• ERROR : libvpx decoder version must be >=0.9.1 [install ffmpeg in CentOS 6.3]

  4 septembre 2017, par Hu Le

  I want to install ffmpeg in CentOS 6.3
  It needs to install libvpx.

  I install libvpx before. Its version is 0.9.7.

  When I install ffmpeg, it indicates :

  [root@hostname ffmpeg]# PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure —prefix="$HOME/ffmpeg_build" —extra-cflags="-I$HOME/ffmpeg_build/include" —extra-ldflags="-L$HOME/ffmpeg_build/lib -ldl" —bindir="$HOME/bin" —pkg-config-flags="—static" —enable-gpl —enable-nonfree —enable-libfdk_aac —enable-libfreetype —enable-libmp3lame —enable-libopus —enable-libvorbis —enable-libvpx —enable-libx264 —enable-libx265

  ERROR: libvpx decoder version must be >=0.9.1

  If you think to configure made a mistake, make sure you are using the latest
  version from Git. If the latest version fails, report the problem to the
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  Include the log file "ffbuild/config.log" produced by configuring as this will help
  solve the problem.

  Now my rpm and yum is :

  [root@hostname ]# yum list libvpx

  Loaded plugins : fastestmirror

  • nux-dextop : li.nux.ro

  • rpmforge : mirrors.neusoft.edu.cn

  libvpx.x86_64 1.3.0-5.el6_5 installed

  Available Packages

  libvpx.i686 0.9.7.1-3.el6.nux nux-dextop

  I want to remove libvpx.i686 in this way :

  [root@hostname ffmpeg]# yum remove libvpx.i686

  Loaded plugins : fastestmirror

  Setting up Remove Process

  No Match for argument : libvpx.i686

  • nux-dextop : li.nux.ro

  • rpmforge : mirrors.neusoft.edu.cn

  Package(s) libvpx.i686 available, but not installed.

  No Packages marked for removal

  How to remove libvpx.i686 completely ?

• declaration of referenced constant is not found in built-in library and project files

  2 août 2016, par Auguste Larrivé

  Hello on the server I’m working on a directory named home.
  In an other directory there’s the library ffmpeg.

  Now I’m trying to use ffmpeg in my "home" directory with php.

  This is my code line :

  <?php ffmpeg -f image2 -i image%d.jpg  video.mpg ?>

  I know "<" is missing. It is on my PHPstorm codeline.

  Unfortunately I can read an error which said declaration of referenced constant is not found in built-in library and project files about ffmpeg.
  Does anyone now anything about this ?

• 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.
