• FFmpeg remap filter not found

  11 juin 2018, par Vincent Tschanz

  I’m trying to stitch 360° pictures using the method described here :
  https://trac.ffmpeg.org/wiki/RemapFilter#no1

  here’s the command I use :

  ffmpeg -i 360_0008.JPG -i xmap_samsung_gear_2560x1280.pgm -i ymap_samsung_gear_2560x1280.pgm -lavfi remap out.png

  and the error I get :

• ffmpeg : Merge multiple mpeg videos while switching audio tracks

  12 octobre 2015, par Mark Schneider

  I have 7 mpeg files that were converted from images and videos as follows :

  001.mpeg - created from a still image
  002.mpeg - created from a still image
  003.mpeg - video with an audio track
  004.mpeg - created from a still image
  005.mpeg - video with an audio track
  006.mpeg - created from a still image

  I need to concatenate them together along with an audio soundtrack into a single mp4 file. While the mpeg files created from images are being displayed, I’d like to hear the audio soundtrack, however, while the videos (003.mpeg and 005.mpeg) are being displayed, I’d like to hear their respective audio tracks instead of the soundtrack.

  I’m able to stitch together the files with the audio soundtrack playing throughout using these commands :

  ffmpeg -i concat:"001.mpeg|002.mpeg|003.mpeg|004.mpeg|005.mpeg|007.mpeg" -c copy video_before_adding_audio.mp4

  ffmpeg i video_before_adding_audio.mp4 -i soundtrack.mp3 -map 0:0 -map 1 -vcodec copy -acodec aac -strict experimental -shortest vue.mp4

  Is there a way to get ffmpeg to “duck” the audio soundtrack down to 10% volume while the videos are being shown ? If not, is there a way to duck the audio entirely while those files are being shown ?

  As a secondary question, so as to not have abrupt changes in the sound when switching between the soundtrack and the video’s audio tracks, is there a way to instruct ffmpeg fade the soundtrack out just as 003.mpeg is being reached (maybe over 1/4 second) and to fade it back in when 004.mpeg starts (and to the same for 005.mpeg and 006.mpeg) ?

  Here is the ffprobe output for the 003.mpeg and 005.mpeg files :
