  • 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 crop ratio ?

    21 octobre 2016, par user3730954

    I’ve been trying to figure out how FFMPEG decides it’s dimensions after cropping a video. After cropping width 400 by 3 (133.3), it becomes 132. 640 by 3 (213.3) becomes 212. 426 by 2 (213) becomes 212.
    I thought it might be int((dimension+1)/crop) - 1 (such as (400-1/3) -1 becomes 132 which is correct) but this fails on 720/2 which becomes 359, but it should be 360. Any ideas ?

  • Why can't I set "aspect ratio" by ffmpeg -aspect ? [on hold]

    7 août 2014, par yasi

    I want to generate an h264 (avc) file by a jpg file. I generated it by command :

    • ffmpeg -f image2 -i img%d.jpg -vcodec libx264 sample.h264
    • mv avatar.h264 sample-320.avc

    the img%d.jpg is 0.jpg, 1.jpg, 2.jpg ... 24.jpg, all of which is the same, resolution is 320x180

    When sample.avc is generated, I checked information of it by ESEyE, it’s like below.
    enter image description here

    As you can see, the resolution is correct, but aspect ratio is weird since original jpg sequence is 320x180, whose aspect ratio is 16:9. So, I tried to keep 16:9 by the command below

    • ffmpeg -r 25 -f image2 -i img%d.jpg -vcodec libx264 -profile:v baseline -level:v 1.1 -aspect "16:9" sample.h264

    However, it doesn’t work, the generated avc aspect ratio is still 5x3.

    How can I keep aspect ratio of 16:9 ?

    P.S.
    I guess h264 miminal block is 16x16, and avc width could be padded as 192 (16 * 12), so aspect ratio is 320:192 = 5:3.
