How do i go about resolving the issue any suggestions ?
Should I try to build meta-qt5 master branch which says qt5.5 has been ported or is it possible to find the recipe that you mentioned for custom qtmultimedia5.5

There is more involved in what you describes:
Qt 5.4 does not has support for GStreamer1.0 natively, there is a patch for it.
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.
