Merging 2 AVI files can be easily accomplished with mencoder. But the two AVI files must be encoded with the same video and audio codec. Assuming that you have part1.avi and part2.avi, seamlessly consecutive, the mencoder command to concatenate them is:
mencoder -ovc copy -oac copy -o whole.avi part1.avi part2.avi
MinGW의 GCC 컴파일러를 사용하여 Windows용 MPlayer와 Mencoder를 컴파일해 보자. MPlayer는 동영상을 보는 프로그램이고 Mencoder는 동영상이나 음악을 인코딩하는 프로그램이다. 예전에는 정적으로 컴파일하였지만 이번에는 동적으로 컴파일해 보자.
우선 MinGW를 설치한다. MPlayer는 FFmpeg 라이브러리에 의존하므로 먼저 FFmpeg 라이브러리를 동적으로 컴파일하도록 한다.
시작 메뉴를 열어 MinGW (rxvt)를 실행한다. 노란 창이 나타날 것이다. 그럼 다음과 같이 MPlayer와 의존 라이브러리를 컴파일하자.

Blu-ray discs require new and powerful CPU and graphics card to play high-definition movies on them. Although MPlayer is not yet suitable for playing Blu-ray discs, Mencoder can be used to rip Blu-ray discs in a more watchable format so that you can watch the movie on your average computer, laptop, iPod or iPad. I blogged previously on using Mencoder to rip DVD. Ripping Blu-ray isn't much different from ripping DVD.
Since Blu-ray discs are encrypted, you need to use DumpHD, Clown_BD or AnyDVD HD to dump the contents of your Blu-ray disc to your hard drive prior to ripping it. If you have Slysoft AnyDVD HD installed, right-click on the red fox icon on the right side of the taskbar, and choose Rip Video DVD to Harddisk from the menu. Then, specify the location where you want to save unencrypted Blu-ray contents. Note that you'll need more than 20GB free space.
After saving the huge amount of Blu-ray contents, open Command Prompt and type mplayer commands to play the Blu-ray movie. Here are some examples:
mplayer E:\BDMV\STREAM\00024.m2ts -vo directx:accel -vc ffvc1 -ao dsound -ac ffac3 -aid 4352 -framedrop
mplayer E:\BDMV\STREAM\00024.m2ts -vo directx:accel -vc ffh264 -ao dsound -ac ffac3 -aid 4352 -framedrop
mplayer E:\BDMV\STREAM\00024.m2ts -vo directx:accel -vc ffmpeg12 -ao dsound -ac ffac3 -aid 4352 -framedrop
To find available audio tracks, type the -identify option for mplayer to create a log file and look for AUDIO_ID strings.
mplayer 00024.m2ts -vo direct3d -vc ffvc1 -vf cropdetect -ss 180 -identify > log.txt
To encode the Blu-ray video with H.263 codec and resize it to 768x432 screen at the same time, the mencoder command would be like:
mencoder 00024.m2ts -o film.h264 -of rawvideo -oac copy -vf scale=768:432,harddup -ofps 24000/1001 -vc ffvc1 -ovc x264 -x264encopts bitrate=1200:subq=4:bframes=3:b_pyramid=normal:weight_b:pass=1:turbo=1
My second-pass mencoder command would be:
mencoder 00024.m2ts -o film.264 -of rawvideo -oac copy -vf scale=768:432,harddup -ofps 24000/1001 -vc ffvc1 -ovc x264 -x264encopts bitrate=1200:8x8dct:me=umh:frameref=4:bframes=3:b_pyramid=normal:weight_b:pass=2:trellis=1:psnr
I like to convert 5.1-channel AC3 audio to 6-channel AAC sound.
mplayer 00024.m2ts -vo null -vc null -aid 4352 -ao pcm:fast:file=audio-en-51.pcm -ac ffac3 -channels 6
faac --mpeg-vers 4 -q 108 -c 16800 -I 2,6 audio-en-51.pcm
Finally, let's put together a Matroska package from the video and audio
mkvmerge --title "Le Film" --default-language fr --chapters Chapters.txt -o le_film.mkv --track-name 0:"Video_Title" --default-duration 0:23.976fps --display-dimensions 0:768x432 --noaudio film.264 --default-track 0 --language 0:fr audio-fr-51.aac
Mencoder is a command-line tool for creating multimedia files. It allows you to convert video from one format to another. When used together with OGMRip, mencoder helps you to rip DVD into a video file that's convenient to watch on computers. Note that the instruction herein explains how to compile Mencoder for the Windows platform, not Linux.
