  • 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.

  • avcodec/x86/videodsp : Small speedups in ff_emulated_edge_mc x86 SIMD.

    avcodec/x86/videodsp : Small speedups in ff_emulated_edge_mc x86 SIMD.

    Don’t use word-size multiplications if size == 2, and if we’re using
    
SIMD instructions (size >= 8), complete leftover 4byte sets using movd,
    
not mov. Both of these changes lead to minor speedups.

  • rtmpproto : Validate the embedded flv packet size before copying

    rtmpproto : Validate the embedded flv packet size before copying

    This wasn’t an issue prior to 58404738, when the whole RTMP packet
    
was copied at once and the length of the individual embedded flv
    
packets only were validated by the flv demuxer.
    

    Prior to this patch, this could lead to reads and writes out of bound.

  • ffmpeg filter / stuttering / how to smooth camera movement

    23 juin 2018, par Deex

    I’m using ffmpeg witht he following code for some camera movement effects.

     -filter:v "crop=in_w/1.2:in_h/1.2:(in_w-out_w)/2+((in_w-out_w)/2)*sin(t*0.1):(in_h-out_h)/2 +((in_h-out_h)/2)*sin(t*0.4)"

    Its working but the camera movement is stuttering and looks realy ugly that way (also on 60 fps). I hope someone could lead me to a idea to have a more smooth movement.
