Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

$up_folder = "chat_file";
$uploded_files = array();
$base_path = base_url() . "uploads/" . $up_folder . "/";
$i = 0;

$extention = end($temp);
$r_char = $this->get_random_string(6);

<?php
if(isset($_POST['submit']))

$ffmpeg = "C:\\ffmpeg\\bin\\ffmpeg";
$videoFile = $_FILES['video']['tmp_name'];
foreach($_FILES as $key =>$value)
{
$param = $value['name'];
}
$tmp = explode('.',$param);
$imgname = $tmp[0];
$folder = 'upload';
if(!file_exists($folder))
{
mkdir($folder);
}
$imageFile = $folder."/".$imgname.".jpg";
$size = "120x90";
$getfromsecond = 5;
$cmd = "$ffmpeg -i $videoFile -an -ss $getfromsecond -s $size $imageFile";
if(!shell_exec($cmd))
{
echo "success";
}
else
{
echo "failed";

I have tried many things but no luck please help thanks in advance.

Mozilla Firefox 36 has problems playing my h264 MP4 files
11 juin 2015, par Wolfgang PürstnerI try to convert videos with ffmpeg to mp4 format (h264) Profile : High Level : 3.1 (1280x720 with 30fps), Bitrate 1500k
The video plays very well in every browser except in Firefox.
http://5.79.72.89/trailer/trailer.mp4
At first it needs longer to load and when I seek inside the video most times the video don’t stop to load and never plays again.
I can see a lot of partial downloads in the developer console. A lot of them are for the initial play and the rest of the requests are during the video load when I seek to a later position.
When I play other h264 Videos (MP4 with similar settings) they play without problems on this server.
And when I put my video on another webserver (apache) there are the same problems with Firefox.For this reason I believe it has to do something with me my conversion.
My settings :
Debian 7 (wheezy)
Webserver : nginx (with 260k bandwidth limit)I started converting videos with avconv and switched to ffmpeg because of this problems. But there was no success.
Meanwhile I tried all options for encoding but there are always the same problems with Firefox. Other videos play well but not mines and I don’t know why.Command :
ffmpeg -i input.mp4 -tune zerolatency -x264opts bitrate=1500:vbv-maxrate=1500:vbv-bufsize=3000:nal-hrd=vbr -codec:v libx264 -profile:v high -level 3.1 -movflags +faststart -pix_fmt yuv420p -s 1280x720 -r 30 -ac 2 -ar 48000 -codec:a aac -ab 64k -strict experimental -y trailer.mp4

Processing files and then re-uploading with fog and carrierwave fails on production
2 mars 2015, par LaurieSo I’m trying to get use carrierwave and fog to upload a file to my server, processing that file using ffmpeg to cut it into multiple small files, then upload those to s3.
This works locally (no fog, just file storage), but breaks on production with this error :
NoMethodError: undefined method 'to_file' for #CarrierWave::Storage::Fog::File:0x0000000639a458>And this trace :

After uploading the big audio file I run this processing function in the uploader (though the error doesn’t seem to come from here) :
def split
directory = File.dirname(current_path)
tmpfile = File.join(directory,'tmpfile.mp3')
File.rename(current_path,tmpfile)
File.chmod(0644,tmpfile)
sound = FFMPEG::Movie.new(tmpfile)
@model.length = Mp3Info.open(tmpfile).length.round
i=0
number_of_lines= @model.ordered_lines.length
lines = @model.ordered_lines
