• Evolution #2173 : Date de création / publication

  22 septembre 2017, par Julien -

  Ci-dessous, ce que j’ai utilisé sur des objets éditoriaux maison et pour lesquelles j’ai les colonnes suivantes :

  • date_crea (création)
  • date_fpubli (1ere publication)

  Pipeline "pre_insertion" :

  // Fixer la date de création sur certains objets.
  $objets_date_crea = [’spip_butternuts’, ’spip_potimarrons’, ’spip_citrouilles’] ;
  if (in_array($flux[’args’][’table’], $objets_date_crea)) 
      $flux[’data’][’date_crea’] = date(’Y-m-d H-i-s’) ;
  
  

  Pipeline "post_edition" :

  // Changement de statut
  if ($flux[’args’][’action’] == ’instituer’) 
      // Fixer la date de premiere publication sur certains objets.
  
      $objets_date_fpubli = [’spip_butternuts’, ’spip_potimarrons’, ’spip_citrouilles’] ;
  
      if (in_array($flux[’args’][’table’], $objets_date_fpubli)) 
  
          // Si l’objet passe en statut publié.
  
          if ($flux[’data’][’statut’] == ’publie’ and $flux[’args’][’statut_ancien’] != ’publie’) 
  
              // La date de première publication est-elle déjà fixée ?
  
              $table = $flux[’args’][’table’] ;
  
              $primary = id_table_objet($table) ;
  
              $id_objet = intval($flux[’args’][’id_objet’]) ;
              $notFixed = sql_countsel($table, "$primary = $id_objet and date_fpubli like ’0000-00-00%’") ;
  
              // Si non, on la fixe.
  
              if ($notFixed) 
  
                  $flux[’data’][’date_fpubli’] = $flux[’data’][’date’] ;
  
                  $data = array(’date_fpubli’ => $flux[’data’][’date_fpubli’]) ;
  
                  sql_updateq($table, $data, "$primary=$id_objet") ;
  
              
  
          
  
      
  
  
  

• Anomalie #4549 (En cours) : Accessibilité du date picker

  13 septembre 2020, par nicod _

  Je ré-ouvre le ticket pour la notion de format attendu.

  On peut utiliser cette syntaxe pour préciser aux lecteurs d’écran le format de la date, sans qu’il n’apparaisse sur écran :

  <span class="CodeRay"><span class="tag">span> <span class="attribute-name">for</span>=<span class="string"><span class="delimiter">"</span><span class="content">champ_date</span><span class="delimiter">"</span></span><span class="tag">></span>Date<span class="tag"></span>
  
  <span class="tag">span> <span class="attribute-name">hidden</span> <span class="attribute-name">id</span>=<span class="string"><span class="delimiter">"</span><span class="content">date_desc</span><span class="delimiter">"</span></span><span class="tag">></span>Saisir une date sous la forme jj/mm/aaaa<span class="tag"></span>
  
  <span class="tag">span> <span class="attribute-name">type</span>=<span class="string"><span class="delimiter">"</span><span class="content">text</span><span class="delimiter">"</span></span> <span class="attribute-name">id</span>=<span class="string"><span class="delimiter">"</span><span class="content">champ_date</span><span class="delimiter">"</span></span> <span class="attribute-name">name</span>=<span class="string"><span class="delimiter">"</span><span class="content">date</span><span class="delimiter">"</span></span> <span class="attribute-name">aria-describedby</span>=<span class="string"><span class="delimiter">"</span><span class="content">date_desc</span><span class="delimiter">"</span></span><span class="tag">></span>
  
  </span></span></span></span>

• FFMPEG Stream series of pictures over network

  11 septembre 2015, par Commodore63

  I would like to generate video frames on one computer and stream them to another computer to be manipulated and displayed. I want to do this programatically, because the source images are generated from a 3rd party c++ library and on the receiving end I want to manipulate the images before displaying them. I have been pulling my hair out trying FFMPEG. I got the encoding example to work, but am not sure what to do after that. I have just about googled everything i could think of but cannot figure out which FFMPEG library/function to call once I have a stuffed AVPacket. It seems that I need to use either the AVIO or AVFormat or the muxer but it is not clear how to initialize and get them working. I would appreciate any help you could offer.

  To provide some context I have the example ’decoding_encoding.c’ which is provided with ffmpeg working. Here is the spot that I am struggling with :

          /* encode the image */
  
          ret = avcodec_encode_video2(c, &pkt, frame, &got_output);
  
          if (ret < 0) {
  
              fprintf(stderr, "Error encoding frame\n");
  
              exit(1);
  
          }
  
  
  
          if (got_output) {
  
              printf("Write frame %3d (size=%5d)\n", i, pkt.size);
  
              fwrite(pkt.data, 1, pkt.size, f);
  
  
  
              //
  
              // instead of writing to a file, i want to stream to a network
  
              // What do I need to do with pkt to do that?
  
              //
  
              av_free_packet(&pkt);
  
          }

  Most documentation (and the Dranger tutorial) focus on reading and writing files. I do not need to use a file. I want to stream video over a network. It seems like I need AVFormat and AVio but I jsut can’t figure out how they fit together.
