Summary of the bug:
Rasperry Pi's cpu doesnt support NEON. OS: Raspbian GNU/Linux 7 (wheezy)
ffmpeg's ./configure fails with error in log when --enable-libx265 is on:
{{{
/disk2/ffmpeg_build/lib/libx265.so: undefined reference to
`x265_cpu_neon_test'
/disk2/ffmpeg_build/lib/libx265.so: undefined reference to
`x265_cpu_fast_neon_mrc_test'
collect2: ld returned 1 exit status
ERROR: x265 not found using pkg-config
}}}
How have i built x265:
{{{
cd /disk2/ffmpeg_sources
hg --time clone https://bitbucket.org/multicoreware/x265
cd x265/build/linux
./make-Makefiles.bash
make
make install
}}}
Here is config of ffmpeg:
{{{
cd /disk2/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
PATH="/disk2/fbin:$PATH"
PKG_CONFIG_PATH="/disk2/ffmpeg_build/lib/pkgconfig" ./configure \
--prefix="/disk2/ffmpeg_build" \
--extra-cflags="-I/disk2/ffmpeg_build/include" \
--extra-ldflags="-L/disk2/ffmpeg_build/lib" \
--bindir="/disk2/fbin" \
--enable-gpl \
--enable-libass \
--enable-libfdk-aac \
--enable-libfreetype \
--enable-libmp3lame \
--enable-libopus \
--enable-libtheora \
--enable-libvorbis \
--enable-libvpx \
--enable-libx264 \
--enable-libx265 \
--enable-libv4l2 \
--disable-neon --enable-vfp \
--enable-nonfree
}}}
a configure, a make and an ffmpeg work fine without libx265 integration
