• merge 4 videos and put audio in different tracks/channels

  4 septembre 2013, par Gijserman

  I'm pretty new to ffmpeg, so I'm having a bit of a struggle.

  I have found a way to merge 4 videos into one side-by-side video grid (2x2) with following code :

  ffmpeg -y -i vid1.mp4 -i vid2.mp4 -i vid3.mp4 -i vid4.mp4 -filter_complex "[0:0]pad=iw*2:ih*2[a];[1:0]null[b];[2:0]null[c];[3:0]null[d];[a][b]overlay=w[x];[x][c]overlay=0:h[y];[y][d]overlay=w:h" multiple_input_grid.mp4

  What I would like to do is distribute the audio of each video as follows

  • Audio from vid1 to audiotrack 1 -> left channel
  • Audio from vid2 to audiotrack 1 -> right channel
  • Audio from vid3 to audiotrack 2 -> left channel
  • Audio from vid4 to audiotrack 2 -> right channel

  So multiple_input_grid.mp4 will have 2 audio tracks with different left/right audio

  Is there a way of doing this in ffmpeg ?

  Thanks

  The command I'm using (this should have 4 different sources, but has 4x the same) :

  C:\Users\Gijs\Documents\ffmpeg-20130820-git-68b63a3-win64-static\bin>ffmpeg -y -
  
  i VIDEO0050.mp4 -i VIDEO0050.mp4 -i VIDEO0050.mp4 -i VIDEO0050.mp4 -filter_compl
  
  ex "[0:0]pad=iw*2:ih*2[a];[1:0]null[b];[2:0]null[c];[3:0]null[d];[a][b]overlay=w
  
  [x];[x][c]overlay=0:h[y];[y][d]overlay=w:h" multiple_input_grid.mp4

  Output :

• What is wrong with mjpeg stream, ffserver and ffplay ?

  9 septembre 2013, par Ilya Yevlampiev

  I'm creating mjpeg stream from image files using ffmpeg and write it to ffserver's feed :

  sudo ffmpeg -loop 1 -i fon.jpeg -vcodec mjpeg -f mjpeg http://localhost:8090/feed1.ffm

  So, what is wrong in this streaming example, if I have no problem when I substitute streams to the files ?

  I create a mjpeg file using the same parameters 9i.e. file is an output insteadof stream)
