In #177 u tell me to use

MultimediaObject object = new MultimediaObject(source);
MultimediaInfo mo = object.getInfo();

i used, but mo.getAudio() not null , have right infos. Then i want use ffprobe to checkout duration info, but Jave have not ffprobe command . Could u add ffprobe feature support?

[a-schild]

Adding ffprobe would almost double the size of the native jar's, since we will have to ship one more binary per platform. I think it would be better to enhance the MultimediaObject to do more work.

Pull requests welcome

[naffan2014]

As i known , if only use ffmpeg executeble cannot get more information about audio and video,so if not add ffprobe i can not do my work easily by enhance the MultimediaObject. But like u said , it exaclty doube size of the jar's . however if the need more and more about ffprobe , u may consider if add ffprobe in .

[a-schild]

I think it would be possible to create new jars for the ffprobe native jars and have them as optional dependencies....
