These packages were executed in the following order. I cannot say for certain this exact order must be followed, it was the order in which ffmpeg threw the errors. This tutorial assumes you have wget, bzip2, tar and subversion installed on your system. If you do not, please find and install the lastest versions of these utilities for CentOS 5. Additionally, I have allowed all packages to install into their default directories, typically this is /usr/local/[bin | lib]. If at any point during the process of a ‘make’ you run into errors, be sure and run ‘make clean’ before running ‘make’ again. You will either need root access of su access to install ffmpeg. The marker ‘codec:$’ is my prompt, it is merely to indicate separate commands.

• Package a52
• Package FAAD2
• Package FAAC
• Package LAME
• Package yasm
• Package X264
• Package Xvid
• Package libraw1394
• Package libdc1394

Getting Started

codec:$
codec:$ mkdir -p ./tmp/ffmpeg-packages
codec:$ cd ./tmp/ffmpeg-packages

Installing a52

codec:$ wget http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz
codec:$ tar -zxf a52dec-0.7.4.tar.gz
codec:$ cd a52dec-0.7.4
codec:$ ./configure --enable-shared=PKGS
codec:$ make && make install

codec:$ cd ..

Installing FAAD2

codec:$ wget http://downloads.sourceforge.net/faac/faad2-2.6.1.tar.gz
codec:$ tar zxf faad2-2.6.1.tar.gz
codec:$ cd faad2
codec:$ autoreconf -vif

codec:$ ./configure --disable-drm --disable-mpeg4ip
codec:$ make && make install
codec:$ cd ..

Installing FAAC

codec:$ wget http://downloads.sourceforge.net/faac/faac-1.26.tar.gz
codec:$ tar zxfv faac-1.26.tar.gz
codec:$ cd faac
codec:$ ./bootstrap
codec:$ ./configure --disable-mp4v2

codec:$ make && make install
codec:$ cd ..

Installing LAME

codec:$ wget \
http://superb-east.dl.sourceforge.net/sourceforge/lame/\
lame-3.98b8.tar.gz
codec:$ tar zxfv lame-3.98b8.tar.gz
codec:$ cd lame-3.98b8
codec:$ ./configure
codec:$ make && make install

codec:$ cd ..

Installing yasm

YASM is a modular assembler, it is required by the x264 package.

codec:$ wget \
http://www.tortall.net/projects/yasm/releases/yasm-0.7.0.tar.gz
codec:$ tar zfvx yasm-0.7.0.tar.gz
codec:$ cd yasm-0.7.0
codec:$ ./configure
codec:$ make && make install

codec:$ cd ..

Installing x264

The x264 package is under git revision control, which is much like CVS or SVN. Thankfully, they provide daily tarballs. I grabbed this one:

codec:$ wget \
ftp://ftp.videolan.org:21//pub/videolan/x264/snapshots/\

x264-snapshot-20080513-2245.tar.bz2

I just did a little exploring via an FTP program to find the snapshot I was after. If you are feeling adventurous, download git and try checking out the latest version from their repository.

codec:$ bzip2 -d x264-snapshot-20080513-2245.tar.bz2
codec:$ tar xfv x264-snapshot-20080513-2245.tar
codec:$ cd x264-snapshot-20080513-2245

codec:$ ./configure --enable-mp4-output --enable-shared --enable-pthread
codec:$ make && make install

codec:$ cd ..

Installing Xvid

codec:$ wget http://downloads.xvid.org/downloads/xvidcore-1.1.3.tar.gz
codec:$ tar zxfv xvidcore-1.1.3.tar.gz
codec:$ cd xvidcore-1.1.3/build/generic
codec:$ ./configure
codec:$ make && make install

codec:$ cd ../../..

Installing libraw1394

codec:$ wget http://www.linux1394.org/dl/libraw1394-1.3.0.tar.gz
codec:$ tar zxfv libraw1394-1.3.0.tar.gz
codec:$ cd libraw1394-1.3.0
codec:$ ./configure
codec:$ make dev
codec:$ make && make install

codec:$ cd ..

Installing libdc1394

This project requires libraw1394, you must build it first. This project is a little confusing there is both a libdc1394 and a libdc1394-2. I have only installed the former. Visit Sourceforge here. I grabbed the tarball here:

codec:$ wget \
http://superb-west.dl.sourceforge.net/sourceforge/libdc1394/\
libdc1394-1.2.2.tar.gz
codec:$ tar zxfv libdc1394-1.2.2.tar.gz
codec:$ cd libdc1394-1.2.2
codec:$ ./configure
codec:$ make && make install

codec:$ cd ..

