Trying to capture QImage of video frame

Please be more precise. "Not working" doesn't say much. What are you getting ? A blank image ? A black image ? Funny colours ?

yes i am getting .png but i want data in rgb format. because raw data format is only allowed on my frame buffer to display.

You do realise that if you load your image again in a QImage, you'll get a RGB image ?
If you really want to save an RGB image then go for bitmap but beware, it's uncompressed.

You always take the same image from the list, check that your counter increments properly and that you indeed update the list.
On a side note, you should pass const reference to QImage parameters. That will save useless copies.

Thank you for reply and sorry for late response. Yes probably i am incrementing the counter properly. and sir I couldn't understand what you said about const reference to QImage parameter?

Use:
const QImage &imageas parameter -
