  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.
    The code of this (...)

  • lavu/log,opt : detect setting non-runtime options post-init

    lavu/log,opt : detect setting non-runtime options post-init

    Add a mechanism to AVClass to allow objects to signal their state to
    
generic code. When an object flags itself with the 'initialized' state,
    
print an error (and fail, after the next major bump) if the caller
    
attempts to set non-runtime options.

  • HLS With discontinuity stuck in buffer

    25 mars 2021, par Vittorio Malandrino

    We are using JWPlayer 8.9.0 and we are trying to insert advertisements in our videos.
We are using EXT-X-DISCONTINUITY but apparently, when we get to the point of starting our advertising, the player stops showing a buffer status.

    



    This is an example of our playlist :

    



    #EXTM3U

#EXT-X-MEDIA-SEQUENCE:0

    This is what the JS console tells us :

    



    [log] > audio sampling rate : 48000
9512e6e5-eff6-4f75-806f-a367785315b7:1 [log] > manifest codec:undefined,ADTS data:type:2,sampleingIndex:3[48000Hz],channelConfig:2

9512e6e5-eff6-4f75-806f-a367785315b7:1 [log] > audio sampling rate : 48000

    While the Chrome Media console says :

    



    1.414   kPlay   
{}

17.280  kBufferingStateChanged  
{audio_buffering_state: {reason: "DEMUXER_UNDERFLOW", state: "BUFFERING_HAVE_NOTHING"}}

17.280  kBufferingStateChanged  
{,…}
pipeline_buffering_state: {for_suspended_start: false, reason: "DEMUXER_UNDERFLOW", state: "BUFFERING_HAVE_NOTHING"}
for_suspended_start: false
reason: "DEMUXER_UNDERFLOW"
state: "BUFFERING_HAVE_NOTHING"



    



    Considering that the two videos that we are going to "merge" in the playlist have the same audio / video characteristics (codecs, bitrate, resolution etc.), why is this not working ?
Thank you
