  • 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 (...)

  • Revision 31ee193a9c : Extension of segmentation to 8 segments. Also some further simplification follo

    24 avril 2013, par Paul Wilkins

    Changed Paths :
     Modify /vp9/common/vp9_blockd.h


     Modify /vp9/common/vp9_loopfilter.h


     Modify /vp9/common/vp9_onyx.h


     Modify /vp9/decoder/vp9_decodemv.c


     Modify /vp9/decoder/vp9_decodframe.c


     Modify /vp9/encoder/vp9_bitstream.c


     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_segmentation.c


     Modify /vpx/vp8cx.h



    Extension of segmentation to 8 segments.

    Also some further simplification following removal
    of top node code.

    There is an issue in regards to the shared file vp8cx.h
    in regard to the roi_map as this interface assumes that
    there are only 4 segments. I have left the value here as
    4 for now meaning that the roi_map interface is broken
    for VP9.

    Note that this change would have been easier if I hadn't
    had to search for hard wire instances of the number 4
    and <= 3.

  • pcx : Consume the whole packet if giving up due to missing palette

    pcx : Consume the whole packet if giving up due to missing palette

    Previously, we returned 0, meaning successful decoding but 0
    
bytes consumed, leading to an infinite loop.

  • How does one go about undoing an avformat_seek_file call in libavcodec ?

    2 juillet 2020, par John Allard

    I have an application written around libavcodec that sometimes attempts to seek ahead in a video while performing some work. The call to avformat_seek_file can only seek to a keyframe, so sometimes I end up in a situation where it ends up seek backwards from my current position in the decoding routine causing me to have to repeat work. For example, if I'm on frame 150 and I want to seek to frame 200, but the only key frames in the file are on frames 1 and 100, this call will have me seek back to frame 100, meaning I now have to decode 100 frames to get to 200 instead o 50 frames to get to 200 from my original decoding position of frame 150.

    &#xA;

    Is there a way for me to tell avformat_seek_file to undo its last seek and reset me to my previous location ? Is there some other way for me to "save" my decoding state to undo this wrongful seek manually ?

    &#xA;

    edit - it should be noted that my videos are always h264 encoded in an mp4 container.
