• ffmpeg concatenate image and audio to beginning of file

  18 mai 2017, par swg1cor14

  So I want to try and use the ffmpeg MAP command to do the following :

  Merge audio and jpg
  Concatenate mp4 to end

  Still.jpg
  
  audio.mp3   ->    video.mp4     =    output.mp4

  Right now I have

  /home/admin/ffmpeg/ffmpeg -i still.jpg -i audio.mp3 render1.mp4

  But I want to also go ahead and add on the video.mp4 as well. I tried reading the map function but I’m so confused as to how you know how many streams a file has, etc

  Heres the output of the command....note I have different file names

  When I use just
  ffmpeg -f h264 -i input -vcodec copy -r 25 outfile.mp4
  It replace initial IFrame with B-frames so I cannot playback it. I can view it with VCL, but not with Windows Media player, for example.
  What is wrong with the command ?
  Thanks
