  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • How to reduce latency when streaming x264

    10 janvier 2014, par tobsen

    I would like to produce a zerolatency live video stream and play it in VLC player with as little latency as possible.

    This are the settings I currently use :

    x264_param_default_preset( &m_Params, "veryfast", "zerolatency" );
    

    
m_Params.i_threads              =   2;
    
m_Params.b_sliced_threads       =   true;
    
m_Params.i_width                =   m_SourceWidth;
    
m_Params.i_height               =   m_SourceHeight;
    

    
m_Params.b_intra_refresh        =   1;
    

    
m_Params.b_vfr_input            =   true;
    
m_Params.i_timebase_num         =   1;
    
m_Params.i_timebase_den         =   1000;
    

    
m_Params.i_fps_num              =   1;
    
m_Params.i_fps_den              =   60;
    

    
m_Params.rc.i_vbv_max_bitrate   =   512;
    
m_Params.rc.i_vbv_buffer_size   =   256;
    
m_Params.rc.f_vbv_buffer_init   =   1.1f;
    

    
m_Params.rc.i_rc_method         =   X264_RC_CRF;
    
m_Params.rc.f_rf_constant       =   24;
    
m_Params.rc.f_rf_constant_max   =   35;
    

    
m_Params.b_annexb               =   0;
    
m_Params.b_repeat_headers       =   0;
    
m_Params.b_aud                  =   0;
    

    
x264_param_apply_profile( &m_Params, "high" );

    Using those settings, I have the following issues :

    • VLC shows lots of missing frames (see screenshot, "verloren"). I am not sure if this is an issue.
    • If I set a value <200ms for the network stream delay in VLC, VLC renders a few frames and than stops to decode/render frames.
    • If I set a value >= 200ms for the network stream delay in VLC, everything looks good so far but the latency is, obviously, 200ms, which is too high.

    Question :
    Which settings (x264lib and VLC) should I use in order to encode and stream with as little latency as possible ?

  • ffmpeg works in command line but it doesn't work well in c#

    14 août 2016, par Ahmad Ali Mukashaty

    I want to stream movie via udp so I use this command line and it works well

    ffmpeg -re -i test.mkv -q 1 -vcodec libx264 -f mpegts udp://network:port

    but I want to run this command line using c# like this :

    process = new Process();        
    
process.StartInfo.FileName = "cmd.exe";
    
process.StartInfo.WorkingDirectory = @"c:\FFmpegTool\bin";
    
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    
process.StartInfo.Arguments = "/C ffmpeg.exe";
    
process.Start();
    

    
process.StartInfo.FileName = "ffmpeg";
    
process.StartInfo.Arguments = "-re -i test.mkv -q 1 -vcodec libx264 -f mpegts udp://network:port";
    
process.Start();

    it works but I can’t receive the stream

    why this commnand doesn’t work well when I use it in c# and what’s the different bettwen ranning command in cmd directly or using process class in c#
