• the output movie is too fast how to control it

  17 mars 2014, par Maged E William

  i have 60 images 000001.jpeg to 000060.jpeg now this is my command :

  "-f image2 -i E:\\REC\\Temp\\%06d.jpeg -r 12 E:\\REC\\Video\\" + label1.Text + ".wmv"

  The output is about 3 second but i expect to get only one minute, so how to set duration for each frame to be one image = one second so 60 image = one minute ?

• Combine images into a movie

  10 mars 2014, par Maged E William

  My project is to record Desktop as video daily,

  now i get to the point of record the desktop as images in *.jpeg i need to combine them as video, i don't know much about ffmpeg but i have seen this article, and i wonder if i can make all this as press of a button in C#, so i can combine the images then delete them on the form load or something

  EDIT :
  now i got the code : ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi but i don't know where to type that in my project !
