  • Reduce Bandwidth requirement for Video Streaming

    19 février 2014, par user3239282

    Please suggest some points on, how to reduce the bandwidth requirement for a video stream.

    We are actually streaming the desktop across internet, Remote Access Application.

    Encoder : libx264.lib

    Decoder : Ffmpeg

    Codec : H264

    Following is how am configuring h264 for encoding :

        x264_param_default_preset(&this->m_x264Settings, "veryfast", "zerolatency");
    
    this->m_x264Settings.i_threads = 1;
    
    this->m_x264Settings.i_width = width / 2;
    
    this->m_x264Settings.i_height = height / 2;
    
    this->m_x264Settings.i_keyint_max = 10;//fps;
    
    this->m_x264Settings.b_intra_refresh = 1;
    
    this->m_x264Settings.i_fps_num = 10;
    
    this->m_x264Settings.i_fps_den = 1;
    
    // Intra refres:
    
    this->m_x264Settings.i_keyint_max = 25;
    
    this->m_x264Settings.b_intra_refresh = 1;
    
    //Rate control:
    
    this->m_x264Settings.rc.i_rc_method = X264_RC_CRF;
    
    this->m_x264Settings.rc.f_rf_constant = 25;
    
    this->m_x264Settings.rc.f_rf_constant_max = 35;
    

    
    //For streaming:
    
    this->m_x264Settings.b_repeat_headers = 1;
    
    this->m_x264Settings.b_annexb = 1;
    
    x264_param_apply_profile(&this->m_x264Settings, "baseline");
    

    
    this->m_width = width;
    
    this->m_height = height;
    
    this->m_encoder = x264_encoder_open(&this->m_x264Settings);
    
    x264_picture_alloc(&this->m_picIn,X264_CSP_I420,(width / 2),(height / 2));
    
    int sws_flags = SWS_BICUBIC;
    
    m_imgConverCtx = sws_getContext(width, height, PIX_FMT_RGB32, (width/2), (height/2), PIX_FMT_YUV420P,sws_flags, NULL, NULL, NULL);

    Thanks in advance,
    Paul.
