目前有很多视频剪辑合并工具,其功能很强大.但是用起来很麻烦,一段一段需要手动处理.为了弥补这个弊端利用
批处理文件完成全自动剪辑和合并的功能.效率灰常高哈哈 通过配置文件输入剪辑时间使用起来更加方便

1.安装wine
[xxx@localhost ~]$sudo yum install wine
You need to install cabextract first!
yum install wine cabextract
升级linux+wine中安装IE
http://www.tatanka.com.br/ies4linux/downloads/ies4linux-latest.tar.gz
在ies4linux-2.99.0.1/lib/install.sh 中修改corefonts下载地址
http://cdnetworks-kr-1.dl.sourceforge.net/project/corefonts/the%20fonts/final/andale32.exe
for font in $COREFONTS; do
#download "http://internap.dl.sourceforge.net/sourceforge/corefonts/$font"
download "http://cdnetworks-kr-1.dl.sourceforge.net/project/corefonts/the%20fonts/final/$font"
done
在install.sh 426行左右
subsection $MSG_CREATING_PREFIX
set_wine_prefix "$BASEDIR/ie1/"
wineprefixcreate &> /dev/null
clean_tmp
改为：
subsection $MSG_CREATING_PREFIX
set_wine_prefix "$BASEDIR/ie1/"
winepath &> /dev/null
clean_tmp
在functions.sh 242行左右
function create_wine_prefix {
if which wineprefixcreate &> /dev/null; then
( wineprefixcreate 2>&1 ) | debugPipe
else

}
改为：
function create_wine_prefix {
if which winepath &> /dev/null; then
( winepath 2>&1 ) | debugPipe
else
error $MSG_ERROR_NO_WINEPREFIXCREATE
fi
}
./ies4linux --no-gui --beta-install-ie7 --locale CN --install-corefonts
2.下载rar+迅雷deb版 for Linux 5.5 绿色版
http://dl-sh-ctc-2.pchome.net/0p/jh/rarlinux-4.2.0.tar.gz
解压到一个目录 运行 make install
http://dx.cr173.com//soft1/wine_thunder.rar 其他版本都运行不正常
Thunder.tar.gz 解压到 /home/xxx/.wine/drive_c/Program Files/Thunder
3.配置wine中文环境
/home/xxx/.wine/drive_c/windows 下创建chinese_env.reg文件
文件内容是
REGEDIT4
[KEY_LOCAL_MACHINE\\Software\\Microsoft\\Window NT\\CurrentVersion\FontSubstitutes]
"MS Shell Dlg"="SimSun.ttc,SimSun"
"MS Shell Dlg 2"="SimSun.ttc,SimSun"
SimSun.ttc字体文件拷贝到/home/xxx/.wine/drive_c/windows/Fonts
然后
[xxx@localhost ~]$cd /home/xxx/.wine/drive_c/windows
[xxx@localhost ~]$wine regedit.exe
在regedit菜单中选导入chinese_env.reg，退出wine.
[xxx@localhost ~]$export LANG=zh_CN.UTF-8
4.开始运行程序
[xxx@localhost ~]$wine filename 就可以运行中文界面的程序 这样可以运行大部分程序
5.运行迅雷5出现问题，比如暂停死机、暂停下载重新下载时从零开始下载的问题时，如下操作就可以
首先把迅雷5程序拷贝到/xxx/.ies4linux/ie6/drive_c/Program Files/下面
[xxx@localhost ~]$ie6
运行ie6，然后在打开菜单中选择迅雷5就可以运行，暂停死机的问题就解决了。
备注:ie6 运行比较正常,为了加快速度启动把主页改成about:blank，下次启动ie6时比较快
这个版本的ie7有些问题，有些功能都没有，Internet选项功能没有，如何修改主页呢？
文件->打开->regedit.exe 主页修改成 about:blank
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\Start Page
环境:Win系统
用liveusb-creator-3.11.7工具把Fedora-17-x86_64-Live-Desktop.iso文件写入U盘安装成功.
