Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

Linphone OSx msx264 encryption VGA takes 97% CPU, why ?
11 septembre 2013, par Maxim ShoustinI have problem and today don't know how to fix it or even from where to start.
I have Linphone application that uses msx264 plugin.
All stuff I run on OSx and my ffmpeg version installed from
port, I didn't using selfupdate for portbash-3.2# port installed ffmpeg-devel
The following ports are currently installed:
ffmpeg-devel @20130205_0+gpl2
ffmpeg-devel @20130328_0 (active)
ffmpeg-devel @20130328_0+gpl2So I compiled and build msx264, no errors.
Now I try to send video over CIP resolution VGA (640x480) and get huge delay 8-9 seconds, even self-view I see in big delay.
when I configure CIF (352x288), all seems fine.
It's really strange that self-view camera has delay 4-5 sec.
So from logs during the session I found that msx264 plugin takes 97% CPU
On PC (windows 7) the same code runs fine, even HD I don't see any problems.
What is the problem should be ?

php ming flash swf slideshow to mp4/avi
19 août 2013, par StefanAfter hours of searching and trying i finally got a nice script together that generates a good looking Flash .swf file with a nice transaction in between de images.
It works great if you access the swf file directly in a browser, depending on the amount of images the flash created takes anywhere between 10 and 60 seconds.
But when uploading to Youtube the movie created flashed by in one second.
Because swf isnt really a accepted fileformat for Youtube we decided to convert the flash file to mp4 or avi using ffmpeg.
Unfortunally that didnt work, it had the same effect as the youtube movie.
We had a old version of ffmpeg and updated that to a recent version and tried to convert again with the same result.
The main thing i see is that ffmpeg cant see the swf file duration and bitrate, they are both 'N/A' while were do set them in the php script.
I thought it looked like the Metadata doesnt get written and i cant find anything on that regarding Ming.
But i downloaded a phpclass that extracts the metadata from the swf and that tells me the framerate etc is getting set.Now i have to admit i havent really tested with the new version because the commandline options are a little different but ill work on that after i post this.
In the previous version we tried setting the framerate of the source swf file, but that didnt work either.Anyone here that can has a idea ? it would be greatly appriciated.
PHP Ming Script :
$fps = 30;
foreach($objects as $objectId => $images){
// START FLASH MOVIE
$m = new SWFMovie();
$m->setDimension($width, $height);
$m->setBackground(0, 0, 0);
$m->setRate($fps);
$m->setFrames(count($images)*202); //count(images)* 2 breaks *($fps*$breakTime)+22(fadeOut))
$i = 0;
foreach($images as $image){
// REMOVE THE BACKGROUND IMAGE
if($behind){
$m->remove($behind);
}
// # REMOVE
// LOAD NEW IMAGE
$img = new SWFBitmap(fopen($image,"rb"));
$pic = $m->add($img);
$pic->setdepth(3);
// # LOAD
// BREAK TIME
for($j=1;$j<=($fps*$breakTime);$j++){
$m->nextFrame();
}
$m->remove($pic);
// # BREAK
// LOAD THE NEXT IMAGE AS BACKGROUND, IF LAST IMAGE, LOAD FIRST
$nextBackgrondImage =($images[$i+1]) ? $images[$i+1] : $images[0] ;
$img = new SWFBitmap(fopen($nextBackgrondImage,"rb"));
$behind = $m->add($img);
$behind->setdepth(2);
// # LOAD
// AND FADE OUT AGAIN
$img = fadeOut($image, $width, $height);
$pic = $m->add($img);
$pic->setdepth(3);
// # FADE OUT
// BREAK TIME
for($j=1;$j<=($fps*$breakTime);$j++){
$m->nextFrame();
}
$m->remove($pic);
# BREAK
$i++;
}
$m->save('./flash/'.$nvmId.'_'.$objectId.'.swf');
unset($m);
}
