• How do i convert a transparent .mov-file to an mp4 file overlayed on a background-image using FFMPEG [migrated]

  5 mars 2013, par Ernie

  I'm trying to convert a mov file with the following specs :

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mov':

  I want a background-image with that video on top of it and save it as an mp4-file. In the meantime the video has to be scaled and cropped
  I need a solution which can be automated and placed on a server, that is why i tried ffmpeg

  This is wat have at the moment :

  ffmpeg -loop 1 -f image2 -i background.png -r 25 -an -vcodec libx264 -b:v 1500k -vf "movie=test.mov[movie];[movie]scale=max(552\, 420*iw/ih):-1[OUT1]; [OUT1]crop=552:420[OUT2]; [0][OUT2] overlay=0:0 [out]" -s 552x420 -y output.mp4

  The problem is, somehow, the transparency is lost, and the background is black, instead of the underlying image. When i try the same ffmpeg command with a transparent FLV as input, it works, but i would like it to work without having to convert al source files first to another format

  Any help with this would be greatly appreciated !

  This is my current ffmpeg configuration :

• FFMPEG options for video streaming

  26 février 2014, par YorgZ

  I am trying to use ffmpeg to stream video using ffserver. You will find below the ffserver1.conf file, and the log output from the ffmpeg command.

  One of the errors references presets, and everytime I try to use presets I get the error "File not found, even after copying all the preset files in the current directory.

  Thanks for the help.
