openCV cvSaveImage and cvCvtColor crash on android -
i'm working on android version 2.3.5 , 4.0.4 both version crash on execution of same code. have been trying frame video, save it, , convert hsv.
(i posted same question on opencv website here)
this code , error get.
public void process(){ iplimage orgimg = this.getframe(2); cvsaveimage(environment.getexternalstoragedirectory().tostring() + "/opencv/orgimg.jpg", orgimg); iplimage hsv = hsv(orgimg); } private iplimage getframe(int id){ file testfile = new file(environment.getexternalstoragedirectory().getabsolutepath() + videofile); if(testfile.canread()){ ffmpegframegrabber grabber = new ffmpegframegrabber(testfile); try { grabber.start(); grabber.setframenumber(id); final int height=grabber.getimageheight(); final int width=grabber.getimagewidth(); iplimage frame = iplimage.create(width, height, 8, 4); frame = grabber.grab(); //grabber.stop(); return frame; } catch (exception e) { // todo auto-generated catch block e.printstacktrace(); } } return null; } private iplimage hsv(iplimage orgimg) { // 8-bit, 3- color =(rgb) iplimage imghsv = cvcreateimage(cvgetsize(orgimg), 8, 3); log.e(tag,"hsvthreshold - image size" + cvgetsize(orgimg)); cvcvtcolor(orgimg, imghsv, cv_bgr2hsv); return imghsv; } here logcat when cvsaveimage or cvcvtcolor executed on device running 4.0.4

i found issue, theory:
this code running through jni; therefore, when grab image , set equal image, passes pointer. additionally, because start grabber in getframe function, grabber gets destroyed when image returned, , weird reason memory gets flushed , passed pointer becomes useless.
the solution issue either set grabber global variable, pass grabber argument getframe function, or (weirdly) execute opencv operation touches memory before returning image (i.e. call cvcvsaveimage or cvcvtcolor on random not have related image).
i hope explanation makes sense, , not know if should reported bug though ?
