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-KIT - Video is cut after adding 2 watermarks
7 août 2023, par dfjickI made a FFMPEG-KIT command to add 2 PNG watermarks to the video and everything went smoothly.


String ffmpegCommand = "-y -i " + videoPath +
 " -i " + watermarkImagePath +
 " -i " + userID +
 " -filter_complex " +
 "\"[0:v][1:v]overlay=x='if(lt(mod(t,10),5),10,W-w-10)':y='if(lt(mod(t,10),5),10,H-h-35)',\"" +
 "\"overlay=x='if(lt(mod(t,10),5),7,W-w-7)':y='if(lt(mod(t,10),5),165,H-h-15)'[out]\"" +
 " -map [out] -map 0:a -c:v libx264 -crf 18 -preset slow -c:a aac " + outputPath;


But for videos that are longer than 20 seconds, the results don't match the original video, sometimes the videos are only <20 seconds and at random times.


but i got this error, do you guys know how to fix it ?

I've tried to use this
-fflags +discardcorrupt, but the result is still the same. the duration of the video that has been watermarked does not match the original video

FFmpeg crashing on drawtext filter (ffmpeg-python)
31 août 2023, par DeadSecHey guys so im trying to use ffmpeg-python to add text to a video but its crashing at


[Parsed_drawtext_0 @ 0000012ea115ee80] Setting 'text' to value 'hi'

and I'm not sure what I can do to fix this problem. I tried pure FFmpeg command-line style and still the same issue where it gets stuck at
Setting text to valueand it simply outputs a 0byte mp4 after crashing.

My code :


os.environ['FONTCONFIG_FILE'] = r'C:\Users\NOP\NOP\NOP\NOP\binaries\fonts\fonts.conf'
 os.environ['FONTCONFIG_PATH'] = r'C:\Users\NOP\NOP\NOP\NOP\binaries\fonts'
 os.environ['FC_CONFIG_DIR'] = r'C:\Users\NOP\NOP\NOP\NOP\binaries\fonts'
 in_ = ffmpeg.input(output_video_logo)
 in_ = in_.drawtext(text='hi')
 ffmpeg.output(in_, output_video).global_args('-loglevel', 'debug').run(cmd=FFMPEG_PATH)


Font config file :


<?xml version="1.0"?>


<fontconfig>





 <dir>WINDOWSFONTDIR</dir>
 <dir>~/fonts</dir>
 <dir prefix="cwd">.</dir>
 <dir>~/.fonts</dir>


 <match target="pattern">
 <test qual="any">
 <string>mono</string>
 </test>
 <edit mode="assign">
 <string>monospace</string>
 </edit>
 </match>


 <match target="pattern">
 <test qual="any">
 <string>sans serif</string>
 </test>
 <edit mode="assign">
 <string>sans-serif</string>
 </edit>
 </match>


 <match target="pattern">
 <test qual="any">
 <string>sans</string>
 </test>
 <edit mode="assign">
 <string>sans-serif</string>
 </edit>
 </match>


 <include>conf.d</include>



 <cachedir>WINDOWSTEMPDIR_FONTCONFIG_CACHE</cachedir>
 <cachedir>~/.fontconfig</cachedir>

 <config>


 <rescan>
 <int>30</int>
 </rescan>
 </config>

</fontconfig>


Is this a issue with any of my fontconfig or script ? I'm really lost on fixing this.


As requested by Rotem tried adding new input to drawtext and this was the output before crashing with no error message :
