  • Creating farms of unique websites

    13 April 2011, by

    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" (...)

    movenc: Timecode in MP4 Although MP4 does not have a concrete specification to store timecode information, the following technical note from Apple describes a way to achieve this via timecode track, similar to how it is done for MOV files.

    https://developer.apple.com/library/mac/technotes/tn2174/_index.html
    

    - Enabled creation of timecode tracks for MP4 in the same way as MOV.

    - Used nmhd as media information header of timecode track of MP4 instead
    
  of gmhd used in MOV, thus avoiding tcmi also, as recommended above.

    - Bypassed adding source reference field for MP4, as suggested above.

    qsvenc: store the sync point in heap memory

    The QSV runtime expects the sync point address passed to
    
MFXVideoENCODE_EncodeFrameAsync() to be valid until
    
MFXVideoCORE_SyncOperation().

  • hls: Store first_timestamp in units of AV_TIME_BASE

    29 July 2013, by Martin Storsjö
    hls: Store first_timestamp in units of AV_TIME_BASE

    When first_timestamp was stored as-is, its actual time base
    
wasn’t known later in the seek function.
    

    Additionally, the logic (from 795d9594cfa) for scaling it
    
based on stream_index is flawed - stream_index in the seek
    
function only specifies which stream the seek timestamp refers
    
to, but obviously doesn’t say anything about which stream
    
first_timestamp belongs to.
    

    In the cases where stream_index was >= 0 and all streams had the
    
same time base, this didn’t matter in practice.
    

    Seeking taking first_timestamp into account is problematic
    
when one variant is mpegts (with real timestamps) and one variant
    
is raw ADTS (with timestamps only being accumulated packet
    
duration), where the variants start at totally different timestamps.
