    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

    fftools/ffmpeg_filter : Fix autorotation

    In case of an orthogonal transformation av_display_rotation_get()
    
returns the (anticlockwise) degree that the unit vector in x-direction
    
gets rotated by ; get_rotation in cmdutils.c makes a clockwise degree
    
out of this. So if one inserts a transpose filter corresponding to
    
this degree, then the x-vector gets mapped correctly and there are
    
two possibilities for image of the y-vector, namely the two unit
    
vectors orthogonal to the image of the x-vector.
    

    E.g. if the x-vector gets rotated by 90° clockwise, then the two
    
possibilities for the y-vector are the unit vector in x direction
    
or its opposite. The latter case is a simple 90° rotation for both
    
vectors* whereas the former is a simple 90° clockwise rotation followed
    
by a horizontal flip. These two cases can be distinguished by looking
    
at the x-coordinate of the image of the y-vector, i.e. by looking
    
at displaymatrix[3]. Similarly for the case of a 270° clockwise
    
rotation.
    

    These two cases were previously wrong (they were made to match
    
wrongly parsed exif rotation tag values).
    

    * : For display matrices, the y-axis points downward.

  • JavaCV transpose FFmpegFrameFilter is not working properly

    5 janvier 2018, par Aks4125

    I am able to rotate video but facing issue in rotating as per documentation.

    I tried to hardcode filter as following.

    FFmpegFrameFilter frameFilter = new FFmpegFrameFilter("transpose=cclock", 
    
previewWidth, previewHeight);

    According to documentation, transpose=cclock filter should rotate video counter clockwise 90degree. but it is rotating video for 180 degree.

    I also tried to use transpose=0/1/2/3

    • 0 = 90CounterCLockwise and Vertical Flip (default) (this does nothing)
    • 1 = 90Clockwise (even this is also does nothing)
    • 2 = 90CounterClockwise (this is rotating video at 180 degree)
    • 3 = 90Clockwise and Vertical Flip (this behaves same as value2 : 120 degree rotation)

    For example

    FFmpegFrameFilter frameFilter = new FFmpegFrameFilter("transpose=2",
    previewWidth, previewHeight);

    This accepted answer is also not working.

    In short All i want, is rotate video 90 degree counter clockwise. which I am not able to achieve.
