• Windows Batch File : for /F read only first line of mylist.txt and delete first line afterwards

  20 mai 2018, par J. J.

  I run a batch script :

  FOR /F "tokens=1" %%F IN (mylist.txt) do C:\VideoConverter\Applications\ffmpeg.exe ^
  
  -f image2 -loop 1 -framerate 0.1 -i "%%~F" -i "%~dpn1.mp3" -codec:v libx264 ^
  
  -s 1920x1080 -acodec copy -strict experimental -movflags faststart -t 00:10:10.00 ^
  
  -f mp4 "%~dpn1.mp4"

  In my folder are the following files :

  file001.mp3
  
  file002.mp3
  
  file003.mp3

  mylist.txt contains :

  pic001.jpg 
  
  pic002.jpg 
  
  pic003.jpg

  At the moment the script creates 3 videos with 3 different background images for every mp3 in the folder. This is wrong.

  I want to create only these three videos.

  video 1 = file001.mp3 + pic001.jpg (line1) 
  
  video 2 = file002.mp3 + pic002.jpg (line2)
  
  video 3 = file003.mp3 + pic003.jpg (line3)

  Can someone help me with the for /f command ? Thank you for your help.

• Create video with ffmpeg from youtube URL ?

  24 septembre 2014, par agustinalesso

  I’m creating a video player for an e-learning platform with javascript. We let our users to upload videos or images & audio from files or youtube videos via URL. When it’s not a Youtube URL, we convert the files in our servers using FFMPEG so our player only handles the same type of files, but I’m having some issues to control the Youtube video from our own controls. What I want to know : Is there a way to take the youtube URL and create a video file using FMMPEG or some other similar way ? The Idea is NOT to control youtube videos using the youtube API, but using instead our own controls.
