Thank you sir,
Sir,
Right now i am trying this example. It Showing multiple error for header files. I added complete path for this header file then it resolve it. Sir, Suppose "one.h" showing error then i add complete path it resolves. But after some time it shows error in the "One.h" included header file. I also solve that.. But now system give errors in the code of that example in each line...So can you send me small demo application on my mail "dangat123suraj@gmail.com" . please sir....Help me to solve this problem...thanks in advance.

Try copying the example from the examples folder to your development folder. This sometimes helps with path issues, as then the project file should have correct paths.

Sir i am doing what you have told.
It shows error in ui_main_ui file that for include statement of "qcameraviewfinder.h". To solve this i locate this file and add path forr this file for QT5. Then it showing error for diffrent header files.
ui_main_ui:-
A. qcamerafinder.h:-
1.qmediacontrol.h:-
i. qmediacontrol.h
2.qmediaobjects.h:-
i. qtmultimediadefs.h
ii.qmultimedia.h:-
a. qtmultimediadefs.h
3.qmediaservice.h:-
i. qtmultimediadefs.h
ii.qmediacontrol.h
4. qvideowidget.h:-
i.qwidget.h
ii. qtmultimediawidgetdefs.h
iii.qmediabindableinterface.h:-
a. qmediaobject.h

Above .h files problem came. I locate this files and add path for it(Select QT5 file)

Now i got the last error for viewfinder which is unsolved yet for line
"viewfinder = new QCameraviewfinder(tab);"

Error as undefined refarance to viewfinder

Can any body tell me how to solve this?

What version of Qt are you getting this code from ? And what exact version of Qt are you using ?

[Suraj]

Sir,
I am using QT Creator 3.2.2
and it is based on Qt versions 4.8.6 in path(system)
compiler= Gcc (x86 32 bit in /usr/lib/ccache)
debugger = system GDB at /usr/bin/gdb

Did you properly install your system Qt for development ?

sir, i have done recording video and capturing video by using following code. I just call this code by using slots of "capture image" and "record a video":
// For Video:-
system("ffmpeg -f video4linux2 -i /dev/video0 -vcodec mpeg4 -b 12000k -r 25 -t 00:00:55 test12.avi");

//For image capture:-
system("fswebcam -s 15 --jpeg 95 --save /abasfc.jpeg");

Sir, i just want view this particular item on GUI at the time of capturing image and recording video.. How to do that?
thanks in advance...

Either grab the Qt SDK installer or use Fedora's package manager to install Qt.
