# 一、           编译安装VLC #

使用vlc-1.0.5.tar.bz2 +　live555-2010.01.tar.gz

exportMYDIR=/root/lf

将live555-2010.01.tar.gz和vlc-1.0.5.tar.bz2放置在$MYDIR下

cd$MYDIR

## (一)         编译liveMedia ##

tar xvfzlive555-2010.01.tar.gz

cd live

./genMakefileslinux

make

## (二)         安装libdvbpsi ##

rpm -hiv libdvbpsi-0.1.7-1.el4.rf.i386.rpm

rpm -hiv libdvbpsi-devel-0.1.7-1.el4.rf.i386.rpm

需要什么rpm可到[http://apt.sw.be/redhat/el4/en/i386/rpmforge/RPMS/][http_apt.sw.be_redhat_el4_en_i386_rpmforge_RPMS]中下载

## (三)         编译VLC ##

### 1.   configure ###

./configure--prefix=/usr --enable-debug --disable-avcodec --disable-hal --disable-avformat--disable-swscale --disable-a52 --disable-x11 --disable-sdl --disable-fribidi--disable-dbus --disable-libgcrypt --disable-gnutls --disable-remoteosd  --disable-skins2 --disable-qt4  --disable-libxml2  --disable-lua --disable-xcb --disable-alsa--disable-v4l2  --disable-qt --enable-run-as-root**--enable-live555--with-live555-tree=$MYDIR/live** \--disable-mad --disable-postproc**--enable-dvbpsi** \--enable-x264

### 2.   make ###

### 3.   出现错误error: syntax error before "vlc\_spinlock\_t"： ###

../include/vlc\_threads.h:240:error: syntax error before "vlc\_spinlock\_t"

……

make\[4\]:\*\*\* \[control/libvlc\_la-vlm.lo\] Error 1

make\[4\]:Leaving directory \`/root/lf/vlc-1.0.5/src'

make\[3\]:\*\*\* \[all-recursive\] Error 1

make\[3\]:Leaving directory \`/root/lf/vlc-1.0.5/src'

make\[2\]:\*\*\* \[all\] Error 2

make\[2\]:Leaving directory \`/root/lf/vlc-1.0.5/src'

make\[1\]:\*\*\* \[all-recursive\] Error 1

make\[1\]:Leaving directory \`/root/lf/vlc-1.0.5'

make:\*\*\* \[all\] Error 2

通过以下命令解决：

sed -e's/define\\s\*\_POSIX\_SPIN\_LOCKS\\s\*/define \_POSIX\_SPIN\_LOCKS -1 \\/\\/ wrong: /g' -i/usr/include/bits/posix\_opt.h

### 4.   重试make出现error:\`AFS\_SUPER\_MAGIC' undeclared： ###

file.c:52:28:linux/magic.h: No such file or directory

file.c:In function \`IsRemote':

file.c:141:error: \`AFS\_SUPER\_MAGIC' undeclared (first use in this function)

file.c:141:error: (Each undeclared identifier is reported only once

file.c:141:error: for each function it appears in.)

file.c:142:error: \`CODA\_SUPER\_MAGIC' undeclared (first use in this function)

file.c:143:error: \`NCP\_SUPER\_MAGIC' undeclared (first use in this function)

file.c:144:error: \`NFS\_SUPER\_MAGIC' undeclared (first use in this function)

file.c:145:error: \`SMB\_SUPER\_MAGIC' undeclared (first use in this function)

make\[5\]:\*\*\* \[libaccess\_file\_plugin\_la-file.lo\] Error 1

make\[5\]:Leaving directory \`/root/lf/vlc-1.0.5/modules/access'

make\[4\]:\*\*\* \[all-recursive\] Error 1

make\[4\]:Leaving directory \`/root/lf/vlc-1.0.5/modules/access'

make\[3\]:\*\*\* \[all\] Error 2

make\[3\]:Leaving directory \`/root/lf/vlc-1.0.5/modules/access'

