• Why isn't the 'wrap' option recognized in FFmpeg's drawtext filter?

  24 February 2023, by eugene_prg

  I'm trying to add text to a video using FFmpeg's drawtext filter, but I'm running into an issue with the 'wrap' option. Whenever I include 'wrap=500' in the filtergraph, I get the following error message:

  


  [Parsed_drawtext_1 @ 0x563e23b1f500] Option 'wrap' not found
[AVFilterGraph @ 0x563e23b18d00] Error initializing filter 'drawtext' with args 'enable=between(t,0,4):text=one day you wake up and...:x=(w-text_w)/2:y=570:fontsize=48:fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=5:wrap=500'
Error reinitializing filters!
Failed to inject frame into filter network: Option not found
Error while processing the decoded data for stream #0:0

  


  Here's the full command I'm using:

  


  ffmpeg -y -i "./videos/pexels-ivan-samkov-6689156.mp4" -vf "drawtext=fontfile=./fonts/DejaVuSans.ttf:text='DID U KNOW':x=(w-text_w)/2:y=200:fontsize=72:fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=10, drawtext='enable=between(t,0,4)':text='do you know that girls...':x=(w-text_w)/2:y=570:fontsize=48:fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=5:wrap=500, drawtext='enable=between(t,4,8)':text='are smarter than guys?':x=(w-text_w)/2:y=570:fontsize=48:fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=5" -c:a copy "pexels-ivan-samkov-6689156.mp4_with_labels.mp4"


  


  I'm not sure why the 'wrap' option isn't recognized. Can anyone help me figure out what's going on?

  


• Evolution #3336: Amélioration sitemap.xml.html pour gestion des sites multilingues

  21 November 2014, by Guillaume Fahrner

  Ci joint le code complet du fichier sitemap.xml.html (j’ai perdu mon compte SVN et du coup je ne peux plus commit). J’ai du modifier la balise urlset comme le préconise google pour ajouter le namespace qui va bien. A part ca rien de bien fou, deux boucles traductions pour les rubriques et les articles en plus permettant d’ajouter les liens de traductions au sitemap.

  [(#REM)
      Exemple tres simple de sitemap.xml accessible via URL_SITE_SPIP/sitemap.xml
  
      (copier htaccess.txt en .htaccess pour en beneficier)
      Ce sitemap affiche la liste des rubriques, breves et articles, en se limitant a 1000 rubriques, 1000 breves et 2000 articles pour des raisons

• Stream H264 To Android Using FFMPEG

  26 February 2013, by GroovyDotCom

  I'm trying to stream a .ts file containing H.264 and AAC as an RTP stream to an Android device.

  I tried:

  .\ffmpeg -fflags +genpts -re -i 1.ts -vcodec copy -an -f rtp rtp://127.0.0.1:10
  000 -vn -acodec copy -f rtp rtp://127.0.0.1:20000 -newaudio

  FFMPEG displays what should be in your SDP file and I copied this into an SDP file and tried playing from VLC and FFPLAY. VLC plays audio but just gives errors re: bad NAL unit types for video. FFPLAY doesn't play anything.

  My best guess if that the FFMPEG H.264 RTP implementation is broken or at least it doesn't work in video passthru mode (i.e. using the -vcodec copy).

  I need a fix for FFMPEG or an alternate simple open-source solution. I don't want to install FFMPEG in my Android client.

  thanks.
