(还有上传是的哪个效果,进度条如何作的?)或者给我个参考地址什 ... 环境redhat as41。首先获取ffmpeg很多人找不到怎么下载,其实之前ffmpeg可以通过cvs下载不过最近他已经换成了更加强大的svn如何使用SVN我这里不再介绍网上还有大量的安装和使用的文章可以借鉴这里简单罗列几个SVN辅助的软件SubVersion从
http://subversion.tigris.org/ 下载支持linux我们这里就装这个TortoiseSVN从
http://tortoisesvn.tigris.org/ 下载是很不错的SVN客户端程序为windows外壳程序集成到windows资源管理器和文件管理系统的Subversion客户端用起来很方便commit动作变得就像Winrar右键压缩一样方便。ok那我们先装subversion记住最好之前装过apr和apr-util在apache.org网站能下到wget http://subversion.tigris.org/downloads/subversion-1.3.2.tar.gztar zvxf subversion-1.3.2.tar.gzcd subversion-1.3.2./configure --with-apr/usr/local/apr-httpd --with-apr-util/usr/local/apr-util-httpd/makemake install到此我们就可以通过svn命令获取最新的ffmpeg了svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg你会发现在你所在的目录自动出现一个ffmpeg的目录就是你下载的源代码。我们还不能这么快编译ffmpeg应该如果要让ffmpeg支持更多格式的转换还需做一些前期工作2.支持mp3linux当然是lame下载解压cd lame-3.96.1./configure --enable-shared --prefix/usr这里推荐尽量装在/usr下默认是装在/usr/local下。这样ffmpeg编译都能顺利的找到库文件3.支持Ogg Vorbis:as4自带相应的rpm包你可以安装一下如下rpm包libvorbis, libvorbis-devel,libogg, libogg-devel4.支持xvid x264现在最流行的两种高质量的压缩格式xvid的编译安装wget http://downloads.xvid.org/downloads/xvidcore-1.1.0.tar.gztar zvxf xvidcore-1.1.0.tar.gz./configure --prefix/usrmakemake installx264的获取同样是采用svn方式看来svn取代cvs不远了svn co svn://svn.videolan.org/x264/trunk x264cd x264./configure --prefix/usr --enable-sharedmakemake install5.AC3和dts编码的支持as4系统似乎已经支持ac3编码编译的时候只要加--enable-a52 --enable-gpl参数就行libdts编译参数./configure --prefix/usrmakemake install6.mpg4 aac格式支持由于服务器还针对手机用户服务所以类似aacmpg4铃声格式的支持我们也得做。这里我们安装faad2和faac就行下载请到
http://www.audiocoding.com/modules/mydownloads/FAAD2的编译cd faad2autoreconf -vif./configure --prefix/usr --with-mp4v2 --enable-sharedmakemake installfaac的编译cd faacchmod x bootstrap./bootstrap./configure --prefix/usr --with-mp4v2 --enable-sharedmakemake install7.支持3gp格式这也是现在好多手机支持的格式因为手机用户是我们的主要用户所以也得支持编译编译的时候加上--enable-amr_nb --enable-amr_wb参数就行根据编译系统的提示所以我们得下载一些编译3gp所需得文件。wget http://www.3gpp.org/ftp/Specs/ar ... 6.204/26204-510.zip解压以后把里面的文件都拷贝到libavcodec/amrwb_floatwget http://www.3gpp.org/ftp/Specs/ar ... 6.104/26104-510.zip解压以后把里面的文件都拷贝到libavcodec/amr_float好了基本ffmpeg支持的格式我们基本都做好前期准备了下面是ffmpeg的编译./configure --prefix/usr --enable-gpl --enable-shared --enable-mp3lame --enable-amr_nb --enable-amr_wb --enable-amr_if2 --enable-libogg --enable-vorbis --enable-xvid --enable-a52 --enable-a52bin --enable-faadbin --enable-dts --enable-pp --enable-faad --enable-faac --enable-x264 --enable-pthreads --disable-ffserver --disable-ffplaymakemake install补充1关于3gp的编译如果大家要编译--enable-amr_nb-fixed那就不能跟--enable-amr_nb同时编译我不大清楚这两者到底有什么区别似乎fixed是修正版管他呢编译的方法wget http://www.3gpp.org/ftp/Specs/ar ... 6.073/26073-510.zip解压以后把里面的文件都拷贝到libavcodec/amr目录下修改libavcodec/amr/makefile 找到CFLAGS -Wall -pedantic-errors -I. $(CFLAGS_$(MODE)) -D$(VAD) 换成CFLAGS -Wall -I. $(CFLAGS_$(MODE)) -D$(VAD) -DMMS_IO整体编译参数就是./configure --prefix/usr --enable-gpl --enable-shared --enable-mp3lame --enable-amr_nb-fixed --enable-amr_wb --enable-amr_if2 --enable-libogg --enable-vorbis --enable-xvid --enable-a52 --enable-a52bin --enable-dts --enable-pp --enable-faad --enable-faadbin --enable-faac --enable-x264 --enable-pthreads --disable-ffserver --disable-ffplaymakemake install补充2有朋友说在当在cpu是x86的情况下不能编译过去我这里没发生过这情况如果你真编译不过去可以试着加上cpucpuok,一个强大的ffmpeg编译好了不过目前管方的ffmpeg还不支持wma9和rmvb不过网上有很多解决方法大家去自己找找。关于进度条的问题,我一直都无法解决.按道理新浪也不可能100%获取真实进度的吧?如果模拟的话就一大堆了,我这里提供一UPU的类用的SOCKET协议.[php]?php/*** UGiA PHP UPLOADER V0.2** Copyright 2005 legend
