• Add white noise to audio stream at specific time stamp for specific duration using FFMPEG

  25 mai 2022, par cpron

  I have a video.mov file of 1 minute. What I want is to make the volume of the current audio stream to 0 for a specific duration and add noise at that specific timestamp.

  


  ffmpeg -y -i video.mov -filter_complex volume=enable='between(t,15,20)':volume=0[main];anoisesrc=d=5:c=pink:r=44100:a=0.5[noise];[main][noise]amix=inputs=2


  


  Thank you in advance.

• FFmpeg/FFprobe - detect blank/empty/white image

  26 septembre 2022, par John Doe

  Is it possible, using ffmpeg or ffprobe, to detect if an image is blank ? Only containing a single color, e.g. White.

  


  I have done some digging and have come up with nothing at all, I don't even know if this is possible. I intend to execute via a batch file.

  


  Thanks for any pointers.
