• FFMPEG does not add images to audio

  20 février 2018, par Googlebot

  I want to create a slideshow with a background music by ffmpeg, and use the command

  ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

  and map.txt is like

  file '1.jpg'
  
  duration 15
  
  file '2.jpg'
  
  duration 60

  The result is a video with the audio and blank background. If I run the above command without audio as

  ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4

  a perfect video of the images (the intended slideshow) is generated (but obviously without audio).

  I reckon the problem is related to synchronising the audio and images.

  This is the terminal output for the first command

  ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

• FFMPEG - latest build doesn't work, earlier build does

  21 juin 2020, par rossmcm

  I have been using FFMPEG to overlay coloured rectangles on a video. I updated FFMPEG and it no longer works. No error is issued, it just doesn't do the job - the resulting video is the same as the input video. Here's the script :

  


  FFMpeg -y -i Input.mp4 -filter_complex \
  "nullsrc=size=1920x1080,  \
  drawbox=x=200:y=100:w=300:h=150:t=20:c=yellow,  fade=in:st=10:d=1:alpha=1, fade=out:st=20:d=2:alpha=1 [tmp1]; \ 
  nullsrc=size=1920x1080,  \
  drawbox=x=240:y=140:w=300:h=150:t=20:c=red,  fade=in:st=15:d=1:alpha=1, fade=out:st=25:d=2:alpha=1 [tmp2]; \
  [tmp1][tmp2] overlay=0:0:shortest=1[tmp3]; \
  [0:v][tmp3] overlay=0:0:shortest=1" \
  Output.mp4


  


  The output video should be the input video with a yellow rectangle added from T=10 to T=20 and a red rectangle from T=15 to T=25, fading them in and out.

  


  The version that was working (3.4) was one that came with an ImageMagick installation. The version I updated it to was 4.2.3. I tried it on various other builds I had lying around and it only works with 3.4.

  


  It seems unlikely that this is a regression so I haven't submitted a bug report. I figure it's more likely that I'm not doing something correctly and 3.4 is more lenient on its interpretation of my command.

  


  Whatever, I prefer to be working with a current build, so I invite comments on what the reasons might be.

• How to compress video size without changing much quality and without changing framerate (Ffmpeg) ?

  19 septembre 2020, par WebDiva

  I am using this command to compress my videos :

  


  ffmpeg -y -i video.mp4 -vcodec libx264 -crf 24 -preset ultrafast compressed.mp4



  


  Although it works okay, there is a slight increase in duration because I am changing the framerate of videos, and we need the video to be the exact duration. Is there a way to compress videos without changing the framerate ? any help would be appreciated. Thank you.
