  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • FFMPEG hangs (sometimes) when trying to take a photo from USB camera ?

    13 mai 2022, par dezman

    I am attempting to write a script that takes a photo every 3 seconds from camera source "1", the -pix_fmt I think is unique to my USB camera.

    


    Here is the script :

    


    #!/bin/bash

set -e

while :
do
  nice_num=$(date +%s)
  
  ffmpeg -ss 00:00:00 -f avfoundation -pix_fmt yuyv422 -r 30.000030 -i "1" -t 1 -frames:v 1 -q:v 2 "image_$nice_num_%03d.jpg"
  
  wait

  sleep 3
done


    


    The issue is half the time it successfully takes the photo, and half the time it just hangs forever echoing this (not useful) :

    Then I CTRL-C 3 times and get :

    Other methods of "taking a photo every n seconds from bash" are also appreciated.

  • Restreaming HLS video source to RTMP using ffmpeg.autogen

    23 juin 2021, par Andrew Wilcockson

    I am trying to write a C# restreaming class that will take HLS/m3u8 H264 encoded video streams and restream them as RTMP H264 encoded video.&#xA;I started with the simple transport stream recorder sample and was able to make it work in the following scenarios :&#xA;UDP restreamed to UDP (mpegts)&#xA;UDP restreamed to RTMP (flv)&#xA;HLS restreamed to UDP (mpegts)&#xA;But cannot for the life of me get it to work with HLS to RTMP.&#xA;I get a failure return code of -22 on my call to avformat_write_header&#xA;Note that I can make this work perfectly from the command line version of ffmpeg with the following command :&#xA;ffmpeg -i http://rbmn-live.akamaized.net/hls/live/590964/BoRB-AT/master_1660.m3u8 -vcodec libx264 -f flv rtmp://rtmpserver/streamname
