  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • 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 :

  • ffmpeg conversion from Flac to Ogg produces corrupted files

    8 avril 2021, par experimental

    i transcoded flac files to ogg using this command

    


    ffmpeg -i input.flac -c:a libvorbis -b:a 500k  output.ogg


    


    yes i use 500k to keep the highest quality possible, some of the files are ok, but some of them can not be played - Unsupported format or corrupted file says the foobar - also my icecast streamer cant read it. So there is something wrong with the files.

    


    I believed it was due to the high bitrate so I tried

    


    ffmpeg -i input.flac -c:a libvorbis -b:a 320k  output.ogg


    


    the same happened, some files were ok, some were not playable.
so I tried again with default using this command

    


    ffmpeg -i input.flac -c:a libvorbis output.ogg


    


    same thing. some files were ok, some were corrupted and not playable.

    


    i have no clue why.

    


    both flac and ogg are in the same family, what happened during the transcoding that it became a corrupted file ?

    


    the spectral analysis does not show anything wrong - here it the ogg https://prnt.sc/115zdjl, here is the original flac https://prnt.sc/115zegw

    


    i am really interested what is going on and how to make it work ?

    


    can anyone explain ?

    


    here is complete log
