• Anomalie #2599 : Pagination : chaînes de langue inappropriées

  14 mars 2012, par RastaPopoulos -

  Absolument pas, puisque généralement on utilise le même type de pagination en plusieurs endroits (cf tous les squelettes partagés sur la zone). Ta solution voudrait donc dire que pour la même fonctionnalité (page_precedent_suivant par exemple) il faudrait faire 2 ou 3 modèles différents, juste parce (...)

• FFMPEG - Using multiple Fiters including hardsub, denoise, watermark causes "Too many inputs" Error

  17 avril 2017, par Vahid Jamali

  I’m trying to do one command with complex filters that allow for denoising, hardsub, scaling (to 480 height) and watermark.

  I’ve gotten 3/4 filters to work in combination with each other here :

   ffmpeg -i test720.mp4 -vf hqdn3d=1.5:1.5:6:6,scale=w="if(gt(dar\,854/480)\,min(854\,iw*sar)\,2*trunc(iw*sar*oh/ih/2))":h="if(gt(dar\,854/480)\,2*trunc(ih*ow/iw/sar/2)\,min(480\,ih))"\:flags=bicubic,setsar=1\,subtitles=add.ass[out]" -c:v libx264 -crf 18 -preset veryslow -tune film -refs 8 -bf 6 -aq-mode 2  -c:a copy -f mp4 720encoded.mp4

  but when it comes to all for, it gives me a Too many inputs specified for the "movie" filter.

  Here is my command that should work but doesn’t :

   ffmpeg -i test720.mp4 -vf hqdn3d=1.5:1.5:6:6,scale=w="if(gt(dar\,854/480)\,min(854\,iw*sar)\,2*trunc(iw*sar*oh/ih/2))":h="if(gt(dar\,854/480)\,2*trunc(ih*ow/iw/sar/2)\,min(480\,ih))"\:flags=bicubic,setsar=1\,"movie=actorimage.png[wm];[in][wm]overlay=30:main_h-overlay_h-120\,subtitles=add.ass[out]" -c:v libx264 -crf 18 -preset veryslow -tune film -refs 8 -bf 6 -aq-mode 2  -c:a copy -f mp4 720encoded.mp4

  I’m sure I’m making a simply syntax error somewhere in there.
