follow ..build static linked ffmpeg.

ref:

• build static ffmpeg

就 download libx264 跟 ffmpeg 的 source..
然後 config 要讓 ffmpeg 找到

pi@ubuntu:~/ffempg-static/libx264-git$ ./configure --prefix=/home/pi/ffmpeg-static/workspace --enable-static --enable-pic
platform:      AARCH64
byte order:    little-endian
system:        LINUX
cli:           yes
libx264:       internal
shared:        no
static:        yes
asm:           yes
interlaced:    yes
avs:           avxsynth
lavf:          no
ffms:          no
mp4:           no
gpl:           yes
thread:        posix
opencl:        yes
filters:       crop select_every 
debug:         no
gprof:         no
strip:         no
PIC:           yes
bit depth:     8
chroma format: all

You can run 'make' or 'make fprofiled' now.

make 完後..install

pi@ubuntu:~/ffempg-static/libx264-git$ make install
install -d /home/pi/ffmpeg-static/workspace/bin
install x264 /home/pi/ffmpeg-static/workspace/bin
install -d /home/pi/ffmpeg-static/workspace/include
install -d /home/pi/ffmpeg-static/workspace/lib
install -d /home/pi/ffmpeg-static/workspace/lib/pkgconfig
install -m 644 ./x264.h /home/pi/ffmpeg-static/workspace/include
install -m 644 x264_config.h /home/pi/ffmpeg-static/workspace/include
install -m 644 x264.pc /home/pi/ffmpeg-static/workspace/lib/pkgconfig
install -m 644 libx264.a /home/pi/ffmpeg-static/workspace/lib
ranlib /home/pi/ffmpeg-static/workspace/lib/libx264.a

然後是 ffmpeg..

./configure --prefix=/home/pi/ffmpeg-static/workspace \
--extra-version=patrickz --disable-debug --disable-shared --enable-static \
--disable-doc --enable-gpl  --enable-nonfree --enable-version3 \
--pkg-config-flags="--static" \
--enable-libx264 \
--enable-filters \
--extra-cflags="-I--prefix=/home/pi/ffmpeg-static/workspace/include -static" \
--extra-ldflags="-L--prefix=/home/pi/ffmpeg-static/workspace/lib -static"

接著來 enable neon 看看...