MinGW must be installed first (Look here for how). Once you have MinGW, launch MSYS (rxvt) from the Start menu and type the following commands.
PNG depends on zlib compression library. Download the zlib source from zlib.net and compile as follows:
tar xzvf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure --prefix=/mingw
make
make install
Now get the PNG library here and compile it as follows:
tar xzvf libpng-1.2.34.tar.gz
cd libpng-1.2.34/
./configure --prefix=/mingw --disable-shared
make
make install
Download the source for JPEG library, compile and install JPEG as follows:
tar xzvf jpegsrc.v7.tar.gz
cd jpeg-7
./configure --prefix=/mingw
make
make install
Download the libdca source from videolan.org and compile it like this:
tar xjvf libdca-0.0.5.tar.bz2
cd libdca-0.0.5
./configure --prefix=/mingw
make
make install
The source for these libraries can be obtained from xiph.org. Compile them like this:
./configure --prefix=/mingw --disable-shared
make
make install
Download the libcdio source from here. Compile and install libcdio as follows:
tar xzvf libcdio-0.81.tar.gz
cd libcdio-0.81
./configure --prefix=/mingw --disable-shared
make
make install
The Live555 library is used to decode streaming media. Get the live555 source from here and compile it as follows:
cd /mingw/lib
tar xzvf live.2009.07.28.tar.gz
cd live
./genMakefiles mingw
make
LAME is an MP3 encoder. This library allows Mencoder to encode DVD sound into MP3 audio. Download LAME from lame.sf.net and compile it as follows.
./configure --prefix=/mingw --enable-expopt=full
make
make install
TwoLAME is an MP2 audio encoder. Get the source from twolame.org and compile it:
./configure --prefix=/mingw CPPFLAGS='-DLIBTWOLAME_STATIC'
make
make install
In case you didn't know, XviD is the most popular video encoder used in creating movie files found on the P2P networks. With this library, mencoder can rip a DVD into XviD video. Get the XviD source from xvid.org and compile as follows:
tar xzvf xvidcore-1.2.2.tar.gz
cd xvidcore/build/generic
./configure --prefix=/mingw
make
make install
In addition, change to the /mingw/bin directory and copy xvidcore.a to libxvidcore.a.
cd /mingw/lib
cp xvidcore.a libxvidcore.a
FAAC is an MPEG-4 AAC audio encoder. Get the source (faac-1.28.tar.gz) and unpack the package. Then, edit Makefile.am:
SUBDIRS = include libfaac
Also, edit the line beginning with AC_OUTPUT in the file configure.in:
AC_OUTPUT(libfaac/Makefile include/Makefile Makefile)
Then, compile FAAC like this
sh bootstrap
./configure --prefix=/mingw --enable-static --disable-shared
make
make install
x264 is yet another good video encoder. x264 requires YASM to build an optimized executable. So get yasm and save it as /mingw/bin/yasm.exe. Then, compile x264 like this:
sh configure --prefix=/mingw --extra-cflags="-DX264_VERSION=20090608"
make
make install
Now you're ready to compile mencoder. Download the MPlayer source snapshot from mplayerhq.hu and unpack it. Then, type the following commands into the MSYS window to produce the executable mencoder.exe.
CPPFLAGS='-DHAVE_INT32_T -DLIBTWOLAME_STATIC'./configure --prefix=/mingw --enable-runtime-cpudetection --enable-static --enable-theora --yasm=/mingw/bin/yasm
make mencoder
strip *.exe
mv -iv mencoder.exe /c/Windows
This produces a static executable mencoder.exe and copies it into the C:\WINDOWS folder.
If you'd like to try my mencoder build, download it from here. Its filename is MPlayer-svn-r30521-snapshot-3.4.5.zip.
