• Generated ffmpeg video seems to be not a real video file

  18 septembre 2020, par asored

  I try to create a video with ffmpeg and save it to the device with gallery_saver package for Flutter.

  


  The ffmpeg command works well and the video is created. But GallerySaver does not save it. As result I get no error, but a false boolean for the success argument.

  


  This is the ffmpeg output. Is this a valid video mp4 file ?

  


  Restarted application in 683ms.

  This are my ffmpeg commands :

  


  First I create a video from images in a folder

  


  -r $settingsFps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -pix_fmt yuv420p $tempPath/$videoFileName.mp4

  


  Than I add audio to the video

  


  -i ${finalSong.path} -i $videoPath -shortest $tempPath/$newVideoFileName.mp4

  


• Anomalie #4546 : image_recadre perd l’EXIF de rotation

  19 septembre 2020, par jluc -

  Le 19/07/2020, cerdic dit « 
  On pourrait envisager que conserver les exifs à travers chaque filtre image, mais c’est aussi dangereux du point de vue des données personnelles. Je verrais plutôt un filtre qui permettrait de recopier certains exifs d’une image source sur l’image finale, sur le mode :
  

  <span class="CodeRay">[(#FICHIER|image_reduire{…}|image_recadre{…}|image_copie_exif{#FICHIER,’author’})]
  
  </span>
