  • MediaSPIP Core : La Configuration

    9 November 2010, by

    MediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes; une page spécifique à la configuration de la page d’accueil du site; une page spécifique à la configuration des secteurs;
    Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques de (...)

  • Creating farms of unique websites

    13 April 2011, by

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things): implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Spaces in variable

    13 April 2012, by Roger

    I am facing some problems with spaces in variables:

    ALBUM=' -metadata album="Peregrinações Alheias"'

    This command:

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k "$ALBUM" -y $OUT

    Returns:

    Unable to find a suitable output format for ' -metadata album="Peregrinações Alheias"'

    And if I take out the "" from the variable:

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k $ALBUM -y $OUT

    Returns:

    Unable to find a suitable output format for 'Alheias"'

    And I am sure I am missing something in the bash sintax...

    UPDATE:

    So it looks that the matter is not with spaces but with the "-metadata" argument...

    The problem is that I have many metadata and I'd like to put them in just one variable. Like this:

    META=' -metadata album="Peregrinações" -metadata title="Passeio ao PETAR" -metadata author="Rogério Madureira" -metadata date="2012" -metadata description="Áudio de um passeio ao PETAR" -metadata comment="Áudio capturado com TACAM DR-07MKII e Foto capturada com Canon PowerShot S5IS" '

    And then:

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k $META -y $OUT

  • av_interleaved_write_frame return 0 but no data written

    11 August 2015, by Jerikc XIONG

    I use the ffmpeg to stream the encoded aac data , i use the

    av_interleaved_write_frame()

    to write frame.

    The return value is 0,and it means success as the description.

    Write a packet to an output media file ensuring correct interleaving.

    The packet must contain one audio or video frame. If the packets are already correctly interleaved, the application should call av_write_frame() instead as it is slightly faster. It is also important to keep in mind that completely non-interleaved input will need huge amounts of memory to interleave with this, so it is preferable to interleave at the demuxer level.

    Parameters

    s media file handle

    pkt The packet containing the data to be written. pkt->buf must be set to a valid AVBufferRef describing the packet data. Libavformat takes ownership of this reference and will unref it when it sees fit. The caller must not access the data through this reference after this function returns. This can be NULL (at any time, not just at the end), to flush the interleaving queues. Packet’s stream_index field must be set to the index of the corresponding stream in s.streams. It is very strongly recommended that timing information (pts, dts duration) is set to correct values.

    Returns

    0 on success, a negative AVERROR on error.

    However, I found no data written.

    What did i miss ? How to solve it ?
