: // FFMPEG. Bat" + videorealpath + "" + imagerealpath );

} Catch (ioexception e ){

// Todo auto-generated Catch Block

E. printstacktrace ();

}

}

}

 

 

 

Run it and try again. You can see it in drive F.
