--enable-sram allow use of on-chip SRAM
--enable-thumb compile for Thumb instruction set
--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
\$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
