Hi all,

I'm searching a java library to calculate video file duration for all possible video formats (flv, mpeg, avi, mp4).
I've tried "getDuration()" (class player" into package javax.media) but it's wrong for my porpouse.

Peraphs jffmpeg (net.sourceforge.jffmpeg.VideoDecoder)?
Has someone ever tried it?
where can i Find some explampe code?

Thank you,
bye

Andrea

Hi,

I've used ffmpeg.exe. I execute this file and it returns a string with duration value inside.
There is ffmpeg version also for Mac and I select to execute ffmpeg.exe or ffmpeg according to os version.
Here the code:

Thank you very much. I have added code tags, which improve your post. Don’t use [b] or similar tags inside code tags.
 
It is sorta covered in the JavaRanch Style Guide.
