Java + FFMPEG generate video thumbnails

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.

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

1. Package test;
3. Import java. Io. ioexception;
5. Public class FFMPEG {
7. Public static void main (string [] ARGs ){
9. // Video file
11. String videorealpath = "f :\\ instant. FLV ";
13. // Path (output path)
15. String imagerealpath = "F: \ a.jpg ";
17. Try {
19. // Call the batch processing file
21. Runtime.getruntime(cmd.exe C ("CMD/C start F: \ FFMPEG. Bat" + videorealpath + "" + imagerealpath );
23. } Catch (ioexception e ){
25. // Todo auto-generated Catch Block
27. E. printstacktrace ();
29. }
31. }
33. }

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