用liveusb-creator-3.11.7工具Fedora-17-i386-DVD.iso文件写入U盘,进行安装时写分区信息时出现如下错误提示
An unhandled exception has occurred.This is most likely a bug.
Pleas save a copy of the detailed exception and file a bug report.
Live-Desktop只是应用平台,没有开发平台.
解决方法:
当然最简单的是刻录DVD就可以,没有DVD光驱这么办呢?
环境:Fedora系统
df -h #查看U盘的设备名称 通常是 /dev/sdb1
umount U盘挂载目录 #如 /run/media/xxx/xxx 制作安装盘时不能挂载
su -c yum install livecd-tools
su -c livecd-iso-to-disk path_to/Fedora-17-i386-DVD.iso /dev/sdb1
备注:liveusb-creator-3.11.7工具有缺陷,只能用livecd-iso-to-disk命令,得出这个结果让我浪费了好多时间
STEP1.下载MinGW-full-20101119.7z 2010-11-19 63.6MB 解压到C:/MinGW下
http://sourceforge.net/projects/mplayer-ww/files/MinGW-full/
STEP2.下载源码
https://gitorious.org/mplayer-ww
下载的部分
A.patch for mplayer ww
B.x264 support pictiming in pmp files.
C.mplayer-ww
D.ffmpeg-ww
---------------------------------------
E.F.是VS2010编写的配置可视化程序可以忽略
E.meditor2 - Configure file editor for mplayer ww
F.dshownative - Direct Show Native Wrapper for mplayer
备注:git下载方法 Source tree -> Commint log -> Download master as tar.gz
STEP3.进行编译
A.下载的4个包都解压到/MinGW/home/
B.把mplayer-ww-mpatch的所有文件覆盖到mplayer-ww-mplayer-ww目录下
C.编译mplayer-ww-x264-pmp,该目录下的automk.sh自动编译
D.编译mplayer-ww-ffmpeg-ww,该目录下的automk.sh自动编译[编译时间较长]
E.编译mplayer-ww-mplayer-ww,该目录下的automk.sh自动编译
STEP4.运行测试
A.ffmpeg-ww\bin\*.dll 拷贝到mplayer-ww-mplayer-ww/release/
B.下载MPlayer-ww运行程序,最新Revision 35130 2012-08-31
http://sourceforge.net/projects/mplayer-ww/files/MPlayer_Release/
安装目录下的[*.ini meditor2.exe meditor.exe skin]拷贝到mplayer-ww-mplayer-ww/release/
运行mplayer.exe
安装VS2010之前安装了VS6，这是环境变量是
include=C:\Program Files\Microsoft Visual Studio\VC98\atl\include;C:\Program Files\Microsoft Visual Studio\VC98\mfc\include;C:\Program Files\Microsoft Visual Studio\VC98\include
lib=C:\Program Files\Microsoft Visual Studio\VC98\mfc\lib;C:\Program Files\Microsoft Visual Studio\VC98\lib

安装VS2010后，创建MFC工程，编译就出现
afxglobals.h(375): error C2143错误
这是因为include和lib目录有缺陷。
VS2010->Property Pages->VC++ Directories->Debug[Release]->
Microsoft.Cpp.Win32.user->Include and Library设置正确的路径。
VS2010之前的VC++ Directories目录是全局共享的。VS2010后VC++ Directories是每个工程单独设置，没有全局共享模式。
特别提示:默认VC++ Directories虽然没有设置全局的界面，但是通过
Microsoft.Cpp.Win32.user->这个操作可以修改默认的VC++ Directories设置。
修改方法
STEP1.修改环境
VS2010默认安装中Microsoft SDKsv7.0A,#include "SDKDDKVer.h"这个就在SDK中，配置时一定要SDK的目录。
C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat这个批处理是自动配置VS2010的环境变量
DevEnvDir=C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\
INCLUDE=C:\Program Files\Microsoft Visual Studio 10.0\VC\INCLUDE;C:\Program Files\Microsoft Visual Studio 10.0\VC\ATLMFC\INCLUDE;C:\Program Files\Microsoft SDKs\Windows\v7.0A\include;
