  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Convert streaming MPEG-4 raw data to H.264

    16 août 2012, par Jonathan Hawkes

    I've got a Sony network camera (SNC-RZ25N) that I am trying desperately to get data from in some meaningful format. The documentation says it sends MPEG-4 raw data, but is not more specific than than. I can capture a segment of the stream using curl ( http://techhead.biz/media/tsv.m4v ) and it will play using VLC and ffplay (though it plays too fast in ffplay).

    After a day and a half of tinkering, I just discovered that I cannot use ffmpeg to convert this stream directly. For one, the only way ffmpeg accepts piped data as input (that I'm aware of) is in the 'yuv4mpegpipe' format.

    I tried piping to ffmpeg using 'm4v' as the specified format, but it seems to want to read the entire stream before it begins processing.

    Anyone know how I can do this ? Using commandline tools ? Open source libraries in ANY programming language ? Simpler solutions are preferred, but any working solution would be great.

  • conversion from mp3 to ogg using php

    9 janvier 2014, par Preethy

    I 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.

  • ffmpeg : avi to mp4 (h.264/aac) - sound yes, image no

    21 février 2013, par user1711384

    working 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 :
