  • 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 (...)

  • New BG tile credit, mention of Android 2.3+.

  • Problems video playing in some android devices (version 4+) but not in others

    5 juin 2014, par anquegi

    following the settings for video in android developers, http://developer.android.com/guide/appendix/media-formats.html I encoded a video using ffmpeg like this :

    ffmpeg -i gravityTrailer.mp4 -y -f mp4 -vcodec libx264 -profile:v baseline -acodec aac    -strict -2  -profile:a aac_low -b:v 500k -ar 44100 -b:a 128k -ac 2 -r 30 -s 480x360  output_hq.mp4

    which corresponds on sd highquality in table 2 from android developers (link above).

    Then i put this video in a server and use the class android.media.MediaPlayer to reproduce it from that URL like this

    https://cloudapp.somedomain.com/bmftvideos/output_hq.mp4

    The problem is that the video is played on android version 4+

    you can see the video on :
    LG G2,
    Sony xperia S

    you cannot see the video on :
    Samsung galaxy S4,
    BQ (spanish) aquaris 4.5

    And I don not know why

    this is the ffmpeg output :
