  • 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" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

    lavu/hwcontext_qsv : make qsv hwdevice works with oneVPL
    

    In oneVPL, MFXLoad() and MFXCreateSession() are required to create a
    workable mfx session[1]

    Add config filters for D3D9/D3D11 session (galinart)

    The default device is changed to d3d11va for oneVPL when both d3d11va
    and dxva2 are enabled on Microsoft Windows

    This is in preparation for oneVPL support

    avutil/intmath : check for ICC before GCC
    

    Intel compiler also defines __GNUC__, so the Intel specific intrinsics were not
    really being used.

  • Frame Accurate Seeking in WebM

    11 janvier 2016, par SapphireSun

    I’m trying to do a somewhat tricky thing with WebM. I am trying to encode a stack of 256 biological images as a WebM. The time dimension of motion is very similar to the space dimension of the image stack so the compression ratios are insanely good. However, I am having trouble decoding the movie frames. I know that WebM uses an IPB predictive coding scheme, but I was reading several blog posts and discussion groups from WHATWG from 2011, and they said that frame accurate seeking was working in Chrome at that time.

    When I do video.currentTime = 0, I correctly get this :

    tissue slice at time zero

    However, if I do video.currentTime = 0.34 (for example) I get something that looks like this :

    enter image description here

    It looks like I’m getting a random poorly predicted frame. Am I just encoding the video wrong ? When I play it normally it looks fine.

    I encoded the video using 256 pngs using ffmpeg compiled with libvpx using the VP8 codec.

    ffmpeg -y -framerate 60 -start_number 0 -pattern_type glob -i '*.png' -qmin 10 -qmax 42 out.webm
