The only complication was that I had to add namespaces to TestAudioMixer.cpp and TestAudioSegment.cpp to avoid multiple definitions of a few small helper functions like GetLowValue(). --HG-- rename : dom/media/compiledtest/TestAudioBuffers.cpp => dom/media/gtest/TestAudioBuffers.cpp rename : dom/media/compiledtest/TestAudioMixer.cpp => dom/media/gtest/TestAudioMixer.cpp rename : dom/media/compiledtest/TestAudioPacketizer.cpp => dom/media/gtest/TestAudioPacketizer.cpp rename : dom/media/compiledtest/TestAudioSegment.cpp => dom/media/gtest/TestAudioSegment.cpp extra : rebase_source : f42a1209b98a344c77e1245815eebc86a16866c0
