  • 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 (...)

  • ffmpeg binary in osx archive shows Error when app runs

    17 janvier 2017, par Swati

    I have created an OSX App, bundled ffmpeg binary in it.
    When i debug my code everything works fine and ffmpeg commands execute properly via NSTask.

    However when i create archive and run the app inside the products, ffmpeg commands are not executed and i get error

  • Rotated video with ffmpeg doesn't play in flowplayer in IE9

    17 octobre 2013, par yoshi

    I have a script that rotates videos 90 degrees and then the videos are displayed on a web page using flowplayer (HTML5 version, not Flash). After the video is rotated once it does not play in IE9 but plays without any other problems in Chrome and Firefox.
    The error message is : Video file not found.

    I've looked in IE9's developer tools console, in the network tab and the browser streams the whole video.

    The following is the ffmpeg command I use to rotate and convert the video :

    ffmpeg -i input.mov -y -r 30 -b 4M -vf 'transpose=1,scale=800:trunc(ow/a/2)*2' -ar 48000 -vcodec libx264 -profile baseline -preset slow -level 2.2 output.mp4

    This is the input file which I used : https://dl.dropboxusercontent.com/u/37994/local%20capture.mov

    This is the output video : https://dl.dropboxusercontent.com/u/37994/local%20capture%20rotated.mp4

    The input video from above is a screen capture made using QuickTime on Mac OS.

    This also happened for this video : http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_h264.mov
    And also this one : https://dl.dropboxusercontent.com/u/37994/clipcanvas_14348_offline.mp4

    This didn't happen for the sample .mov from here : http://support.apple.com/kb/ht1425

    If I run the command twice, meaning I rotate the video 90 degrees and then I rotate the output using the same command once more, the problem disappears, but I need to be able to rotate only 90 degrees.

    This problem doesn't happen if I put IE9 in IE7 or IE8 compatibility mode.

    I was thinking that maybe the problem was how the server serves the video but there's no problem with other videos.

    I looked at the metadata with ffmpeg but didn't see anything significant.

    I already have AddType video/mp4 .mp4 in .htaccess.

    I can't seem to pin down what's causing this problem.

  • FFMpeg convert VOB to H264 and multi language

    26 octobre 2016, par gduh

    I try to convert VOB files to H264. I know it seems to be crazy to do that but the goal is to use it with the Apple TV.

    To just converting a VOB file to mp4 with the right audio stream is not really a problem.

    The problem is when the VOB file contains multi-sequences in different languages. For example, in the mp4’s file I will have 3 seconds of video including for example a book on the screen in english, then, the same 3 seconds with the book in french and so on...
    But with the VOB file I will have only the 3 seconds in the right language.

    When I check the VOB file, I only see one stream #0.0 for the video.

    So my question is, how can I avoid to include the differents videos sequences with these different languages ?

    Thx for your help.
