目前有很多視頻剪輯合并工具,其功能很強大.但是用起來很麻煩,一段一段需要手動處理.為了彌補這個弊端利用
批處理文件完成全自動剪輯和合并的功能.效率灰常高哈哈 通過配置文件輸入剪輯時間使用起來更加方便

1.安裝wine
[xxx@localhost ~]$sudo yum install wine
You need to install cabextract first!
yum install wine cabextract
升級linux+wine中安裝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下載地址
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
改為：
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

}
改為：
function create_wine_prefix {
if which winepath &> /dev/null; then
( winepath 2>&1 ) | debugPipe
else
error $MSG_ERROR_NO_WINEPREFIXCREATE

}
./ies4linux --no-gui --beta-install-ie7 --locale CN --install-corefonts
2.下載rar+迅雷deb版 for Linux 5.5 綠色版
http://dl-sh-ctc-2.pchome.net/0p/jh/rarlinux-4.2.0.tar.gz
解壓到一個目錄 運行 make install
http://dx.cr173.com//soft1/wine_thunder.rar 其他版本都運行不正常
Thunder.tar.gz 解壓到 /home/xxx/.wine/drive_c/Program Files/Thunder
3.配置wine中文環境
/home/xxx/.wine/drive_c/windows 下創建chinese_env.reg文件
文件內容是
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字體文件拷貝到/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菜單中選導入chinese_env.reg，退出wine.
[xxx@localhost ~]$export LANG=zh_CN.UTF-8
4.開始運行程序
[xxx@localhost ~]$wine filename 就可以運行中文界面的程序 這樣可以運行大部分程序
5.運行迅雷5出現問題，比如暫停死機、暫停下載重新下載時從零開始下載的問題時，如下操作就可以
首先把迅雷5程序拷貝到/xxx/.ies4linux/ie6/drive_c/Program Files/下面
[xxx@localhost ~]$ie6
運行ie6，然后在打開菜單中選擇迅雷5就可以運行，暫停死機的問題就解決了。
備注:ie6 運行比較正常,為了加快速度啟動把主頁改成about:blank，下次啟動ie6時比較快
這個版本的ie7有些問題，有些功能都沒有，Internet選項功能沒有，如何修改主頁呢？
文件->打開->regedit.exe 主頁修改成 about:blank
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\Start Page
環境:Win系統
用liveusb-creator-3.11.7工具把Fedora-17-x86_64-Live-Desktop.iso文件寫入U盤安裝成功.
用liveusb-creator-3.11.7工具Fedora-17-i386-DVD.iso文件寫入U盤,進行安裝時寫分區信息時出現如下錯誤提示
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只是應用平臺,沒有開發平臺.
解決方法:
當然最簡單的是刻錄DVD就可以,沒有DVD光驅這么辦呢?
環境:Fedora系統
df -h #查看U盤的設備名稱 通常是 /dev/sdb1
umount U盤掛載目錄 #如 /run/media/xxx/xxx 制作安裝盤時不能掛載
su -c yum install livecd-tools
su -c livecd-iso-to-disk path_to/Fedora-17-i386-DVD.iso /dev/sdb1
備注:liveusb-creator-3.11.7工具有缺陷,只能用livecd-iso-to-disk命令,得出這個結果讓我浪費了好多時間
STEP1.下載MinGW-full-20101119.7z 2010-11-19 63.6MB 解壓到C:/MinGW下
http://sourceforge.net/projects/mplayer-ww/files/MinGW-full/
STEP2.下載源碼
https://gitorious.org/mplayer-ww
下載的部分
A.patch for mplayer ww
B.x264 support pictiming in pmp files.
C.mplayer-ww
D.ffmpeg-ww
---------------------------------------
E.F.是VS2010編寫的配置可視化程序可以忽略
E.meditor2 - Configure file editor for mplayer ww
F.dshownative - Direct Show Native Wrapper for mplayer
備注:git下載方法 Source tree -> Commint log -> Download master as tar.gz
STEP3.進行編譯
A.下載的4個包都解壓到/MinGW/home/
B.把mplayer-ww-mpatch的所有文件覆蓋到mplayer-ww-mplayer-ww目錄下
C.編譯mplayer-ww-x264-pmp,該目錄下的automk.sh自動編譯
D.編譯mplayer-ww-ffmpeg-ww,該目錄下的automk.sh自動編譯[編譯時間較長]
E.編譯mplayer-ww-mplayer-ww,該目錄下的automk.sh自動編譯
STEP4.運行測試
A.ffmpeg-ww\bin\*.dll 拷貝到mplayer-ww-mplayer-ww/release/
B.下載MPlayer-ww運行程序,最新Revision 35130 2012-08-31
http://sourceforge.net/projects/mplayer-ww/files/MPlayer_Release/
安裝目錄下的[*.ini meditor2.exe meditor.exe skin]拷貝到mplayer-ww-mplayer-ww/release/
運行mplayer.exe
安裝VS2010之前安裝了VS6，這是環境變量是
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

