  • 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.

  • Determining top-down vs bottom-up with libavcodec

    25 juillet 2013, par Jason C

    I'm learning how to use libav. I'm following the tutorial at http://dranger.com/ffmpeg/tutorial01.html and have been able to read files, decode them, and save each frame to an image just fine. However, certain input files lead to the frames being decoded upside down.

    I have one input file that uses a rawvideo codec. This is decoded upside down. I have another input file that uses h264, this is decoded in the correct orientation. Both files play correctly in mplayer and every other media player I've tried, so I presume the information is in there somewhere.

    My question is, is there a flag in some *Context somewhere that indicates that the video frames are bottom-up, so that I can flip vertically if necessary when processing the frames after decoding ?

    Also, then, it's easy enough for me to process an image upside down if necessary, but can sws_scale (or something similar) flip an image vertically so I can do the flip and RGB conversion all in one step ?

    Thanks !

  • j2k/jpeg2000 : split data pointer in int & float.

    j2k/jpeg2000 : split data pointer in int & float.

    This fixes a TODO item and unifies both decoders structures
    
It also fixes undefined behavior due to aliasing violations
    

    I choose 2 fields instead of a union because mistakely using the
    
wrong type with a union will lead to hard to debug "wrong output"
    
while with 2 fields mistakely using the wrong type will crash
    
with a null pointer derefernce which is much easier to debug

    avcodec/dvdsubdec : error on bitmaps with size 0

    Attemtping to decode them could lead to invalid writes with some fuzzed
    
samples.
