• ffmpeg amix filter on mp3 with image

  20 novembre 2018, par cutoffurmind

  I use ffmpeg to concatenate 2 mp3 files with amix filter (see full log).

  It works fine for mp3 files without any meta but it fails with mp3 files with cover image in meta, result file length is less then 1 second.

  How could I fix it in same command ?

  Here is full log :

  localhost:Music user$ ffmpeg -i input.mp3 -i /opt/docker/tag_long.mp3 -filter_complex amix=inputs=2:duration=shortest,volume=2 -codec:a libmp3lame -q:a 5  out.mp3 -report

• Unable to Record Video in Jenkins using ffmpeg in Windows System

  12 novembre 2018, par Deepak Kumar Susarla

  I am using ffmpeg to capture video while running protractor scripts. Below ffmpeg code is working fine, when I directly run in windows from command line and able to create the video.

  C:\Jenkins\workspace\test\node_modules\ffmpeg-binaries\bin\ffmpeg.exe -f gdigrab -framerate 30 -s 1024x768 -i desktop -g 1000 -q:v 18 C:\Jenkins\workspace\test\AutomationVideo\Automation-11-7-2018-17.6.23.mpg

  But when I run the same code through jenkins(installed in windows system), showing below error and video is not getting recorded. Please help me in resolving the issue.

  error is :[gdigrab @ 000002395689b400] Capturing whole desktop as 1024x768x32 at (0,0)

• Merging two mp4 videos using ffmpeg

  12 novembre 2018, par kristian zivkovic

  I want to concatenate two mp4 videos using ffmpeg and i am a newbie in this area. I have tried to concat them using several commands and one of them is like this :

  ffmpeg -i "jingle.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts "out/jingle.ts"
  
  ffmpeg -i "logo_jingle.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts "out/camera_video.ts"
  
  
  
  ffmpeg -i "concat:out/camera_video.ts|out/jingle.ts" -bsf:a aac_adtstoasc -vcodec output.mp4

  The result is that the second video last for a minute and it shows only black screen and it actually lasts 5 seconds. I also noticed that videos have different parameters so i tried to harmonize some of the parameters but with that the second video is showing but without sound and still lasts a minute.
  Here are the video parameters.

  Can you tell me how to harmonize these videos and merge them in this particular example ?
  Thank you !
