--disable-mipsdspr2 disable MIPS DSP ASE R2 optimizations
--disable-msa disable MSA optimizations
--disable-mipsfpu disable floating point MIPS optimizations
+ --disable-loongson3 disable Loongson-3 SIMD optimizations
--disable-fast-unaligned consider unaligned accesses slow
Developer options (useful when working on FFmpeg itself):
(group) and PROB the probability associated with
NAME (default 0.5).
--random-seed=VALUE seed value for --enable/disable-random
+ --disable-valgrind-backtrace do not print a backtrace under Valgrind
+ (only applies to --disable-optimizations builds)
NOTE: Object files are built at the place where configure is launched.
