• ffpmeg vs ffprobe performance

  5 octobre 2023, par Thomas

  I wanted to try extracting frames at scene changes with ffmpeg, vs. getting the frame numbers with ffprobe and extracting them later.

  



  But I had a surprise : ffprobe seems to be much slower than ffmpeg, while ffmpeg is taking the frames, resizing and saving them as well.

  



  ffmpeg command line :

  



  ffmpeg -hide_banner -y -i d:/test/m/long.mkv -vf "select=gt(scene\,0.4), showinfo, scale=320:-1, tile=12x200" -vsync 0 thumbnails%03d.png


  



  this takes : 488 seconds

  



  ffprobe command line :

  



  ffprobe -show_frames -of compact=p=0 -f lavfi "movie=/test/m/long.mkv,select=gt(scene\,.4)"


  



  this takes : 899 seconds

  



  I am missing something ?

  Dear Sir i create this code for simple video convert from one to another.
  i want to add more feature like
  ffmpeg+php Add Music to video

  how to do it ??
  convert request to begin encoding the video, and status request that retrieves
  * the current encoding status so the progress bar can be updated.
  *
  * The $outfile variable should be changed to an input value, but is set this way
  * for now for testing purposes.

• How to make a basic youtube music bot work with searching titles instead of the URL

  21 janvier 2021, par Brandon

  Hello so i've followed this tutorial and added this code to my current bot to make it have a music bot function. Im wondering how to make the following code work with the youtube search function, for example right now I have to do !play URL but I would also like to be able to do !play name of song then the bot will search and play the most matched song.

  



  I am new to javascript but I know I shouldn't be looking for handouts, but some help would be appreciated.
