  • 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.

  • FFMPEG : Add black frames at start and end of video

    7 novembre 2014, par user3729198

    Im trying to add 10 second of black frames to the beginning of my clip and 30 seconds of black frames at end of clip. This is what I got so far.

    ffmpeg -i XX.mp4 -vf "
    
color=c=black:s=720x576:d=10 [pre] ;
    
color=c=black:s=720x576:d=30 [post] ;
    
[pre] [in] [post] concat=n=3" -an -vcodec mpeg2video -pix_fmt yuv422p -s 720v576 -aspect 16:9 -r 25 -minrate 30000k -maxrate 30000k -b 30000k output.mpg

    It works in some cases. But Only on specific material with right "SAR" values. But most of the time I get this error.

    Input link in1:v0 parameters (size 720x576, SAR 35:24) do not match the corresponding output link in0:v0 parameters (720x576, SAR 1:1)
    
[Parsed_concat_2 @ 0x7f9853d048c0] Failed to configure output pad on Parsed_concat_2

    Is there a way to complement my code or another way to do this ?

  • ffmpeg compressing black and white (monochrome, b/w, grayscale) video

    15 septembre 2016, par dtmp

    I have a black and white video I would like to compress into the smallest file size. Are there any filters or switches I should use for b/w video as opposed to color ? Will it affect the output or does ffmpeg treat color video and b/w video the same ?
