There is more involved in what you describes: - gstreamer - qtmultimedia - qtbase Qt 5.4 does not has support for GStreamer1.0 natively, there is a patch[1] for it. 1. https://github.com/meta-qt5/meta-qt5/blob/fido/recipes-qt/qt5/qtmultimedia/0001-Initial-porting-effort-to-GStreamer-1.0.patch For our customers needing GStreamer we have made a custom QtMultimedia 5.5 to work against Qt 5.4 and this proved to be working fine for our customers; I don't remember exactly what issues we had with the patch but we eventually moved for a custom version for this set of customers. -- Otavio Salvador O.S.
