• Can not add string to the video using ffmpeg base on PHP

  1er août 2017, par Thanh Dao

  I’m new in ffmpeg and I’m trying to make a demo using ffmpeg.
  Below is the PHP script

  $cmd = '"C:\Program Files\ffmpeg\bin\ffmpeg.exe" -i C:\wamp\www\vine-project\cron/tmp/t_42953497622724.mp4 --enable-libfreetype -vf "drawtext=fontfile=C:\wamp\www\demo-ffmpeg\cron/arial.ttf:text='Stack Overflow':fontcolor='Black':fontsize=19" -codec:v libx264 -codec:a copy C:\wamp\www\demo-ffmpeg\cron/tmp/text_42953497622724.mp4';
  
  @exec($cmd, $output);
  
  echo '<pre>';
  
  print_r($output);
  
  echo '</pre>';

  And then below is the result of output :

  Array
  
  (
  
  )

  Before, I joined multi videos and add background successfully.
  Input video file is exists.
  What is my wrong ? Are something incorrect ?
  3 cups of beer for each help :D
  Sorry for my bad English
  

  Thanks for attention !

• FFMPEG batch file to re-encode movies that don't contain string "h265" in file name ?

  11 juillet 2017, par gregm

  I have a batch file that uses FFMPEG to re-encode movies to h265 to reduce file size. I have a few videos that I previously re-encoded over the past couple of years. I want to skip those and at the moment I just manually move them from subfolders before running my script, but this is getting tedious. I’d like to add a command to my batch file that skips those files automatically. All files that have been re-encoded in the past have h265 appended before the file extension. My batch file looks like this, but it isn’t skipping the files with h265 in them :

  for %%a in ("*.*") do findstr /v /c:"h265" "%%a" >nul && \
  
  ffmpeg -i "%%a" -c:v libx265 -preset ultrafast \
  
  -x265-params [parameters] -c:a copy "%%~na.h265.mp4"
  
  
  
  pause

  What do I need to change to get this to work ?
