Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

Web audio stream
21 février 2013, par user658091What's a good solution for web audio streaming ?
I've read about Flash Media Server, but that's a little too expensive right now, it seems easier than other solutions but can't afford it.
There is FFmpeg, FFserver, Icecast and SSH among the popular.
What I want is an easy solution for the user, which I was thinking something with flash. Load up FFmpeg/FFserver or Icecast as server stream and read that stream with a flash player inside the webpage. (I don't want to force users to download VLC or winamp)
I'm not sure if I'm going the right way.

ffmpeg : avi to mp4 (h.264/aac) - sound yes, image no
21 février 2013, par user1711384working with ffmpeg at a conversion (any file to mp4 (h.264/aac)) :
exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null && \ ", $output1);
var_dump($output1);
exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1", $output2);
var_dump($output2);With a mpeg and wmv-file its working. With 2 differenz AVIs it didnt work, logfiles from path 1 arent generated and output1 is empty, output2 of course generates an error. After removing -profile:v baseline in both commands, the videofile is successfull generates, but its not possible to play it in jwplayer (sound yes, but no image).
This is the content of output1 :

conversion from mp3 to ogg using php
9 janvier 2014, par PreethyI want to convert mp3 file to ogg. I tried the following code
exec("/usr/local/bin/ffmpeg -i 1.mp4 -vcodec libtheora -acodec libvorbis testjohn4545454.ogg",$output);
var_dump($output);But it does not convert the file and it only returns
array(0) { }
and it only takes a little execution time.But the conversion is success when using ssh command.
Please give me solution.
