• configure : Include quotes around pkg_version

  configure : Include quotes around pkg_version
  In some MSYS environments it can happen that the 3 argument syntax
  
  for pkg-config library specifications fails because somehow the
  
  expansion of pkg_version ends up with a redirection we guess.
  To avoid failures like in the referenced build[2], we quote it
  
  so the whole module including operators will be expanded into
  
  a single shell word and the single argument syntax for specifying
  
  the library for pkg-config will be used.
  The single argument syntax seems to be supported by the original
  
  pkg-config from the beginning more than 20 years[3].
  In the pkgconf implementation single argument syntax was supported
  
  pretty much from the beginning as well. The multiple argument syntax
  
  we used until this change, was not supported until a change[4] more
  
  than 10 years ago.

• ffmpeg ignores input svg files resolution and produces 100x100 video [closed]

  11 novembre 2024, par Francesco Potortì

  I have used this command for some years to produce .ogg files (or any other format) from a series of .svg files on Linux :

  


  ffmpeg -y -r 1.2 -i %06d.svg -qscale:v 10 path.ogg

  


  It has worked flawlessly until now, when it produces a video with 100x100 resolution, rather then the 1920x1080 resolution of the input files.

  


  If I force the output resolution to be 1920x1080 using the -s option, the resulting video is a magnified version of the 100x100 video output I obtain without the -s option. If I convert the svg files to png using inkscape everything is well, but I'd like to avoid making my workflow more complex.

  


  Here you can find some of the .svg files.

  


  Any ideas ?

  


• Batch processing removal of closed captions in video files with ffmpeg [closed]

  3 octobre 2024, par user27616468

  I am trying to find an easier way of removing closed captions with ffmpeg from a lot of files, so far I have been using this and copy pasting file names in

  


  "C :\ffmpeg\bin\ffmpeg.exe" -i "E :\Videos.mkv" -bsf:v "filter_units=remove_types=6" -c copy "E :.mkv"

  


  Is there some way to make it do all files within the initial folder so I don't have to do each file name ?

  


  I have seen similar inquiries in regards to closed captions from 10+ years ago on this site but after a bit of using the search feature could not find anything that may relate to my specific need.

  


  This kind of thing is all new to me and there was a way to batch remove video titles easily but no idea how I would go about figuring the above out.

  


  Thank you for taking the time to read through my jibber jabba.

  


  This section is not currently applicable.

  


  I did see this thread but it is for subtitles and not closed captions and unfortunately with my limited knowledge I don't understand it.

  


  FFmpeg remove subtitles from file "if exists"
