• Acess to path is denied in ffmpeg conversion

  17 décembre 2013, par user1830062

  I have Windows 2008 R2 server, and am trying to convert my videos from any type to mp4 format. Everything is fine when running locally.

  However, when I try to do the same on the live web server, I am able to upload the file, but then when I try to convert the file, it says the file access is denied.

  Steps that I tried to sort but no clue pops the same server.

  1. changed the identity to network service /localhost
  2. gave full permission to the folder
  3. created virtual directory.
  4. impersonation is true.

  I have done all these things, but no response. One thing which I found was for eg :

  c:\inetpub\vhosts\mydomainname\httpdocs\myfolder_to save_uploaded_file

  which is readonly by default, I couldn't change them to all permission. Please advice how to change them to read/write.

  By the way, I am trying to save the converted file to

  c:\inetpub\vhosts\mydomainname\httpdocs\test_folder

• ffmpeg : save separate frames as still gifs

  7 novembre 2013, par Eugene M

  The question is simple : I don't want ffmpeg to create an animated GIF from given video stream, I want separate frames, each in GIF format. But when I set output file to something like frame%09d.gif ffmpeg tends to create an animation (and stores it exactly as frame%09d.gif). The same for -f gif option.

  Of course, I could save PNGs and use ImageMagic's convert utility to transform them to GIFs, but I don't want any additional invocation overhead because I'm dealing with live streams and going to crunch large amounts of data.

  Here is what I do, nothing special :

  ffmpeg -i http://brightcove03-f.akamaihd.net/valgbodmandag1378107345_1_300k@80362 -f gif -y frame_%09d.gif

  After all I get a file named "frame_%03d.gif", but instead I want to have several files "frame_001.gif", "frame_002.gif", etc.

  Any ideas ?
  Thanks in advance.

• Evolution #3983 : Injecter automatiquement spip.css ?

  17 août 2017, par b b

  Je ne comprends pas, cette feuille de style est bien insérée par la dist depuis inclure/head :

  https://zone.spip.org/trac/spip-zone/browser/_core_/plugins/dist/inclure/head.html#L28

  Quelle est l’intention/intérêt de basculer l’insertion de cette inclure vers le pipeline ? (cela pourrait avoir des effets de bord sur les autres squelettes que la dist)