make\[2\]:\*\*\* \[all-recursive\] Error 1

make\[2\]:Leaving directory \`/root/lf/vlc-1.0.5/modules'

make\[1\]:\*\*\* \[all-recursive\] Error 1

make\[1\]:Leaving directory \`/root/lf/vlc-1.0.5'

make:\*\*\* \[all\] Error 2

将下面的magic.h文件复制到/usr/include/linux/目录下

### 5.   make install ###

### 6.   检查 ###

vlc -l | grep access\_output

access\_output\_udp     UDP stream output

**access\_output\_http    HTTP stream output**

access\_output\_file    File stream output

access\_output\_dummy   Dummy stream output

access\_output\_rtmp    RTMP stream output

vlc -l | grep dvbpsi

**mux\_ts                TS muxer (libdvbpsi)**

## (四)         进行RTSP To TS转码： ##

Ø        不经视音频重编码的直接转码：

vlc rtsp://172.17.0.219:8554/1--sout  '\#standard\{access=http, mux=ts,dst=**172.17.0.100**:**1234**\}'

注：黑体部分为本机ＩＰ和端口，不能是127.0.0.1

vlc rtsp://172.17.0.219:8554/1--sout '\#duplicate\{dst="std\{access=udp, mux=ts, dst=172.17.1.116:1234\}"\}'

vlcrtsp://172.17.0.219:8554/1 --sout '\#duplicate\{dst="std\{access=http, mux=ts,dst=172.17.0.100:1234\}"\}'

# 二、           视音频重编码的VLC编译安装 #

## (一)         需要编译安装ffmpeg ##

./configure--prefix=/usr  --enable-libfaac--enable-libx264 --enable-pthreads --disable-ffserver --disable-ffplay--enable-gpl  --enable-nonfree

\[root@localhostffmpeg-0.6.7\]\# make

common.mak:28:\*\*\* unterminated call to function \`foreach': missing \`)'.  Stop.

出现上面错误需要更新Make版本，使用make-3.81.tar.gz

./configure--prefix=/usr;make;make install

In fileincluded from libavdevice/v4l.c:33:

/usr/include/linux/videodev.h:56:error: syntax error before "ulong"

/usr/include/linux/videodev.h:72:error: syntax error before '\}' token

编辑/usr/include/linux/videodev.h第56行，把ulong改为 unsigned long

## (二)         编译VLC ##

./configure--prefix=/usr --enable-debug**--enable-avcodec** \--disable-hal --disable-avformat--disable-swscale --disable-a52 --disable-x11 --disable-sdl --disable-fribidi--disable-dbus --disable-libgcrypt --disable-gnutls --disable-remoteosd  --disable-skins2 --disable-qt4  --disable-libxml2  --disable-lua --disable-xcb --disable-alsa--disable-v4l2  --disable-qt --enable-run-as-root**--enable-live555--with-live555-tree=$MYDIR/live** \--disable-mad --disable-postproc**--enable-dvbpsi** \--enable-x264

没有**--enable-avcodec**运行VLC转码会出现"cannot find video decoder"的错误。

## (三)         进行RTSP To TS转码： ##

vlctcp://172.17.0.199:7799 --sout'\#duplicate\{dst="transcode\{venc=x264\{profile=baseline\},vcodec=h264,acodec=mpga,vb=644,ab=56\}:std\{access=udp,mux=ts,dst=172.17.0.219:1234\}"\}'

** **

使用VLC转时，不要激活转码

可正常工作的选项：

:sout=\#http\{mux=ts,dst=:8080/1\} :sout-keep

:sout=\#udp\{mux=ts,dst=172.17.1.116:1234\} :sout-keep

./configure --prefix=/usr  --enable-libfaac --enable-libx264--enable-pthreads --disable-ffserver --disable-ffplay --enable-gpl  --enable-nonfree
