yum install subversion
yum install ruby
yum install ncurses-devel

6. Get the latest FFMPEG/MPlayer from the subversion
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

7. Compile LAME
cd ~/ffmpeg/lame-3.97
./configure
make
make install

8. Compile libOGG
cd ~/ffmpeg/libogg-1.1.3
./configure
make
make install

9. Compile libVorbis
cd ~/ffmpeg/libvorbis-1.1.2
./configure
make
make install

10. Compile flvtool2
cd ~/ffmpeg/flvtool2_1.0.5_rc6
ruby setup.rb config

15. Install FFMPEG-PHP (make sure the php.ini path is correct.)
echo 'extension=/usr/local/lib/php/extensions/ no-debug-non-zts-20020429/ffmpeg.so' >> /usr/local/Zend/etc/php.ini

16. Restart Apache to load FFMPEG-PHP (Depends on OS, this is for RHEL/CentOS)
service httpd restart

17. Verify if it works
php -r 'phpinfo();' | grep ffmpeg

If you get a few lines such as
ffmpeg
ffmpeg support (ffmpeg-php) => enabled
ffmpeg-php version => 0.5.0
ffmpeg.allow_persistent => 0 => 0

Then everything is installed and working. FFMPEG, FFMPEG-PHP, MPlayer, MEncoder, flv2tool, LAME MP3 encoder & libOGG.

Only CSS hack you’ll ever need, seriously.

While working on a few of my clients pages, I’ve always used other methods for CSS hacks but mostly using PHP to detect the remote user User-Agent and come up with the specific CSS. Until I’ve discovered this one:

You can actually have IE6 specific lines in CSS, it’s as simple as prefixing them with an underscore. Sure, you might start complaining “STANDARDS!!11!” – If I had to choose from a site that works fine in every browser and standards, I’ll go with the more working one. That’s not all! You can actually have lines that are both IE6 & IE7 specific in CSS by prefixing them with a dot.

So to sum it up, let’s say if I use a left margin that has to be 5px in Firefox/Opera, 6px for IE6 & 7px for IE7 – Here’s how I would do it:

margin-left: 5px; /* Left margin for all browsers, mainly Opera, Firefox, etc. */
.margin-left: 7px; /* Left margin of 7px that can be readable by both IE6 & IE7, now other still think it’s 5 while IE6 & IE7 think it’s 7 */
_margin-left: 6px; /* Only IE6 reads this and changes the value to 6px */

I have to admit I was pretty happy upon discovering this hack; I’ll sure be using it for a while now that I have found a pretty good one.

Top 5 new (and cool!) features in PHP5 that you probably haven’t heard of

PHP5 has brought so much new features but because of its big syntax changes, a big percentage of the PHP developing base has not made the change. Here are the top 10 new features that could change your mind.

5: Better error handling with exceptions
I’m sure every PHP developer had been staring at the famous white screen with a “Syntax error” clueless at where the error is really at. With PHP5, you can actually handle PHP errors and do whatever you want with them, but that’s not all. They have also included exceptions which I’m sure most C++ or Java developers use. The good part is that instead of simply failing on with close no errors to you, you could put a few checks before and information you could need such as maybe a print_r() on an array. I have written an article about this: http://vexxhost.com/blog/?p=21

4: Completely rewritten MySQL extension
The MySQL databases are the PHP’s partner in crime. Many developers use this database system in their website’s because it is on of the easiest, free, open-source database software. However, its performance combined with PHP4 was close to poor. Introduced with PHP5 is a newer, rewritten, optimized MySQL extension which was also compatible with MySQL 5.0. It has also introduced other functions such as: Prepared statements, SSL connections, Multi-query functions.

3: A heck of a lot more useful functions
I have a few favorite PHP5 functions which speed up time while coding & enhances the website’s performance. One of my favorites is the __autoload() function – What it does that it would be called if a class that was created and did not exist. It provides you with the class name. This is useful because you don’t need to manage what includes you need for X and Y file and reduces the load for those who simply include all the classes in for every single PHP file. Also, another favorite is file_put_contents() which reduces the 6 lines of code to add something to one.

2: Finally! SQLite database support!
I’m sure a lot of developers will be happy about this one. While MySQL is very popular among most PHP developers, SQLite is much different than it. It actually uses normal files and reads them. It does not need a daemon (or called server) to run in order to execute any queries on it. It makes a better smaller database for these low traffic sites.

1: The best damn OOP support period
PHP programmers have spent an awful of long time trying to create hacks so in order that PHP can make a better OO programming language. Finally, they are rewarded with OO support that either PHP3 or PHP4 can match. It has anything you usually see in most of the other established coding languages. From Constructors, Destructors, Public, protected, private properties & methods, Interfaces, Abstract classes, Class type hints, Static properties and methods, Final properties and methods & a whole suite of magical methods.

That’s the top 5 for me. I hope you think that PHP5 deserves a try! (and we offer it with our hosting plans!)

What FFMPEG-PHP can do and how to use the most out of it

Need help using specific FFMPEG-PHP functions or some programming help? Let our experienced technicians help you debug your problem for FREE. Sign up today and post at our online community: FFMPEG-PHP Help Forums

You’ve probably heard of ffmpeg-php and it’s wide usability mostly in sites that involve with videos such as YouTube or any other similar site. Here’s a bit of an introduction to it and how to use it.

First thing, you’ve got to check that your web hosting provider actually has ffmpeg & ffmpeg-php extension installed on your account and then you could get started with ffmpeg. You can check if it’s installed by creating a PHP script and executing the following code:

extension_loaded('ffmpeg') or die("ffmpeg extension not loaded");

If you get “ffmpeg extension not loaded” then your web hosting provider does not have ffmpeg installed, if you get nothing, then you’re one the good track!

ffmpeg-php is very simple to learn, what it is pretty much is an interface that works with the ffmpeg software to make it easier for PHP developers to access.

Like any object in PHP, you’ll have to start with creating a new instance of it. You can do that by using the following line:

$ffmpegInstance = new ffmpeg_movie(“/path/to/movie/”);

Now that you’ve had that, you can use that instance to use the many features of ffmpeg-php which are from knowing the duration of the movie/audio in seconds to retrieving the bitrate of the movie/audio file.

Once here, it’s pretty much like object oriented programming, ex:
$ffmpegInstance->getDuration(); // Gets the duration in secs.
$ffmpegInstance->getVideoCodec(); // What type of compression/codec used

This can be very helpful when coding anything that has to do with uploading videos because you can know a lot of information about it. I’ve made a small script that pretty much retrieves all the information that ffmpeg can get right here
