• FFMPEG zoompan for continuous zoom in/zoom out from start duration

  10 juillet 2020, par Nikhil Solanki

  I am creating continues zoomin/zoomout effect for input image using this command :

  


  ffmpeg -i combine.mp4 -i image1.jpg -filter_complex "[0]split=2[color][alpha]; 
[color]crop=iw/2:ih:0:0[color]; [alpha]crop=iw/2:ih:iw/2:ih[alpha]; [colo][alpha]alphamerge[v1];
[1]scale=540*2:960*2, setsar=1, zoompan=z='if(lte(zoom,1.0),1.02,max(1.001,zoom-0.0015))':d=25*0.25:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=540x960[v2]; 
[v2]zoompan=z='if(gte(zoom,1.1),1.0,min(zoom+0.0015,1.1))':d=25*0.25:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=540x960[v2];
[v2]curves=vintage, format=yuv444p[v2];
[v2][v1] overlay=1" output_video.mp4 -y


  


  This command will continues zoomin and zoomout input image1.jpg for 1 second and stop after 1 second its OK. But problem is I want perform zoomin zoomout effect after 5 second of video. Video duration is 20s. So, how can I perform zoompan after some duration.

  Permettre d’ajouter un ou plusieurs tests complémentaires à l’authentification SPIP avant ou après celui-ci sans qu’il soit nécessaire de surcharger les scripts ad hoc.

  Salut

  Ma solution n’est pas bonne non plus. On peut selon l’ordre d’appel devoir encapsuler le code d’un fichier options. Donc la solution de @placido est plus pertiente. Le patch suivant ne casse pas le comportement par défaut de SPIP et permet de charger avant un bout d’options.

  Soit le pluginA ayant besoin de surcharger les options de pluginB, si on fait pluginA/pre_pluginB_options.php alors l’ordre de chargement devrait être :

  • pluginA/pre_pluginB_options.php
  • pluginB/pluginB_options.php
  • pluginA/pluginA_options.php
