--mandir=DIR install man page in DIR [PREFIX/share/man]
--enable-rpath use rpath to allow installing libraries in paths
not part of the dynamic linker search path
+ use rpath when linking programs [USE WITH CARE]
Licensing options:
--enable-gpl allow use of GPL code, the resulting libs
native MPEG-4/Xvid encoder exists [no]
--enable-libzmq enable message passing via libzmq [no]
--enable-libzvbi enable teletext support via libzvbi [no]
+ --disable-lzma disable lzma [autodetect]
--enable-decklink enable Blackmagick DeckLink output [no]
--enable-openal enable OpenAL 1.1 capture support [no]
--enable-opencl enable OpenCL code
disable buffer boundary checking in bitreaders
(faster, but may crash)
--enable-memalign-hack emulate memalign, interferes with memory debuggers
- --enable-sram allow use of on-chip SRAM
--sws-max-filter-size=N the max filter size swscale uses [$sws_max_filter_size_default]
