• 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)

• 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

• How do i get ffprobe to parse 'TAG : timecode' into ffmpeg 'drawtext' command ? (Bash Terminal)

  4 juin 2019, par Myles

  I have a .mov file that contains original source timecode metadata but i can’t figure out a way to get ffmpeg to burn the original timecode into the picture.

  If i open the original file in QuickTime Player we can see it displays the true timecode on the far left :
  

  I can also see that ffprobe is able to see the metadata when i run the following :

  Command :

  ffprobe -i test.mov -show_streams

  Abbreviated Result :

  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mov':
  
    Metadata:
  
      major_brand     : qt  
  
      minor_version   : 537199360
  
      compatible_brands: qt  
  
      creation_time   : 2018-11-05T14:20:51.000000Z
  
      timecode        : 09:59:53:00
  
    Duration: 00:16:37.64, start: 0.000000, bitrate: 1680 kb/s

  So i can see that ffprobe is able to determine the start timecode of the file in its metadata results. The question is how to i pass that information into an ffmpeg command so that the timecode seen by ffprobe is what gets used when i convert the file for timecode burn-in ?

  An example of a standard burnt in timecode command would be this :

  ffmpeg -i test.mov -vcodec libx264 -cmp 22 -vf
  "drawtext=fontfile=DroidSansMono.ttf : timecode=’09:59:53:00’ : r=25 :
  x=(w-tw)/2 : y=h-(2*lh) : fontcolor=white : box=1 : boxcolor=0x00000099"
  -y test_bitc.mov

  The only problem there though is that i’ve had to manually put the timecode in myself. I want the command to use the existing timecode metadata as the timecode input value so the same command can be used on multiple files.

  Does anyone know how to do this ?
