Converting Mat to IplImage in Java

edit

it's probably wise to stick to one wrapper library here. opencv's and the javacv wrappers are basically incompatible(as javacv is mostly wrapping the deprecated c-api).

So you are pretty much saying that is not possible to cast mat to IplImage?

don't know javacv too well, but definitely not from opencv's java wrappers

I am developing an app in java where you can detect faces and record the footage at the same time. I need Mat in order to make the detection work, but if i want to record live footage from web cam I need to IplImage and that crashes the app unless I have two web cams running at the same time working separately.

aww, i see. so writing to video files is what got you into using javacv ?

(no real good idea here)

No. Object detection and Facial recognition got me into it, but I also wanted to record the footage.

k,k. i see. you could clearly do the object detection from plain opencv, but face reco would need additional jni.

btw, you can do :

 byte[] pixels; // from iplimage, if there's such a thing
 Mat m = new Mat(h,w,type); 
 m.put(0,0,pixels);

but i don't know the other direction (to IplImage)