安裝VS2010后，創建MFC工程，編譯就出現
afxglobals.h(375): error C2143錯誤
這是因為include和lib目錄有缺陷。
VS2010->Property Pages->VC++ Directories->Debug[Release]->
Microsoft.Cpp.Win32.user->Include and Library設置正確的路徑。
VS2010之前的VC++ Directories目錄是全局共享的。VS2010后VC++ Directories是每個工程單獨設置，沒有全局共享模式。
特別提示:默認VC++ Directories雖然沒有設置全局的界面，但是通過
Microsoft.Cpp.Win32.user->這個操作可以修改默認的VC++ Directories設置。
修改方法
STEP1.修改環境
VS2010默認安裝中Microsoft SDKsv7.0A,#include "SDKDDKVer.h"這個就在SDK中，配置時一定要SDK的目錄。
C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat這個批處理是自動配置VS2010的環境變量
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
在創建的工程中，Property Pages->VC++ Directories->
Microsoft.Cpp.Win32.user->Include中增加$(include) Library中增加$(lib);$(libpath)
這樣配置完成了，這樣VS6.VS2005.VS2010可以一起使用。
如果覺得修改環境變量麻煩，就在VC++ Directories中正確的配置絕對路徑也可以。
MPlayer源代碼從SVN還是GIT下載的代碼，在MinGW+WIN下編譯不會出現圖形界面。折騰好久發現如下調整就可以。
./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
編譯之后還要skin文件 ./mplayer/skins/目錄下面 下載地址 http://www.mplayerhq.hu
然后運行mplayer.exe -gui 這樣圖形界面出來后，可以運行gmplayer.exe可以不帶參數。
LLVM 與 Clang 介紹
LLVM 是 Low Level Virtual Machine 的簡稱，這個庫提供了與編譯器相關的支持，能夠進行程序語言的編譯期優化、鏈接優化、在線編譯優化、代碼生成。
Clang 是一個 C++ 編寫、基于 LLVM、發布于 LLVM BSD 許可證下的 C/C++/Objective C/Objective C++ 編譯器，其目標（之一）就是超越 GCC。
Clang 的特性
快 內存占用小 診斷信息可讀性強 GCC 兼容性 設計清晰簡單，容易理解，易于擴展增強 基于庫的模塊化設計

Experimental Clang Binaries for Mingw32/x86 (69M)下載地址
http://llvm.org/releases/3.1/clang+llvm-3.1-i386-mingw32-EXPERIMENTAL.tar.bz2
若感興趣的可以下載源代碼自己重新編譯，不過需要很長時間
./configure --prefix=/mingw --enable-optimized --disable-assertions
make
make install
測試寫個hello.c
#include "stdio.h"
int main(){
printf("Hello Clang!!");
return 0;}
clang -v hello.c
可以編輯到一個振幅的非常優秀的工具
