It seems like we atleast also need to pass --target-os=linux, otherwise
configure fails:
Configuring included Libav instance with args --prefix=/usr
--disable-ffserver --disable-ffplay --disable-ffmpeg --disable-ffprobe
--enable-static --enable-pic --disable-encoder=flac
--disable-decoder=cavs --disable-protocols --disable-devices
--disable-network --disable-hwaccels --disable-filters --disable-doc
--enable-optimizations --enable-postproc --enable-gpl
--enable-cross-compile --target-os=linux-uclibcgnueabi --arch=arm
--cross-prefix=arm-buildroot-linux-uclibcgnueabi-
--cross-prefix=/home/peko/source/buildroot/output/host/usr/bin/arm-linux-
Unknown OS 'linux-uclibcgnueabi'.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
libav-user at libav.org mailing list or IRC #libav on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
config.status: error: Failed to configure embedded Libav tree
But what about all the CPU optimization flags we have in ffmpeg? Don't
we need to reproduce those as well here?
