  • 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 (...)

  • Joining three videos with FFMpeg [duplicate]

    4 novembre 2016, par M. Saez

    This question is an exact duplicate of :

    I’m trying to merge/join three mp4 videos with ffmpeg ; the first one is a 5 seconds intro without an audio track, then it is the main video and at the end there is a 6 seconds mp4 video also without an audio track.

    All videos are encoded with exactly the same settings, so far i’m trying the concat option and i can join them just fine, the problem is the final video doesn’t have the audio track from the main video.

    This is the command i’m using :

    ffmpeg -f concat -i mylist.txt -c copy output.mp4

    Needless to say, the final video must respect the first 5 seconds without audio and the last 6 seconds.

    Any idea ?, if i prefer something where i don’t need to reencode at all, but if i must, i don’t really mind.

    Thanks !

  • avformat/hlsenc : fix handling of delete_segments when %v is present

    avformat/hlsenc : fix handling of delete_segments when %v is present

    When var_stream_map option is used, %v must appear either in segment
    
name template or in the directory path. This latter case currently is
    
not handled and delete_segments flag of hls_flags is broken now. This
    
patch fix this. The root cause of the bug was that HLSSegment struct
    
only stores the final filename part, but not the final directory path.
    
Most of the cases, final path info is unneded, It only necessary when
    
you want to delete old segments (e.g in case of live streaming).
    
Without variant streams it was unnecessary to store the final directory
    
path, because all segment were stored into the same directory. But
    
introducing %v in directory names either require to store the final
    
directory path into HLSSegment or associate segments with their variant
    
streams to be able deleting them later. I have choosen the second
    
solution and introduced a variant index data member into the segment
    
struct.

  • Concatenating image with video for Freeze frame effect

    12 mai 2015, par Code_Ed_Student

    I am currently trying to achieve with ffmepg a freeze frame effect. This is something easy to do with adobe after effects shown here. However I would like to achieve a freeze frame effect(of 5 seconds duration) followed by the 15 second video for the final output video. This should amount to a final duration of 20 seconds. However with the settings below, I am getting a still image with the video following but it does not show a "freeze frame effect". How can I achieve a "freeze frame effect" in ffmpeg ?

    //create image

    ffmpeg -i "/media/test/test.mp4" -ss 00:00:00.023222 -vframes 1 "/media/test/test.png"

    //create freeze image effect

    ffmpeg -i "/media/test/test.mp4" -loop 1 -i "/media/test/test.jpg" -an \
    
-filter_complex "[1:v]trim=start=0:end=5[ol];[0:v]setpts=[nv];[nv][ol]overlay=eof_action=pass[final]" \
    
-map '[final]' -c:a aac -strict experimental -c:v libx264 -q 1 "/media/test/test_effect.mp4"
