--enable-sram allow use of on-chip SRAM
--disable-symver disable symbol versioning
--disable-fastdiv disable table-based division
--enable-hardcoded-tables use hardcoded tables instead of runtime generation
--disable-safe-bitstream-reader
disable buffer boundary checking in bitreaders
(faster, but may crash)
--enable-memalign-hack emulate memalign, interferes with memory debuggers

Optimization options (experts only):
--disable-asm disable all assembler optimizations
--disable-altivec disable AltiVec optimizations
--disable-amd3dnow disable 3DNow! optimizations
--disable-amd3dnowext disable 3DNow! extended optimizations
--disable-mmx disable MMX optimizations
--disable-mmx2 disable MMX2 optimizations
--disable-sse disable SSE optimizations
--disable-ssse3 disable SSSE3 optimizations
--disable-avx disable AVX optimizations
--disable-armv5te disable armv5te optimizations
--disable-armv6 disable armv6 optimizations
--disable-armv6t2 disable armv6t2 optimizations
--disable-armvfp disable ARM VFP optimizations
--disable-mmi disable MMI optimizations
--disable-neon disable NEON optimizations
--disable-vis disable VIS optimizations
--disable-yasm disable use of yasm assembler
--malloc-prefix=PFX prefix malloc and related names with PFX

Developer options (useful when working on FFmpeg itself):
--disable-debug disable debugging symbols
--enable-debug=LEVEL set the debug level [$debuglevel]
--disable-optimizations disable compiler optimizations
--enable-extra-warnings enable more compiler warnings
--disable-stripping disable stripping of executables and shared libraries
--assert-level=level 0(default), 1 or 2, amount of assertion testing,
2 causes a slowdown at runtime.
--samples=PATH location of test samples for FATE
