--arch=ARCH select architecture [$arch]
--cpu=CPU select the minimum required CPU (affects
instruction selection, may crash on older CPUs)
- --enable-powerpc-perf enable performance report on PPC
- (requires enabling PMC)
--disable-asm disable all assembler optimizations
--disable-altivec disable AltiVec optimizations
--disable-amd3dnow disable 3DNow! optimizations
Developer options (useful when working on FFmpeg itself):
--disable-debug disable debugging symbols
--enable-debug=LEVEL set the debug level [$debuglevel]
- --enable-gprof enable profiling with gprof [$gprof]
--disable-optimizations disable compiler optimizations
--enable-extra-warnings enable more compiler warnings
--disable-stripping disable stripping of executables and shared libraries
