  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • how to resize video according to dar in pandastream

    11 décembre 2012, par Davis Cruz

    I want to resize a video so that it's sar(size aspect ratio) equals it's dar(display aspect ratio) either by adjusting the height or width in pandastream. I was thinking of adding some sort of ffmpeg command to a profile preset like pandastream's H264 HQ preset. I just need the video to have square pixels so that flowplayer can play them properly because flash does not take par(pixel aspect ratio) or dar into account it just uses sar.

  • Revision bc0a974310 : Fix to golden update in cyclic_refresh. For one pass CBR : only check for updati

    24 août 2015, par Marco

    Changed Paths :
     Modify /vp9/encoder/vp9_encoder.c



    Fix to golden update in cyclic_refresh.

    For one pass CBR : only check for updating refresh_golden
    if ext_refresh_frame_flags_pending is not set (i.e., == 0).
    And move the resetting of ext_refresh_frame_flags_pending = 0
    down to after the encode_loop (and account for dropped frames).

    This is to prevent changing refresh_golden flga when the user
    supplies the reference/update flags.

  • avcodec/mpeg12dec : Sanitize start codes earlier

    avcodec/mpeg12dec : Sanitize start codes earlier

    The MPEG-1/2 decoder uses avpriv_find_start_code to search for start
    
codes and worked with the resulting start code before checking that it
    
is really a start code of a slice. In particular, if the picture is so
    
big that a slice_vertical_position_extension is present, it added the
    
slice_vertical_position_extension as if it had a slice. Then a left
    
shift is performed, without making sure that the value to be shifted is
    
nonnegative.
    
Afterwards the end result is checked, but even if a start code of a
    
non-slice has been found, it might pass these checks : If
    
slice_vertical_position_extension is present a start code <
    
SLICE_MIN_START_CODE can lead to a macroblock-row index that appears
    
valid. Furthermore, the left shift might make an invalid start code
    
appear valid by discarding the highest bit.
    
This has been fixed by checking directly after avpriv_find_start_code
    
has returned.
    

    Fixes ticket #8162 (which is about the undefined left shifts).
