  • 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 (...)

    despite solving the problem, I'd be happy with any other solution to compress video to pal-dvd or pal-vcd standard

    


    I tried re-encoding a mpeg-2 video using avconv and/or ffmpeg to target pal-dvd or pal-vcd or even just vcd or dvd.
manpage states option -target as main option :

    


    

        -target type (output)


    


    Specify target file type ("vcd", "svcd", "dvd", "dv", "dv50"). type may be prefixed with "pal-", "ntsc-" or "film-" to use the corresponding standard. All the format options
(bitrate, codecs, buffer sizes) are then set automatically. You can just type :

    


    avconv -i myfile.avi -target vcd /tmp/vcd.mpg

    


    Nevertheless you can specify additional options as long as you know they do not conflict with the standard, as in :

    


    avconv -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg

    


    


  • Xubuntu ffmpeg screen capturing very slow when no display connected

    8 décembre 2022, par fre_der

    I use ffmpeg on an Intel Nuc with Xubuntu 22.04 (XFCE4, lightdm), with x11grab for screen capturing the desktop, and sending output to a multicast UDP stream (which is shown on different IPTV sets in the network).
The system uses autologin, and autostarts Firefox in kiosk mode, rendering a html5 video.

    


    Everything works fine when a display is attached, but from the moment the hdmi cable is detached, the output video is extremely slow (very shaky, looks like 1 fps, audio is OK although it has occasional hickups).

    


    CPU and memory usage doesn't seem to be affected whether a display is attached or not.

    


    This runs fine on Xubuntu 18.04, although there might be small config changes that I'm not aware of.

    


    To be able to display output when no display is attached, I created a VIRTUAL1 display :

    


    xrandr -d :0 --verbose --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr -d :0 --verbose --addmode VIRTUAL1 "1920x1080_60.00"


    


    my /usr/share/X11/xorg.conf.d/20-intel.conf looks like :

    


    Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "VirtualHeads" "1"
  Option "TearFree" "true"
  Option "TripleBuffer" "true"
  Option "DRI" "false"
EndSection


    


    The ffmpeg command :

    


    ffmpeg -r 25 -thread_queue_size 512 -f x11grab -s 1920x1080 -i :0 -thread_queue_size 512 -f alsa -i default -c:a mp2 -f mpegts udp://239.255.255.8:50000?pkt_size=1316


    


    (during trial/error I tested various ffmpeg command line options to no avail)

  • FFMEPG crop : Invalid too big or non positive size for width '1920' or height '1040'

    12 février 2021, par NatePhysics

    I run into a strange issue with a particular file in FFMPEG. When I try and crop it down a little I get :

    


    [Parsed_crop_0 @ 000002ad60c27980] Invalid too big or non positive size for width '1920' or height '1040'
[Parsed_crop_0 @ 000002ad60c27980] Failed to configure input pad on Parsed_crop_0
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:37
Conversion failed!


    


    This is odd to me because you can even see from the stream metadata that the resolution is much higher :

    


    Metadata:
    encoder         : libebml v1.4.0 + libmatroska v1.6.2
    creation_time   : 2021-02-09T22:45:47.000000Z
  Duration: 02:17:48.93, start: 0.000000, bitrate: 8548 kb/s
    Stream #0:0: Video: h264 (High), yuv420p(progressive), **1920x1080** [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)


    


    There's only 1 video stream. I'm running the following command :

    


    ffmpeg -i "wedding.mkv" -filter:v "crop=1920:1040" -c:v libx264 -preset slow -tune film -profile:v high -level 4.1 -crf 19 -c:a copy -c:s copy -map 0 "wedding-cropped.mkv"


    


    I can preview the crop using the following command without any errors :

    


    ffplay -i "wedding.mkv" -vf "crop=1920:960"


    


    I've cropped a few files before without issue. I'm a bit confused as to why I'm getting a resolution error in this case when the video file is clearly higher resolution. I've also tested lowering the cropped resolution and even when I lower both by several hundred pixels it still spits out the same error. Any thoughts or suggestions ?
