为 Raspberry Pi 编译 Xuggler 的指南 [英] Guide to compile Xuggler for Raspberry Pi

问题描述

有人可以详细写一篇关于如何为 Raspberry Pi 编译 Xuggler 的文章吗?

Can someone post a detailed write up, on how to compile Xuggler for Raspberry Pi?

推荐答案

经过大约 5 天的工作，我将以下指南用于为 Raspberry Pi 编译 xuggler(所需时间:8 小时):

After working on for about 5 days , I am putting the following guide to compile xuggler for Raspberry Pi (Time required : 8 hrs):

先决条件:

1. 具有 512 MB RAM 的 Raspberry Pi Model B+(任何小于此的型号都不会为您提供已编译的二进制文件，并且会在编译期间卡住)
2. Raspbian 安装在 SD 卡上(超过 4GB SD 卡即可)

步骤:

1. 切换到root"用户.

1. Switch to 'root' user.

从基本 xuggler 构建页面安装依赖项 (http://www.xuggle.com/xuggler/build) 标记为必需"

From the Basic xuggler build page install the dependencies (http://www.xuggle.com/xuggler/build) labeled as 'Required'

创建和导出变量如下(制作相关目录)

Create and export variables as follows (Make the relevant directories)

export XUGGLE_HOME=/home/pi/Downloads/xuggler    
export PATH=$XUGGLE_HOME/bin:$PATH    
export LD_LIBRARY_PATH=$XUGGLE_HOME/lib:$LD_LIBRARY_PATH

创建以下链接:

Create the following link:

sudo ln -s /usr/bin/make /usr/bin/gmake

如果您支持任何类型的网络代理，那么也设置以下变量:

If you are behind any kind of web proxy then set the following variables too:

export http_proxy='proxy-url:port'    
export https_proxy='proxy-url:port'    
export ftp_proxy='proxy-url:port'

现在移动到以下目录:

Now move to the following directory:

cd /home/pi/Downloads/

从这里下载 xuggler 代码(https://github.com/artclarke/xuggle-xuggler):

git clone https://github.com/artclarke/xuggle-xuggler.git

代码将下载到名为xuggle-xuggler"的目录

The code would be downloaded in the directory named 'xuggle-xuggler'

移动到目录 'xuggle-xuggler'

Move inside the directory 'xuggle-xuggler'

如果您在代理后面，请在文件build.xml"中添加以下行，就在文件中的property"xml标签下方:

If you are behind a proxy add the following line in the file 'build.xml', just below the 'property' xml tags in the file:

<setproxy proxyhost="proxy-url" proxyport="port"/>

现在编辑文件captive/libspeex/csrc/configure"如下:

Now edit the file 'captive/libspeex/csrc/configure' as follows:

来自:

CFLAGS="$CFLAGS -O3 -msse"

致:

CFLAGS="$CFLAGS -O3"

和

来自:

if test "$has_sse" = yes; then
$as_echo "#define _USE_SSE /**/" >>confdefs.h
fi

致:

#if test "$has_sse" = yes; then
#$as_echo "#define _USE_SSE /**/" >>confdefs.h
#fi

有关详细信息，请参阅此.

Refer this for more info.

现在编辑文件captive/libspeex/csrc/configure.ac"如下:

Now edit the file ' captive/libspeex/csrc/configure.ac' as follows:

来自:

CFLAGS="$CFLAGS -O3 -msse"

致:

CFLAGS="$CFLAGS -O3"

还有

来自:

if test "$has_sse" = yes; then
 AC_DEFINE([_USE_SSE], , [Enable SSE support])
fi

致:

#if test "$has_sse" = yes; then
# AC_DEFINE([_USE_SSE], , [Enable SSE support])
#fi

有关详细信息，请参阅此.

Refer this for more info.

现在如 xuggler 高级构建链接 (http://www.xuggle.com/xuggler/advbuild)，启动命令:

Now as listed in the xuggler advance build link (http://www.xuggle.com/xuggler/advbuild), launch the command:

ant stage

该过程将在 libX264 编译时或编译过程中失败，要绕过它，请在现在生成的文件中添加以下编译开关，即编辑文件captive/libx264/incarcerate.in":

The process will fail at or during the compilation of libX264, to circumvent it, add the following compile switches in the now generated file i.e edit file 'captive/libx264/incarcerate.in' :

来自:

X264_OPTIONS="$X264_OPTIONS --enable-static"
X264_OPTIONS="$X264_OPTIONS --enable-pic"

致:

X264_OPTIONS="$X264_OPTIONS --disable-asm"
X264_OPTIONS="$X264_OPTIONS --enable-shared"
X264_OPTIONS="$X264_OPTIONS --enable-static"
X264_OPTIONS="$X264_OPTIONS --enable-pic"

现在运行以下命令(一一):

Now run following command(one by one only):

ant clobber
ant clean
ant stage

这次所有的编译步骤都会完成.

This time all the compile steps will go through.

运行安装命令:

ant install

xuggler 二进制文件将安装在第 3 步中定义的XUGGLE_HOME"位置.

The xuggler binaries would be installed at the location 'XUGGLE_HOME' as defined in step #3.

Java 二进制文件的 xuggler maven 存储库将位于/root/.m2/repository/xuggle/xuggle-xuggler"

The xuggler maven repository for java binaries would be located at '/root/.m2/repository/xuggle/xuggle-xuggler'

您还可以查看../xuggle-xuggler/dist"目录以检查所有本机和 Java 二进制文件，以供非 Maven 使用.

Also you can check out the '../xuggle-xuggler/dist' directory to check all the native and java binaries for your non-maven kind of use.

编译后的二进制文件在 Raspberry PI(Arch Linux、Raspbian)上运行良好.

The compiled binaries ran fine on Raspberry PI (Arch Linux, Raspbian).

如果您没有时间编译，请从 此处.

在使用我编译的java二进制文件之前，请确保在java类路径或shell终端中添加步骤#3中定义的变量.

Make sure to add the variables as defined in step #3 in java class path or shell terminal before using the java binaries compiled by me.
