[Interest] Generating .avi or .mpg from Qt? (from sequence of QImages or QPixmaps)
We are generating on-screen animations in Qt 4.8.6 widgets on Windows (just redrawing, based on a repeating QTimer). Does Qt4 or Qt5 proper support (or will Qt5 soon support) generation of .mpg / .mpeg (MPEG) or .avi files for generated animations? I'm imagining that this would be done by providing a sequence of QImages or QPixmaps having consistent dimensions, perhaps with a specified frame rate. Short of that, are there any well supported third-party Qt packages for doing this?
