Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...) -
HTML5 audio and video support
13 avril 2011, parMediaSPIP 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.

How to achieve 2 pass encoding using x264 ?
6 avril 2017, par Kim Kardashianis there a parameter in the x264_param_t structure
or do I have to send frames to x264 dll twice.. ?
Because I just use encoder_encode function and that returns nal units .
Im guessing it should be a combination of a parameter and using encoder_encode twice.Here is how i initialize params and link to libx264
InitializeSettings(){
x264_param_default_preset(&m_pXParam, "medium", "zerolatency");
x264_param_apply_profile(&m_pXParam, "baseline");
m_pXParam.i_width = cx;
m_pXParam.i_height = cy;
m_pXParam.i_fps_num = fps;
m_pXParam.i_fps_den = 1;
// rate control
m_pXParam.i_keyint_max = fps - 5;
//m_pXParam.rc.f_rf_constant_max = fps + 5;
// rate control
m_pXParam.rc.i_qp_constant=18;
m_pXParam.rc.i_qp_min=18;
m_pXParam.rc.i_qp_max=18;}
x264_picture_alloc(&m_xPicture, X264_CSP_I420 , m_pXParam.i_width, m_pXParam.i_height);
m_xPicture.img = x264img;
m_iframe_size = x264_encoder_encode(m_xEncoder, &m_xNals, &m_iNal, &m_xPicture, &m_xPictureOut);@nobody555 Thanks ! I had another question about x264_param_apply_fastfirstpass function :
/* x264_param_apply_fastfirstpass:
* If first-pass mode is set (rc.b_stat_read == 0, rc.b_stat_write == 1),
* modify the encoder settings to disable options generally not useful on
* the first pass. */what options are they talking about ?
