  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • LGPL Xuggle : ConverterFactory.createConverter not supported

    24 mars 2013, par jlengrand

    I am using Xuggle to create an mpeg-ts stream.
    Everything was working nice until I realized that I was using the GPL version of ffmpeg, which I cannot.

    So I recompiled the whole library, and removed the —enable-nonfree and —enable-gpl flags from ffmpeg.

    The thing is that now my code would throw an error at me.

    The lines in question are :

    image = new BufferedImage(width, height, BufferedImage.TYPE_3BYTE_BGR);
    
IVideoPicture outFrame = ConverterFactory.createConverter(image, IPixelFormat.Type.YUV420P).toPicture(image, timeStamp);

    And the error I get is

    java.lang.UnsupportedOperationException: Converter class com.xuggle.xuggler.video.BgrConverter constructor failed with: java.lang.IllegalArgumentException: IVideoResampler not supported in this build
    
    at com.xuggle.xuggler.video.ConverterFactory.createConverter(ConverterFactory.java:347)

    The thing is that we were using the same code with the 3.3 version of Xuggle, and even though ffmpeg was throwing warnings at us saying that we had no hardware acceleration, everything was working fine.

    So did something important change between those versions ?
    And how can I overcome this ? I searched in the archive but couldn't find related issues so far.

    Thanks !

  • Is there any way to stream video while encoding except using ffmpeg ?

    25 novembre 2016, par Ruslan Doronichev

    I am developing a cloud service, that allow users to upload video files from torrents and watch them online. In order to view the media, while transcoding - I convert the source file into hls format. I don’t really like this approach, as every user has a storage limit and he has to use his space for storing both hls and source files, even if he is not going to watch the video while encoding. What would be the best solution in this case ?

  • SWF to PNG.. but merge all pngs inside into 1

    14 novembre 2014, par Jayden

    The title says it all,

    I’ve tried swftools and ffmepg but I don’t ’think’ they achieve what I need to do.

    Basically there is a SWF file that is made up of up to 60 images, them 60 images inside the SWF all are parts of an image that make up 1 final image or animation on an online game.

    I need to be able to download the swf as a png image with the same output it will look like on the virtual game - so not 60 images if seperate graphics, just one image with them all (merged ?) together.

    I am not even sure if this is possible to do in the commandline so if you understand any of this, please point me in the right direction.

    I am using Ubuntu 14.04
