How to add new tabs and slider function to a video capture program using libv4l?

[A Former User]

I am working on developin a GUI for video feed using Qt libv4l library in ubuntu 12.04.
I have planned work with the following example-
http://qt-apps.org/content/show.php/qt+webcam+viewer+-+V4lCapture?content=126541

I have to make the following additions to the program-

1. Tab system-triggering this action would save the video feed till that point in a file and start a new feed from that point in a new tab.
2. Adding a slider to control the rewinf and forward function for the saved file.

So, can anyone help me with the above mentioned tasks with respect to the example given on the link. If possible pseudocodes might be a great help.

Hi,

For the tab part you can use a QTabWidget

For the slider control have a look at QtMultimedia/Phonon depending on your Qt version.

Hope it helps
