nano pi neo2 上Ubuntu-core自行编译ffmpeg 动态so库   使用Ubuntu 16.04



环境Ubuntu 16 .04
nano pi neo 2 linux4.11.2 BSP 
工具链gcc-linaro-aarch64.tar.xz [4.9]

aarch64-linux-gnu-gcc -v

Thread model: posix
gcc version 4.9.3 20150113 (prerelease) (Linaro GCC 4.9-2015.01-3) 

源文件

alsa-lib-1.1.5.tar.bz2

ffmpeg-3.4.tar.bz2

last_x264.tar.bz2

lame-3.100.tar.gz

编译好的

http://download.csdn.net/download/aexisun/10139439






一.ubuntu 16.04 编译x264

 


1.解压配置

aaa@qq.com:~/nanopineo2$

aaa@qq.com:~/nanopineo2$

aaa@qq.com:~/nanopineo2$ tar xf last_x264.tar.bz2

aaa@qq.com:~/nanopineo2$ cd x264-snapshot-20171128-2245/

aaa@qq.com:~/nanopineo2/x264-snapshot-20171128-2245$ ./configure --host=aarch64-linux-gnu --prefix=/x264-h5 --enable-shared --disable-asm

2.修改文件 编译工具

aaa@qq.com:~/nanopineo2/x264-snapshot-20171128-2245$ vim config.mak

 

SYS_ARCH=ARM

SYS=LINUX
CC=aarch64-linux-gnu-gcc
CFLAGS=-Wno-maybe-uninitialized -Wshadow -O3 -ffast-math  -Wall -I. -I$(SRCPATH) -std=gnu99 -D_GNU_SOURCE -fPIC -fomit-frame-pointer -fno-tree-vectorize
COMPILER=GNU
COMPILER_STYLE=GNU
DEPMM=-MM -g0
DEPMT=-MT
LD=aarch64-linux-gnu-gcc -o
LDFLAGS= -lm -lpthread -ldl
LIBX264=libx264.a
AR=aarch64-linux-gnu-ar rc
RANLIB=aarch64-linux-gnu-ranlib
STRIP=strip

INSTALL=install


3.编译 install

make

make install


文件都在/x264-h5文件夹下le

 

二.编译liblamemp3 ffmpeg 所需的编码器

 

aaa@qq.com:~/nanopineo2$

aaa@qq.com:~/nanopineo2$

aaa@qq.com:~/nanopineo2$

aaa@qq.com:~/nanopineo2$

aaa@qq.com:~/nanopineo2$ tar xf lame-3.100.tar.gz

aaa@qq.com:~/nanopineo2$ cd lame-3.100/

aaa@qq.com:~/nanopineo2/lame-3.100$

aaa@qq.com:~/nanopineo2/lame-3.100$

aaa@qq.com:~/nanopineo2/lame-3.100$

aaa@qq.com:~/nanopineo2/lame-3.100$ ./configure --host=aarch64-linux-gnu --prefix=/lame-h5 --enable-shared --disable-static

aaa@qq.com:/home/sun/nanopineo2/lame-3.100#

make -j4

aaa@qq.com:/home/sun/nanopineo2/lame-3.100#

make install

 

 


文件都在/lame-h5文件夹下了

 

三.nano pi neo2 的Ubuntu core 缺少libasound.so文件

导致ffmpeg的alsa设备不能编译.

所以需要手动编译alsa-lib到工具链和板子上

 

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2# tar xf alsa-lib-1.1.5.tar.bz2

aaa@qq.com:/home/sun/nanopineo2# cd alsa-lib-1.1.5

aaa@qq.com:/home/sun/nanopineo2/alsa-lib-1.1.5# ./configure --host=aarch64-linux-gnu --prefix=/alsa-h5 --enable-shared --disable-static

aaa@qq.com:/home/sun/nanopineo2/alsa-lib-1.1.5# make -j4

aaa@qq.com:/home/sun/nanopineo2/alsa-lib-1.1.5# make install

 

文件都在/lalsa-h5文件夹下了

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2# cp -rf /alsa-h5/lib* gcc-linaro-4.9-2015.02-3-x86_64_aarch64-linux-gnu/lib/gcc/aarch64-linux-gnu/4.9.3/

aaa@qq.com:/home/sun/nanopineo2# cp -rf /alsa-h5/include/* gcc-linaro-4.9-2015.02-3-x86_64_aarch64-linux-gnu/lib/gcc/aarch64-linux-gnu/4.9.3/include

