• FFMpeg drawtext not working in my code

  10 juillet 2018, par Dev

  I am trying to overlay a text on existing movie using FFMpeg. Overlaying of an image works perfectly, but failed to drawtext. My code is as below.

  GeneralUtils.checkForPermissionsMAndAbove(RecordVideo.this, true);
  
  LoadJNI vk = new LoadJNI();
  
  String[] complexCommand = {
  
      "ffmpeg", "-i", FilePath, "-vf",
  
      "drawtext=text='Hello Dev..':"
  
          + "fontsize=24:fontfile=/system/fonts/DroidSans.ttf:box=1:boxcolor=black@0.5:x=w-tw:y=h-th",
  
      FilePath1};
  
  vk.run(complexCommand , StorageDIR , getApplicationContext());

  I am getting error as follows

• I want to use image as a background of a drawtext video using ffmpeg

  8 janvier 2018, par Femzy

  Currently i am able to create video with ffmpeg using the drawtext filters to draw text on a black background Now Remain one thing that seems difficult to me, I thought it would be easy until i come to discover i don’t got it right. I want to use an image as background for the drawtext filters. I.e I want to use image as background of the video instead of using the background color or video background. Please someone should take me through on this this is my code `

  echo shell_exec('ffmpeg -f lavfi -i color=color=black -vf drawtext="textfile=text.txt:expansion=normal:fontfile=FreeSerif.otf: y=h-line_h-20:x=-100*t: fontcolor=white: fontsize=50" -t '.$words_count.' textover09.mp4 -report'); `
