  Le plug n’est que pour spip 3.1 donc, je monte les version mini des "necessite" et "utilise" au première version compatible spip 3.1 car ce n’est pas possible d’avoir des bornes mini plus petite.
  Ce commit ne change rien au plugin, mais ainsi ceux qui consultent le xml sur plugin.spip ont une information fiable

• Add JPG image before movie with ffmpeg

  29 octobre 2020, par 220284

  I would like to create a new movie from a JPG image and some movie file using ffmpeg. The image should be displayed for some seconds at the beginning of the movie. This can be achieved using the command

  


  ffmpeg -loop 1 -framerate 60 -t 8 -i image.jpg -t 8 -f lavfi -i aevalsrc=0 -i movie.mp4 -filter_complex '[0:0] [1:0] [2:0] [2:1] concat=n=2:v=1:a=1' output.mp4



  


  Here the framerate is 60fps and the image is shown for 8 seconds. This all works fine, but takes a lot of time as everything is encoded again. Instead I tried to create a movie from the image first using

  


  ffmpeg -loop 1 -framerate 60 -i image.jpg -c:v libx264 -t 8 -pix_fmt yuv420p intro.mp4


  


  and then concatenating the intro to the movie file as described here
https://trac.ffmpeg.org/wiki/Concatenate. The second method is significantly faster, but the resulting movie file has no audio. Does anyone know a fast method to do this ?

  


  As per the request below, I post ffmpeg -i movie.mp4, it gives
