@drzony Thanks for your contribution in correcting proper use of iterators! While you are anyway fixing interators in the given file, would you mind having a check, if the use of interators in the other methods should be "improved" too?

Maybe in

• V4L2Grabber::discover()
• V4L2Grabber::enumVideoCaptureDevices() ?

Thank you!
