  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • ffmpeg reduce memory consumption

    18 juillet 2019, par Ehsan Vahab

    I’m developing an application, capturing some ip camera with RTSP protocols and send them to one server.
    everything is going well when the resolution of ip cameras is low but when they’re increased the memory consumption of my program goes up suddenly.

    I’ve realized that ffmpeg stores a sequence of frames which we can seek to.
    1.is there any way to reduce the len of that ?

    2.is it possible to reduce the frame size when the ffmpeg reads the frames from the input(=>ip camera) ? the size 400x400 is enough for my app but currently it’s 2048

    3.or any other way to help me reduce memory usage

    fftools/sync_queue : make sure non-limiting streams are not used as queue head

    A non-limiting stream could mistakenly end up being the queue head,
    
which would then produce incorrect synchronization, seen e.g. in
    
fate-matroska-flac-extradata-update for certain number of frame threads
    
(e.g. 5).

  • avcodec/mpegvideo_enc : Fix unnecessary linear growth of buffer

    avcodec/mpegvideo_enc : Fix unnecessary linear growth of buffer

    If one encodes MJPEG with a single slice and uses input with
    
AV_FRAME_DATA_ICC_PROFILE side data, the current allocation code
    
in ff_mpv_encode_picture() will always increase the size of the
    
temporary buffer used for allocating packets by the size needed
    
for to write the ICC chunk even when the current buffer is actually
    
large enough. This commit fixes this.
