A PowerPC-optimized build of LAME 3.100 with tmkk's patches for AltiVec, enhanced with additional G5 optimizations and build-system fixes. Intended for lovely Power Macs and not icky Intel Macs, which are better served by the mainline build. Maintained by Cameron Kaiser (firstname.lastname@example.org).
How to build (GNU
make from MacPorts strongly recommended):
- Have a 10.4 system with Xcode 2.5. (It may or may not work on 10.5 with Xcode 3. It probably doesn't work on 10.6. It will not work on 10.7+.)
- Clone it.
You will have a three-headed multi-architecture binary in
frontend/lame with versions for G3, G4 and G5 processors. The same binary runs on all systems. Do
gmake test for a quick test of functionality.
On my Quad G5 (2.5GHz), LAMEVMX achieves approximately 25x playback speed at peak.
