• Evolution #4281 : Extension du critère secteur (à l’id_groupe en plus de l’id_rubrique)

  13 février 2019, par Naema *

  Merci tcharlss pour cette réponse,
  qui plus est, est beaucoup moins désagréable que la précédente. Mon message
  est une suggestion, et je vais de mon côté me renseigner sur cette API et
  ce plugin "déclarer parents". Merci.

  Cordialement

  La demande #4281 <https://core.spip.net/issues/4281#change-14733> a été
  mise à jour par tcharlss (*´_ゝ｀).

  Avec l’API de déclaration des parents qui est en test dans le plugin « 
  déclarer parents », il est envisageable d’avoir un critère générique qui
  marche sur tous les types d’objets.
  Un critère racine par exemple.

  Bonjour,
  une simple suggestion (et mes excuses si c’est déjà effectué ou sur les
  rails) : le secteur est actuellement la rubrique racine de l’objet, ce qui
  permet de shunter toute l’arborescence hiérarchique et de définir finement
  les critères d’affichage d’une boucle sans se préoccuper de la hiérarchie
  intermédiaire. C’est un excellent système et je me demande s’il est
  possible de l’étendre à la notion de id_groupe, pour les objets éditoriaux
  qui ne sont pas reliés à des rubriques (comme par ex. les auteurs, ou à un
  autre objet éditorial créé de novo). On peut bien sûr utiliser
  l’id_parent pour affiner aussi, mais dans le cas où l’id_parent est
  attribué au groupe et non à l’objet lui-même, il manque juste une petite
  solution. Merci !

• ffmpeg -Video live feed

  22 juin 2019, par Rajeev

  I am using AMCREST security camera at my home. My objective is to get a live feed one of IP camera attached to my NVR to a webportal using rtsp ://My environment is Raspberry pi.

  I am able to successfully start the ffserver but conversion is failing when I am trying pass the input video and stream it to video.ffm

  I have tried various combination of parameters in the command but the below one seems to be very close where I got only one error ( av_interleaved_write_frame() : Connection reset by peer)

  $ffmpeg  -thread_queue_size 800  -i "rtsp://home:Home1234@192.168.1.32:554/cam/realmonitor?channel=4&subtype=0" -f lavfi -i aevalsrc=0  http://127.0.0.1:8090/video.ffm

  My expectation is that ffmpeg will start writing data to video.ffm located in /tmp directory so that I can read the data from our browser or vlc media player by just entering the following link
  http://localhost:8090/stream

  ****** Update after 2 hr******

  I made slight change to the command parameter and my out changed as well.What it looks like the temporary video file that got generated in /tmp folder is not getting consumes by video.ffm ( I may be wrong in my analysis)
