--target-os=OS compiler targets OS [$target_os]
--target-exec=CMD command to run executables on target
--target-path=DIR path to view of build directory on target
+ --toolchain=NAME set tool defaults according to NAME
--nm=NM use nm tool
--ar=AR use archive tool AR [$ar_default]
--as=AS use assembler AS [$as_default]
--ld=LD use linker LD
--host-cc=HOSTCC use host C compiler HOSTCC

--disable-safe-bitstream-reader
disable buffer boundary checking in bitreaders
(faster, but may crash)
--enable-memalign-hack emulate memalign, interferes with memory debuggers
+ --enable-lto use link-time optimization
Optimization options (experts only):
--disable-asm disable all assembler optimizations
--disable-amd3dnow disable 3DNow! optimizations
--disable-amd3dnowext disable 3DNow! extended optimizations
--disable-mmx disable MMX optimizations
- --disable-mmx2 disable MMX2 optimizations
+ --disable-mmxext disable MMXEXT optimizations

Developer options (useful when working on Libav itself):
\$LIBAV_SAMPLES at make invocation time.
--enable-xmm-clobber-test check XMM registers for clobbering (Win64-only;
should be used only for debugging purposes)
+ --enable-random randomly enable/disable components
+ --disable-random
+ --enable-random=LIST randomly enable/disable specific components or
+ --disable-random=LIST component groups. LIST is a comma-separated list
+ of NAME[:PROB] entries where NAME is a component
+ (group) and PROB the probability associated with
+ NAME (default 0.5).
+ --random-seed=VALUE seed value for --enable/disable-random
