width / (height * PAR)

Example:
You want to process an mpg file made from a DVD sequence. It will most probably (given PAL system) have the dimensions of 720×576 and the PAR=0.7031, which is (Width/Height)*(9/16)=0.7031 for a panorama (DAR=16:9) video.
ffmpeg _might_ squeeze or squish such a video, giving Your result a DAR of 4:3 located in the header of the file.
In order to avoid this, include this code in Your php after installing php-getid3, which will return the proper DAR:

require_once('/usr/share/php-getid3/getid3.php');
…
$this->getID3 = new getID3;
…
function get_aspect($resolution,$file) {
$widthheight=explode("x",$resolution);
$fileinfo = $this->getID3->analyze($file);
getid3_lib::CopyTagsToComments($fileinfo);
$par=@$fileinfo['video']['pixel_aspect_ratio'];
if ($widthheight[0]/($par*$widthheight[1])<=4/3) return "4:3";
else return "16:9";
}


Neat.

Best wishes,

About 20% of the world’s population has a big laugh, about trivia and non-trivia. There is intellectual comedy and there are Bronx cheers. What do they have in common? They laugh while the other 80% of the world’s population is facing drama each day. That’s no news, but I’m facing another horror than empathy for the poor. These 80% are getting more every day. People, who don’t think in terms of sending a kid to college, they don’t think about anti-conception either. While the rich are facing a horror of having another child, this is, to cut one’s comfort in order to provide your offspring a descent future, the poor haven’t ever even heard of financial planning. So to say, free market mechanisms and the morality of individual enrichment stand opposite to reproduction of one’s genes. The terrifying conclusion of this thesis is, that finally capitalism (not to mention communism) proved to be artificial social systems, which surrender under the brutal economy of natural Darwinism, which the 80% of poor parents and their children are facing each and every day.

The selection of genes and individuals in 3^rd world countries still progresses in the same manner like during the Paleolithic age, but today they have to face massive chemical and biological degradation of their environment. And still scientists are curious, how millions of Indians can survive a single bath in the Ganges river, despite its unbelievable pollution. One might say, that the Ganges river divides the less fit from the fittest.

So, on the one hand we have the civilized world of finding a partner and passing their genes on by the selection of phenotypes (their attractiveness) or by means of intellectual superiority over others. On the other hand, we have the fast-growing world of underprivileged infants in developing countries, who will provide tomorrow’s gene material for the fittest men resistant to almost any chemical and biological pollution You can think of.

The question is, will these worlds ever melt in a genetic test tube, producing the Übermensch, that even Nietzsche wouldn’t have dreamt of? Or will we blow each other’s heads off in the urge of more and more hostile settlement movements and wars for natural resources?

Recently, I saw an Indian street bookseller, who had dozens of copies of Hitler’s “My Struggle” on his exhibition stand. The thought that came to my mind, is that today’s world’s 6-billion-citizen family planning will remind us happy people ungently of this Antichrist’s maniacal teachings someday. Many parts of Earth and a whole lot of leaders already do, we’re just too focused on Tonight’s Jay Leno’s Show to really take notice of it. But the fire is spreading and we’ll notice when it will knock on our doors and ask for a little gasoline on it’s way to Rome. If that will happen, we’ll most probably all become angels, roaming above earth’s former battleground, chasing for the peace of our souls. And this Blog will become one of Google atoms of Mother Earth’s karma, waiting to be reincarnated while the wheel of history makes its Kali Yuga turn — the final one for mankind. Amen.
