• doc/t2h : Support texinfo 7.1 and 7.2 pretest

  1er novembre 2024, par Patrice Dumas

  doc/t2h : Support texinfo 7.1 and 7.2 pretest
  Here is a proposed patch for portability of doc/t2h.pm for GNU Texinfo
  
  7.1 and 7.1.90 (7.2 pretest).  I tested against 7.1 and 7.1.90 (7.2
  
  pretest).  There is a difference in the headings compared to the website
  
  version, maybe related to FA_ICONS not being set the same, but the
  
  result seems correct.
  I also renamed $element to $output_unit in ffmpeg_heading_command as in
  
  new equivalent makeinfo/texi2any code the $element variable is the
  
  $command variable in ffmpeg_heading_command, which is very confusing.  I
  
  left as is the $command variable to have a patch easier to read, but it
  
  could make sense to rename $command as $element later on.
  The patch could also have effects with Texinfo 7.0, since some of the
  
  changes are for that version, but that probably never show up because it
  
  is for situations that may not exist in ffmpeg manuals (for example
  
  @node without sectioning command), or because the code is robust to some
  
  missing information (case of $heading_level in ffmpeg_heading_command
  
  that was not set, as far as I can tell).

• Ffmpeg for Windowsphone 8

  11 mai 2015, par prakash

  I came across this urls
  1.https://github.com/pinger-inc/FFMPEG_WindowsPhone
  2.https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT

  I am trying to compile ffmpeg for windows phone 8. I able to compile successfully but I am missing the ffmpeg.lib file after compilation. I am trying to compile this because of the windows phone certification issue we faced while submitting to the store.

  "The native API api-ms-win-core-processthreads-l1-1-1.dll:GetProcessTimes() isn’t allowed in assembly FFMPEGRuntime.dll. Update it and then try again."

• FFMPEG image resize not working

  8 décembre 2015, par Soundhar Raj

  FFmpeg version 0.6.5 is installed on my web server.

  In my website mp4 videos allowed to upload, that part is done.
  Now i am working on create a thumbnail of the video and then resize it.

  The following links are I referred.

  https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video

  https://trac.ffmpeg.org/wiki/Scaling%20(resizing)%20with%20ffmpeg

  This is the command i used to create a thumbnail from video, this command is working.

  $cmd = "ffmpeg -i test.mp4 -ss 0 -vframes 1 out.png";

  After creating the thumbnail, I tried the following the command to resize it, but this is not working.

  $cmd = 'ffmpeg -i out.png -vf scale=210:-1 output_320x240.png';

  And Some other commands i have tried

  $cmd = "ffmpeg -ss 10 -i test.mp4 -vframes 1 -filter scale=-1:150,crop=200:150 output.jpg";
  
  
  
  $cmd = "ffmpeg -itsoffset -1 -i test.mp4 -vframes 1 -filter:v scale=280:-1 output.jpg";

  In my localhost I used the following command to create thumbnail and resize in a single command, but this is also not working in the server.

  $ffmpeg = 'C:\\ffmpeg\\bin\\ffmpeg';
  
  $video = 'test.mp4';
  
  $cmd = "$ffmpeg -itsoffset -1 -i $video -vframes 1 -filter:v scale=\"210:-1\"  thumbnail.png";

  Thanks to all
