  • 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.

    libavutil/hwcontext_qsv : clean padding when upload qsv frames

    Fix #7830
    
When we upload a frame that is not padded as MSDK requires, we create a
    
new AVFrame to copy data. The frame's padding data is uninitialized so
    
it brings run to run problem. For example, If we run the following
    
command serveral times we will get different outputs.
    

    ffmpeg -init_hw_device qsv=qsv:hw -qsv_device /dev/dri/renderD128 \

    - filter_hw_device qsv -f rawvideo -s 192x200 -pix_fmt p010 \

    - i 192x200_P010.yuv -vf "format=nv12,hwupload=extra_hw_frames=16" \

    - c:v hevc_qsv output.265
    

    According to https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/mediasdk-man.md#encoding-procedures
    
"Note : It is the application's responsibility to fill pixels outside
    
of crop window when it is smaller than frame to be encoded. Especially
    
in cases when crops are not aligned to minimum coding block size (16
    
for AVC, 8 for HEVC and VP9)"
    

    I add a function to fill padding area with border pixel to fix this
    
run2run problem, and also move the new AVFrame to global structure
    
to reduce redundant allocation operation to increase preformance.
