duplication . YUV transformations now use the new module API ; now only the vout and interface still depend on the old plugin API . changed TestMMX to TestCPU because we will be able to test for other specific extensions (3DNow, SSE) for the forthcoming IDCT we'll borrow to mpeg2dec (as usual :P) . don't show "hiding module" messages anymore except in debug mode . swapped C IDCT and Classic IDCT scores since the classic one seems to be faster ; anyway you should use the MMX one . fixed a Makefile bug under BeOS . tried to fix the cpuid code so that it compiles under BeOS (Polux, can you test it when you have time ?)
