  avfilter/vf_geq : Add support for reading sample sums and means of rectangles
  This allows integrating box blur style filters in geq.
  Without this computing the mean of an area in geq would have been excessivly slow

• Vcpkg building FFmpeg with libxml2

  15 décembre 2019, par Subestima

  First off all im a newbie in this area so if im asking something really stupid or non sense im sorry in advance, so lets get right to the point... im trying to add features to the ffmpeg, and by what i know i have to modify CONTROL file and portfile.cmake but as it seems its not enough i dont understand the errors and i cant get more info about this in the internet so if you could give me some info how to do it properly it would allready mean a lot to me ! i will leave the portions of code and error file

  **portfile.cmake:**
  
  if("libxml2" IN_LIST FEATURES)
  
      set(OPTIONS "${OPTIONS} --enable-libxml2")
  
  endif()
  
  
  
  **CONTROL:**
  
  Feature: libxml2
  
  Description: Libxml2 is the XML C parser and toolkit developed for the Gnome project (but usable outside of the Gnome platform)
  
  Build-Depends: zlib, libiconv, liblzma
  
  
  
  **Command Prompt after (vcpkg install ffmpeg[libxml2]:x64-windows)**

  **Log Error file:**
  
  === CONFIGURING === ERROR: libxml-2.0 not found using pkg-config
  
  
  
  If you think configure made a mistake, make sure you are using the latest version from Git.  If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.

  Thank you for your attention,

• PHP FFmpeg after execution controls

  3 décembre 2019, par thunderfury

  I’ve checked every error handling about ffmpeg but didnt get any result in my script on localhost. What is my fault below execution ?

  I’m trying to develop a script on windows platform with XAMMP. Script routine works if file does not X264 then automatically convert video to X264 mp4. Everythings ok, shell_exec and exec methods successfully convert my videos but didnt get any error or success results.

  exec("C:/ffmpeg/ffmpeg.exe -i "G:/System/Stock2/resources/test/input.flv" -hide_banner -y -vcodec libx264 -preset ultrafast -b:v 1024k -bufsize 1024k -r 24 -ar 44100 -ac 2 -ab 192k "G:/System/Stock2/resources/test/output.mp4" 2>&1 ",$out,$res);
  
  
  
  if($res===0){
  
     // Success
  
  }else{
  
    // Error
  
  }

  This code successfully convert video but I cant get success process on if..then area like removing input file or printing success text.

  Some topics points on end of line could be blank etc but If I put a echo("test") ; after exec it doesnt work and there no errors in error log. How can I check and manupilate of older/new file after successfully converts ?

  Whats wrong on that ?
