Usage: configure [options]
Options: [defaults in brackets after descriptions]
--enable-libopencore-amrwb enable AMR-WB decoding via libopencore-amrwb [no]
--enable-libopencv enable video filtering via libopencv [no]
--enable-libopenjpeg enable JPEG 2000 de/encoding via OpenJPEG [no]
+ --enable-libopus enable Opus decoding via libopus [no]
--enable-libpulse enable Pulseaudio input via libpulse [no]
--enable-librtmp enable RTMP[E] support via librtmp [no]
--enable-libschroedinger enable Dirac de/encoding via libschroedinger [no]
--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]
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-mmi disable MMI optimizations
--disable-neon disable NEON optimizations
--disable-vis disable VIS optimizations
+ --disable-inline-asm disable use of inline assembler
--disable-yasm disable use of yasm assembler
Developer options (useful when working on Libav itself):
include the log this produces with your report.
