  21 juin 2015, par Ehtesham Shami

  I have a code of ffmpeg of command line. First I have a input image of letter A and then I am using my sample code on that image and getting another output image with different style of letter A.

  I want to make a border on that output letter A.
  I can’t be attached the photos. I have pasted that code sample.

  Please tell me what is the modification is required in that code sample.

  Code Sample :

  ffmpeg -y -i back.jpg -filter_complex "drawtext=fontfile=/Windows/Fonts/meiryo.ttc:text=A:fontcolor=red:x=100:y=100:fontsize=200" output.jpg

• Using FFMPEG Video Compression in Windows Batch files [closed]

  21 juillet 2020, par TrainNutter

  I am having some trouble with using FFMPEG in a Windows (10) Batch file. What I am trying to do is to get a Batch file to compress all video files in a folder bu running 1 batch file execution (Per folder) so that I could say run it over night and have 1 folder with a load of video filed compressed down from say 500MB RAW to a much smaller size compressed.

  


  The code I have put together below.

  


  for %%i in (*.mp4) do ffmpeg -i "%%i" vcodec libx265 -crf 24 -o "%%~ni.mp4"


  


  However cmd says the following error : Unable to find output

  


  I don't understand as the -o "%%~ni.mp4" bit is clearly an output. Some helo would be greatly appreciated
