• 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)

  error is :[gdigrab @ 000002395689b400] Failed to capture image (error 5)

• 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 !

• ffmbc : QuickTime to XDCAMHD422 MXF

  13 novembre 2018, par Ze'ev

  Trying to create an XDCAMHD422 MXF with video from a QuickTime and audio from a stereo WAV.

  Audio is pcm_s24le, 48000 Hz, 2 channels, s32

  But output is mixed :

  Stream #0.1(und): Audio: pcm_s16le, 48000 Hz, 1 channels, s16, 768 kb/s
  
  Stream #0.2(und): Audio: pcm_s24le, 48000 Hz, 1 channels, s32, 1152 kb/s

  And shows alert : Incompatible sample format 's32' for codec 'pcm_s16le', auto-selecting format 's16'

  (For XDCAM, it’s necessary to split stereo into dual mono.)

  Command :

  ffmbc -i "$v" -i "$a" -tff -timecode 07:00:00:00 \
  
  -map_audio_channel 1:0:0:0:1:0 \
  
  -map_audio_channel 1:0:1:0:2:0 \
  
  -acodec pcm_s24le -ar 48000 -ac 2 \
  
  -target xdcamhd422 -vtag xd5c -y  -t 1 "$o" \
  
  -acodec pcm_s24le -newaudio
