You can use the GAP package REPSN. The function "ConstituentsOfRepresentation" decomposes the given ordinary reducible representation to its irreducible constituents. You can contact me directly if you have any question about this package.

Subject: [GAP Forum] Decomposing direct products of reps into irreps
Suppose I take the direct product of two two-dimensional representations of D4...and then I want to decompose it as direct sum of irreducible representations of D4........
I need to do such decompositions quite often for my current project...
So I was wondering if GAP has anything built in to tackle the above task...
I searched the manual but came up with nought....
