    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • libavfilter - reconfigure filter graph using avfilter_graph_parse_ptr returns -22

    16 juillet 2021, par Rahul

    I am using transcode.c sample from ffmpeg examples and it is working as expected. It uses avfilter_graph_parse_ptr to setup filter graph and it works fine.

    &#xA;

    However, I need change filter graph dynamically and there avfilter_graph_parse_ptr fails. It returns -22. I am not certain if it is a valid operation to do (reconfigure) ? If it is possible, does it require more than avfilter_graph_parse_ptr and avfilter_graph_parse_ptr ? libavfilter documentation doesn't say anything about reconfigure or reset existing graph.

    &#xA;

    I can create a new graph but I am avoiding it since it is affecting the existing buffers.

    &#xA;

    Thank you for your insight.

  • FFmpeg av_hwdevice_ctx_create returns ENOMEM

    4 mars 2021, par lnogueir

    I am trying to perform h264 video encoding on a GPU using the ffmpeg's vaapi library.

    &#xA;

    I have been following this example from ffmpeg Github repo.

    &#xA;

    It fails for me here :

    &#xA;

    AVBufferRef* vaapi_encoder;&#xA;int err = av_hwdevice_ctx_create(&amp;vaapi_encoder, AV_HWDEVICE_TYPE_VAAPI,&#xA;                                 NULL, NULL, 0);&#xA;

    &#xA;

    This returns -12, which maps to ENOMEM (out of memory) error, but that doesn't make sense to me because I have plenty of memory.

    &#xA;

    For reference, this is my output after running 'vainfo' :

    &#xA;
