Les tâches Cron régulières de la ferme
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)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. 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 (...)

FFmpeg adding 0.05 seconds of silence to transcoded AAC file ?
29 octobre 2015, par FTLRalphIn Java, I’m using FFmpeg to convert a WAV file to AAC with the function :
-i input.wav -ac 1 -ab 64000 -ar 22050 output.aacWhen I open these two files in Audacity, I can clearly see that the AAC file is 0.05 seconds longer, with 0.05 seconds of silence added to the beginning.
This is an issue when I try to mux this AAC file with a video file - the audio doesn’t sync up.
Is there some sort of parameter to prevent this behavior or another way to get around this issue ?
Edit - Console output while running the function :

FFMPEG gets stuck on higher resolution or frame rate [H265]
29 octobre 2015, par AnakooterI am running the following command which works perfectly on my system running Elementary OS on Intel Corei5 :
ffmpeg -f v4l2 -i /dev/video0 -c:v libx265 -x265-params crf=14:vbv-maxrate=128:vbv-bufsize=32:keyint=10:qcomp=0.5:rd=5:ctu=64:min-cu-size=8:cu-lossless=false:fast-intra=false:strong-intra-smoothing=false -tune zerolatency -s 640x480 -preset ultrafast -r 5 -pix_fmt yuv420p -an -strict experimental -f mpegts udp://239.0.0.1:5002but if I change the output size to 800x600 and or increase the frame rate from 5 to 10. After a few seconds the video gets stuck.
I have monitored the CPU usage for both the commands and it is almost identical that is between 300 to 400 percent ( since 4 cores ).
Any possible answers to mitigate the issue.

ffmpeg command failed
25 octobre 2015, par Asad kamranI am experimenting FFMPEG command to convert any video format to mp4.
Server admin execute the below command created by me and show me the errors :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpgThis is error :
[aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
codecs are not enabled, add ’-strict -2’ if you want to use it.how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.
my ffmpeg and server are as follow :

developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-16)EDIT 1 :
I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :New command :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpgAfter executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