LIB=C:\Program Files\Microsoft Visual Studio 10.0\VC\LIB;C:\Program Files\Microsoft Visual Studio 10.0\VC\ATLMFC\LIB;C:\Program Files\Microsoft SDKs\Windows\v7.0A\lib;
LIBPATH=C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319;C:\WINDOWS\Microsoft.NET\Framework\v3.5;C:\Program Files\Microsoft Visual Studio 10.0\VC\LIB;C:\Program Files\Microsoft Visual Studio 10.0\VC\ATLMFC\LIB;
WindowsSdkDir=C:\Program Files\Microsoft SDKs\Windows\v7.0A\
VSINSTALLDIR=C:\Program Files\Microsoft Visual Studio 10.0\
Path=C:\Program Files\Microsoft F#\v4.0\;C:\Program Files\Microsoft Visual Studio 10.0\VSTSDB\Deploy;C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\;C:\Program Files\Microsoft Visual Studio 10.0\VC\BIN;C:\Program Files\Microsoft Visual Studio 10.0\Common7\Tools;C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319;C:\WINDOWS\Microsoft.NET\Framework\v3.5;C:\Program Files\Microsoft Visual Studio 10.0\VC\VCPackages;C:\Program Files\HTML Help Workshop;C:\Program Files\Microsoft Visual Studio 10.0\Team Tools\Performance Tools;C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools;C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin;
SETP2.修改VC++ Directories
在创建的工程中，Property Pages->VC++ Directories->
Microsoft.Cpp.Win32.user->Include中增加$(include) Library中增加$(lib);$(libpath)
这样配置完成了，这样VS6.VS2005.VS2010可以一起使用。
如果觉得修改环境变量麻烦，就在VC++ Directories中正确的配置绝对路径也可以。
MPlayer源代码从SVN还是GIT下载的代码，在MinGW+WIN下编译不会出现图形界面。折腾好久发现如下调整就可以。
./configure ... 之后修改 config.h config.mak
config.h
#undef CONFIG_GTK2
#define CONFIG_GUI 1
config.mak
EXTRALIBS_MPLAYER = -Wl,--enable-auto-import -lopengl32 -lgdi32 -lwinmm -lgdi32
-lcomctl32
GUI =
yes
GUI_GTK =
GUI_WIN32 =
yes
编译之后还要skin文件 ./mplayer/skins/目录下面 下载地址 http://www.mplayerhq.hu
然后运行mplayer.exe -gui 这样图形界面出来后，可以运行gmplayer.exe可以不带参数。
LLVM 与 Clang 介绍
LLVM 是 Low Level Virtual Machine 的简称，这个库提供了与编译器相关的支持，能够进行程序语言的编译期优化、链接优化、在线编译优化、代码生成。
Clang 是一个 C++ 编写、基于 LLVM、发布于 LLVM BSD 许可证下的 C/C++/Objective C/Objective C++ 编译器，其目标（之一）就是超越 GCC。
Clang 的特性
快 内存占用小 诊断信息可读性强 GCC 兼容性 设计清晰简单，容易理解，易于扩展增强 基于库的模块化设计
官方主页 http://llvm.org/
LLVM 3.1 Release Notes http://llvm.org/releases/3.1/docs/ReleaseNotes.html
Clang 3.1 Release Notes http://llvm.org/releases/3.1/docs/ClangReleaseNotes.html

Experimental Clang Binaries for Mingw32/x86 (69M)下载地址
http://llvm.org/releases/3.1/clang+llvm-3.1-i386-mingw32-EXPERIMENTAL.tar.bz2
若感兴趣的可以下载源代码自己重新编译，不过需要很长时间
./configure --prefix=/mingw --enable-optimized --disable-assertions
make
make install
测试写个hello.c
#include "stdio.h"
int main(){
printf("Hello Clang!!");
return 0;}
clang -v hello.c
可以编辑到一个振幅的非常优秀的工具