 

编译ffmpeg前 需要把lasa/lib include 下的文件考到编译工具下,否则不能识别alsa设备
四.编译ffmpeg

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2#

aaa@qq.com:/home/sun/nanopineo2# tar xf ffmpeg-3.4.tar.bz2

aaa@qq.com:/home/sun/nanopineo2# cd ffmpeg-3.4

aaa@qq.com:/home/sun/nanopineo2/ffmpeg-3.4# ./configure --cross-prefix=aarch64-linux-gnu- --enable-cross-compile --target-os=linux

--cc=aarch64-linux-gnu-gcc --arch=arm64 --prefix=/ffmpeg-h5 --enable-shared --disable-static --enable-gpl --enable-nonfree --enable-libx264

--enable-ffmpeg --disable-ffplay --enable-ffserver --enable-swscale --enable-pthreads  --enable-libmp3lame  --disable-stripping

--extra-cflags=-I/x264-h5/include --extra-ldflags=-L/x264-h5/lib --extra-cflags=-I/lame-h5/include --extra-ldflags=-L/lame-h5/lib

然后看下配置的结果有没有alsa

Enabled bsfs:

aac_adtstoasc   imx_dump_header      null

chomp   mjpeg2jpeg      remove_extradata

dca_core   mjpega_dump_header      text2movsub

dump_extradata   mov2textsub      vp9_raw_reorder

extract_extradata   mp3_header_decompress      vp9_superframe

h264_mp4toannexb   mpeg4_unpack_bframes      vp9_superframe_split

hevc_mp4toannexb   noise

 

Enabled indevs:alsa   lavfi      v4l2

fbdev   oss

 

Enabled outdevs:alsa   oss      v4l2

fbdev

Creating configuration files ...

 

WARNING: aarch64-linux-gnu-pkg-config not found, library detection may fail.

WARNING: using libx264 without pkg-config

aaa@qq.com:/home/sun/nanopineo2/ffmpeg-3.4#

 


make -j4
make install

出现这个错误 C compiler test failed
arch=arm64折腾半天

 

 

五.复制所需的文件

把

lame-h5

x264-h5

ffmpeg-h5

alsa-h5

 的lib include目录下的   都复制到nano板子/usr/lib /usr/include/

单独的复制ffmpeg-h5的bin目录下的文件  到nano板子的/usr/bin下[ffmpeg ffplay之类的]

aaa@qq.com:/home/pi# tar xf ffmpeg-h5.tar

aaa@qq.com:/home/pi# tar xf lame-h5.tar

aaa@qq.com:/home/pi# tar xf x264-h5.tar

aaa@qq.com:/home/pi# tar xf alsa-h5.tar

 

 

aaa@qq.com:/home/pi#

aaa@qq.com:/home/pi#

aaa@qq.com:/home/pi#

aaa@qq.com:/home/pi#

aaa@qq.com:/home/pi#

aaa@qq.com:/home/pi#

aaa@qq.com:/home/pi# cd /alsa-h5/

aaa@qq.com:/alsa-h5#

aaa@qq.com:/alsa-h5#

aaa@qq.com:/alsa-h5#

aaa@qq.com:/alsa-h5#

aaa@qq.com:/alsa-h5#

aaa@qq.com:/alsa-h5# cp -rf lib/* /usr/lib/;cp -rf include/ /usr/include/

aaa@qq.com:/alsa-h5# cd ../x264-h5/

aaa@qq.com:/x264-h5# cp -rf lib/* /usr/lib/;cp -rf include/ /usr/include/

aaa@qq.com:/x264-h5# cd ../lame-h5/

aaa@qq.com:/lame-h5# cp -rf lib/* /usr/lib/;cp -rf include/ /usr/include/

aaa@qq.com:/lame-h5# cd ../ffmpeg-h5/

aaa@qq.com:/ffmpeg-h5# cp -rf lib/* /usr/lib/;cp -rf include/ /usr/include/

aaa@qq.com:/ffmpeg-h5# cp -rf bin/* /usr/bin/

aaa@qq.com:/ffmpeg-h5#

aaa@qq.com:/ffmpeg-h5#

 

如果需要用ffmpeg的C库开发 还有把上面文件复制到编译工具链里面.就不需要bin目录了

gcc-linaro-4.9-2015.02-3-x86_64_aarch64-linux-gnu/lib/gcc/aarch64-linux-gnu/4.9.3/

这个目录是编译器的目录

 

六.测试下
