Description

Hi,

I'm using OpenCV-java(3.00) (selfcompiled version see issue #3460)
and the CV_CAP_PROP_FOURCC property gives me back 0 with certain Video formats.
I've tested Mpg-2,flash(.flv) and mp4 until now.

It opens every one of them, but only the .mp4 gave another value than 0-(avc1).

So I do not no if it is normal, or (OpenCV-)java specific..

Peter,

Thanks for posting the issue. As you mentioned in the #3460 not all HighGUI functionality is covered by the Java wrappers.

Unfortunately currently there are no people supporting the Java wrappers on regular basis. So you can help the project by contributing your fix. Please read more details on how to contribute here: http://code.opencv.org/projects/opencv/wiki/How_to_contribute

Thanks
