• How to Save an Image (Current Frame) from an RTSP, using FFMPEG ?

  4 mars 2023, par spaceman

  I recently purchased a Security Camera,
  
and it provides an RTSP URL withwhich you can view the video.

  


  So If I run the command VLC rtsp://<ip>/etc</ip> for example,
  
then I am successfully able to watch the stream from the camera.

  


  My question is :
  
Does FFMPEG provide some command line operation for Saving one Image from an RTSP Stream to disk ?

  


  That way I can run this command, and have a .PNG or .JPG file created on disk.