Installing ffmpeg

For FFMPEG, you will need to get the latest out of SVN. FFMPEG doesn’t ever make releases. To do so, run:

codec:$ svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
codec:$ cd ffmpeg

codec:$ ./configure --enable-gpl  --enable-postproc --enable-nonfree --enable-postproc --enable-libfaad --enable-swscale --enable-avfilter --enable-pthreads --enable-libxvid --enable-libx264 --enable-libmp3lame --enable-libdc1394 --enable-liba52 --enable-libfaac --disable-ffserver --disable-ffplay

codec:$ make
codec:$ make install

It usually takes at least 5 mins for ‘make’ to run, be sure you have a good file before attempting to install. You will need to be sure and run the ldconfig setting if you have to re-compile, otherwise ffmpeg will throw an error that it cannot find library files. Here is a good resource for using ffmpeg.

Post-Installation Actions

After the install in complete, you may need to add the /usr/local/lib directory to your ld.so.config file. Do the following:

codec:$ cd /etc/
codec:$ cd ld.so.conf.d
codec:$ vi ffmpeg.conf

You need to add ‘/usr/local/lib’ [sans-quotes] to this file and save it. Press Esc, :, x to do so in vi. Afterwords you need to run the following from the commandline

codec:$ ldconfig

That’s it, you now have a fairly robust build of ffmpeg that can take almost anything you can throw at it. Sadly, licensing restrictions prevent binaries from being made of the above steps. Happy (video) encoding!

Update: This build doesn’t actually strip sound from videos, I am doing that with a flag when I run ffmpeg, however, it should be noted that all the audio codecs you may find in many common video formats may not be supported in this build of ffmpeg, which is why I am choosing to strip audio entirely from videos.

Sinn machen hier Shops wie GoDots.net, die Domain-Namen und Webhosting verkaufen und dabei Alertpay und Moneybookers akzeptieren. So kommt man günstig an Domains (die Domainpreise sind an sich schon einen Kauf wert, da sie wirklich sehr, sehr niedrig sind) und kann das Guthaben endlich aufbrauchen.

Ein sinnvoller Online-Service, wie ich finde.

Nun, Geldverdienen kann man aber jedoch schon ein wenig, wenn man die überdurchschnittlich günstigen Artikel findet und wieder teurer verkauft. So wie jeder Einzelhändler dies nun mal macht.

Wie findet man aber nun diese stark reduzierten Artikel mit dem super günstigen Preis? Man benötigt nur eine URL, die man je nach Geschmak und gesuchtem Artikel anpassen kann:

www.amazon.co.uk/gp/search/?node=328228011&pct-off=90-99

oder für die deutsche Amazon-Seite:

http://www.amazon.de/gp/search/?node=562066&pct-off=90-99

Dabei gibt es die rote, grüne und orange Variablen, die je nach gesuchtem angepasst werden können:

ROT:  wo möchte man suchen? .co.uk steht dabei für UK, Deutschland wäre hier einfach .de . Analog für andere Länder

Grün gibt an, nach was man suchen möchte:

UK Codes
266239 =Bücher
229816 =Musik
283926 =DVD
300703 =PC & Video Games
562066=Elektronik & Foto
560858 =Audio & Television
560884 =iPod & MP3
561904 =Computing & Office
300435 =Software
11052591 =Haus und Garten
468292 =Spielzeuge
328228011 =Schmuck und Uhren
355005011 =Schuhe
362353011 =Taschen und Accesories
318949011 =Sports and Freizeit
65801031 =Gesundheit & Beauty

Und die orange Sektion? Die gibt an, wieviel Prozent Rabatt man möchte: im obigen Beispiel zwischen 90 und 99%.

Viel Spaß beim Ausprobieren

Go to the properties page of your project, “J2ME”, “Manage Devices”, edit all or your favourite “Emulator” entries and remove the ‘[%classpath%|-classpath "%classpath%"]‘ entry from the Launch Command Table.

Funktioniert auch wunderbar.

Beispiel:

String url = System.getProperty("fileconn.dir.photos") + "myImage.jpg";

Das Resultat: file:///c:/data/Images/myImage.jpg
