    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • FFMPEG Speed drops and warnings

    31 juillet 2018, par leo_dragons

    I’ve been trying to stream from a BlackMagic DeckLink Mini Recorder to 4 different outputs using FFMPEG, but i get a huge delay let say more than 60 seconds of delay, it takes a long time to buffer on any player and when i check the terminal i get these warnings :

    [decklink @ 0x4655e40] Decklink input buffer overrun!

    I’ve also noticed that i have a very slow capture speed like 0.5x. Here’s the string i use, i’m currently running on CentOS 7.5 :

    ffmpeg -f decklink -i "DeckLink Mini Recorder" -y -pix_fmt yuv420p -vcodec h264 -preset ultrafast -tune zerolatency -b 900k -g 48 -framerate 30 -movflags +faststart -vf scale=1280:720 -bufsize 400k -maxrate 1200k -benchmark -f flv "rtmp ://10.0.0.172:1935/CAMARAS/live9" -vcodec h264 -preset ultrafast -tune zerolatency -b 700k -g 48 -framerate 30 -movflags +faststart -vf scale=854:480 -bufsize 400k -maxrate 1000k -benchmark -f flv "rtmp ://10.0.0.172:1935/CAMARAS/live10" -vcodec h264 -preset ultrafast -tune zerolatency -b 400k -g 48 -framerate 30 -movflags +faststart -vf scale=854:480 -bufsize 400k -maxrate 500k -benchmark -f flv "rtmp ://10.0.0.172:1935/CAMARAS/live11" -vcodec h264 -preset ultrafast -tune zerolatency -b 200k -g 48 -framerate 30 -movflags +faststart -vf scale=640:360 -bufsize 300k -maxrate 300k -benchmark -f flv "rtmp ://10.0.0.172:1935/CAMARAS/live12" > /dev/null 2>&1 &

    But if i run this string alone i get decent capture speed, but i still have an awful latency 30ish seconds :

    ffmpeg -f decklink -i "DeckLink Mini Recorder" -y -pix_fmt yuv420p -vcodec h264 -preset ultrafast -tune zerolatency -b 900k -g 48 -framerate 30 -movflags +faststart -vf scale=1280:720 -bufsize 400k -maxrate 1200k -benchmark -f flv "rtmp ://10.0.0.172:1935/CAMARAS/live9"

    Any help will be highly appreciated.

    Tahnk you.

    Mini amélioration du dateur : pouvoir passer un pas au timepicker car 30min par défaut ça ne convient pas à un paquet de sites à mon avis (tous ceux que je connais qui utilisent Agenda râlent de pas pouvoir caler l’heure d’un événement plus précisément). Tout est pareil par défaut, mais au moins ça se (...)

  • Anomalie #4561 (Nouveau) : Version php min

    30 septembre 2020, par jluc -

    D’après la fonction lister_branches_php_min inclue par spip_loader, spip_loader est prévu pour installer spip 3.1 dont la version php mini est 5.1

    mais spip_loader utilise la syntaxe php avec les crochets pour créer un tableau (ligne 207 : $branch = [ ] ;) qui n’existe que depuis php 5.4
