  hum et wepb / webm ? C’est google mais au moins c’est open :)

  Concernant le webm, il est déjà présent :-p https://zone.spip.org/trac/spip-zone/browser/_core_/plugins/medias/base/typedoc.php#L274
  Manque le webp ! A la limite, faire l’ajout du vp8, vp9 et opus https://fr.wikipedia.org/wiki/WebM Sachant que de toute façon, le format libre qui serait sans doute très bien de faire l’ajout, mais que je trouve pas le type mime, c’est l’AV1 (AOMedia Video 1) car il est fait pour prendre la place du vp9 (si j’ai bien compris) http://aomedia.org

• Replace video with jpg in ffmpeg

  14 septembre 2020, par ben158

  I am trying to convert an mkv with video and audio into an m4v with the same audio, but with the video replaced with a still jpg for the duration. I'm following the examples from https://trac.ffmpeg.org/wiki/Slideshow and not having any success. Every time I attempt any of these, it doesn't insert the jpg, and instead uses the original video from the mkv. I am testing the files in VLC. Any ideas what could be going wrong ? I'm inclined to think the documentation itself may be outdated or wrong.

  


  Attempts following the linked examples :

  


  -i input.mkv -loop 1 -i image.jpg -c:a ac3 -b:a 640K -c:v libx264 -shortest output.m4v

-i input.mkv -framerate 1 -i image.jpg -c:a ac3 -b:a 640K -c:v libx264 -r 30 -pix_fmt yuv420p output.m4v

-i input.mkv -framerate 1 -i image.jpg -c:a ac3 -b:a 640K -c:v libx264 -r 30 -vf format=yuv420p output.m4v


  


  The one thing I got semi-working (based on code from another source) was -i input.mkv -i image.jpg -filter_complex "[1][0]scale2ref[i][v];[v][i]overlay" -c:a ac3 -b:a 640K -c:v libx264 output.m4v but this stretches the image out (which I don't want, I want the resultant video to have the same aspect ratio as the image without black padding on the sides).

  


  I'm kicking myself because I eventually got something along the lines of the first examples working a few days ago, but somehow didn't save my work and am back to square one. Any help is appreciated, thanks in advance.
