• Anomalie #4012 : pipeline post_insertion n’affiche pas toutes les valeurs insérées

  9 octobre 2017, par Peet du

  ok ok !

  Donc lors de la création d’une nouvelle instance d’un objet, SPIP fait les choses en deux temps.

  1er temps¶

  objet_inserer() va ’préparer’ la nouvelle instance et tenter, si les champs existent dans l’objet, d’enregistrer les valeurs de :
  

  [’id_rubrique’]
  [’id_secteur’]
  [’lang’]
  [’langue_choisie’]
  [’statut’]
  [’date’]
  

  Donc au mieux le pipeline post_insertion renvoi un tableau contenant l’id de l’objet + le tableau des champs ci-dessus et leurs valeurs.

  2e temps¶

  si objet_inserer() renvoie bien un id_objet, objet_modifier() va lui enregistrer le reste, c’est à dire les valeurs correspondants aux champs déclarés comme editables dans plugins/base/mon_objet.php

  Il faut donc utiliser le pipeline post_edition si on veut pouvoir lire une des valeurs dites "editables".

  Donc pas d’anomalie, juste une incompréhension de la doc.

  On peut fermer le ticket
  ps : merci marcimat et jluc

• Possible to Combine Live m3u8 stream with PIP overlay from WebRTC source ?

  25 octobre 2015, par user1258530

  Can someone tell me what server-side technology (perhaps ffmpeg), one could use in order to :

  1) display this full-screen live-streaming video :

  http://aolhdshls-lh.akamaihd.net/i/gould_1@134793/master.m3u8

  2) and overlay it in the lower-right corner with a live video coming from a webRTC video-chat stream ?

  3) and send that combined stream into a new m3u8 live-stream

  4) Note that it needs to be a server-side solution - - - cannot launch multiple video players in this case (needs to pass the resulting stream to SmartTV’s which only have one video-decoder at a time)

  The closest example I’ve found so far is this article :

  https://trac.ffmpeg.org/wiki/Create%20a%20mosaic%20out%20of%20several%20input%20videos

  Which isn’t really live, nor is it really doing overlays.

  any advice is greatly appreciated.

• ffmpeg split video H264 stutters on Windows Media Player

  9 mars 2019, par Juan Foegen

  I am converting and splitting wmv and mp4 into new mp4 files. I am using ffmpeg to do the conversion with simply :
  ffmpeg -i inputfile.wmv -vcodec libx264 -ss 00:00:10 -t 00:00:15 outputfile.mp4

  So when I create my split video it plays fine on other video players, like VLC, but stutters when initially playing on Windows Media Player and even shows a blank screen for a moment and then after about 5 seconds, the video will play normally. If I then select play again without reloading, Windows Media Player will play the video fine, with no stuttering.

  If I REMOVE the start parameter when doing the conversion, then the resulting video will play without issues on all my players, INCLUDING Windows Media Player.

  I have tried changing the frame rate, the bit rate and altered different optimization options mentioned here - https://trac.ffmpeg.org/wiki/Encode/H.264

  I need the split video to play on Windows machines on Windows Media Player and on the web streamed using the video element. This is why I chose H264 codec and MP4.

  Has anyone had issues playing ffmpeg split videos using H264 codec with Windows Media Player ? I am using the latest version of ffmpeg. Anyone have any other suggestions on any different settings I could try to adjust ?

  Thanks
