  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La 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 h264_nvencCompressed Video could not slice

    6 mars 2020, par Zac Liu

    I am currently using ffmpeg to compress video and videos can be played normally after compressing. However, when I tried to slice the video through nimble streamer, each chunk duration is at least 8 secs, even though I set the target chunk duration is 2 secs. This leads to the problem that loading each video chunk takes even longer comparing with the original video.

    Compression command I used :

    ffmpeg -y -hwaccel cuvid -c:v h264_cuvid -i input.mp4 -c:v h264_nvenc output.mp4

    and

    ffmpeg  -i input.mp4 -c:v h264_nvenc output.mp4

  • ffmpeg crashes as file is in use

    11 mai 2017, par Jake

    Recently whilst working inside of FFMPEG ive been trying to run a script which shows the current artist based on what a textfile says the current artist is. Loading this every frame, however the file is also being written to and thus when being written to the stream crashes with..

    The text file 'artist.txt' could not be read or is empty
    
Error while filtering
    
Failed to inject frame into filter network: Invalid argument

    The line im using to write the artist.txt into the content is as follows..

    -vf "drawtext=enable='gte(t,3)':fontfile=fonts/Dosis-Bold.ttf:textfile=artist.txt:reload=1:y=h-line_h-10:x=(W/tw)*n"

    ( yes this code is stolen from an example )

    Can anyone help ?

  • transcode segment files without stutter for http live streaming

    28 juillet 2015, par zerocap

    I segmented a multicast video stream into small ts files for my HTTP live streaming service and it worked quite well. Then I found the bitrate of the source was too high (1.5mbps) so I set up a background job to transcode the ts files to a smaller bitrate (500kbps) using FFmpeg. The problem is that the 500k .m3u8 playback stutters(on every new file’s loading) and is not as smooth as the 1.5mbps one.

    My transcoding command line is like following :

    ffmpeg -i /home/rca/tst.ts -f mpegts -acodec libmp3lame -ar 48000 -ab 64k -vcodec libx264 -b 500k /home/rca/tst.ts

    Any ideas for this ? Thank you !
