1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)

Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...) -

Merging two mp4 videos using ffmpeg
12 novembre 2018, par kristian zivkovicI 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.mp4The 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.

Unable to Record Video in Jenkins using ffmpeg in Windows System
12 novembre 2018, par Deepak Kumar SusarlaI 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.

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.
