• Evolution #4471 (Nouveau) : singulier_ou_pluriel pour l’arabe

  13 avril 2020, par George Kandalaft

  Voici le filtre singulier_ou_pluriel adapté à l’arabe (qui a plusieurs formes de pluriels suivant le nombre d’objets) :

  <span class="CodeRay"><span class="comment">/**
   * Afficher un message "un truc"/("deux trucs" pour l'arabe)/"N trucs" 
   * Les items sont à indiquer comme pour la fonction _T() sous la forme :
   * "module:chaine" 
   *
   * @param int $nb : le nombre
   * @param string $chaine_un : l'item de langue si $nb vaut un (ou $nb > 10 pour l'arabe)
   * @param string $chaine_plusieurs : l'item de lanque si $nb > 1 ($nb est compris entre 3 et 10 pour l'arabe)
   * @param string $var : La variable à remplacer par $nb dans l'item de langue (facultatif, défaut "nb")
   * @param array $vars : Les autres variables nécessaires aux chaines de langues (facultatif)
   * @return string : la chaine de langue finale en utilisant la fonction _T()

• avformat/mpegtsenc : Fix mpegts_write_pes() for private_stream_2 and other types

  25 avril 2021, par zheng qian

  avformat/mpegtsenc : Fix mpegts_write_pes() for private_stream_2 and other types
  According to the PES packet definition defined in Table 2-17 of ISO_IEC_13818-1
  
  specification, some fields like PTS/DTS or pes_extension could only appears if
  
  the stream_id meets the condition :
  if (stream_id != 0xBC &&  // program_stream_map
  
      stream_id != 0xBE &&  // padding_stream
  
      stream_id != 0xBF &&  // private_stream_2
  
      stream_id != 0xF0 &&  // ECM
  
      stream_id != 0xF1 &&  // EMM
  
      stream_id != 0xFF &&  // program_stream_directory
  
      stream_id != 0xF2 &&  // DSMCC_stream
  
      stream_id != 0xF8)    // ITU-T Rec. H.222.1 type E stream
  And the following stream_id types don't have fields like PTS/DTS :
  else if ( stream_id == program_stream_map
  
  || stream_id == private_stream_2
  
  || stream_id == ECM
  
  || stream_id == EMM
  
  || stream_id == program_stream_directory
  
  || stream_id == DSMCC_stream
  
  || stream_id == ITU-T Rec. H.222.1 type E stream ) 
  
      for (i = 0 ; i < PES_packet_length ; i++) 
  
          PES_packet_data_byte
  
      
  
  
  Current implementation skipped the check of stream_id causing some kind of
  
  streams like private_stream_2 to be incorrectly written with actually a
  
  private_stream_1-like PES header with PTS/DTS field. For example, Japan DTV
  
  transmits news and alerts through ARIB superimpose that utilizes
  
  private_stream_2 still could not be remuxed correctly for now.
  This patch set fixes the remuxing for private_stream_2 and
  
  other stream_id types.

• FFMPEG animation with multiple images

  7 octobre 2015, par user1402732

  I am using ffmpeg command line tool for creating video by mixing images & audio files. Everything is working as expected. Problem started when I need to add some animation to the images when creating videos. i.e. adding zoom in effect to multiple images, it has filters but none of seems to be working with multiple inputs but only for single input.

  Works fine :

  ffmpeg -loop 1 -i Winter.jpg -vf "zoompan=z='min(zoom+0.0015,1.5)':d=125" \
  
  -c:v libx264  -t 5 -s "800x450" zoomin1.mp4

  But this does not :

  ffmpeg -loop 1 -framerate 1 -i bg2.jpg -framerate 1/3 -i img%03d.jpg -i audio.mp3 \
  
  -filter_complex overlay=(W-w)/2:(H-h)/2:shortest=1,format=yuv420p,zoompan=z='zoom+0.095':d=3 \
  
  -c:v libx264 -r 30 -c:a aac -strict experimental -b:a 192k -movflags +faststart \
  
  -shortest testvideo.mp4

  It’s with multiple image and background image & audio.

  It zooms but transition is not smooth and also there’s a gap between images. It should go smoothly one after another.
