  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Use, discuss, criticize

    13 avril 2011, par

    Talk to people directly involved in MediaSPIP’s development, or to people around you who could use MediaSPIP to share, enhance or develop their creative projects.
    The bigger the community, the more MediaSPIP’s potential will be explored and the faster the software will evolve.
    A discussion list is available for all exchanges between users.

    despite solving the problem, I'd be happy with any other solution to compress video to pal-dvd or pal-vcd standard

    


    I tried re-encoding a mpeg-2 video using avconv and/or ffmpeg to target pal-dvd or pal-vcd or even just vcd or dvd.
manpage states option -target as main option :

    


    

        -target type (output)


    


    Specify target file type ("vcd", "svcd", "dvd", "dv", "dv50"). type may be prefixed with "pal-", "ntsc-" or "film-" to use the corresponding standard. All the format options
(bitrate, codecs, buffer sizes) are then set automatically. You can just type :

    


    avconv -i myfile.avi -target vcd /tmp/vcd.mpg

    


    Nevertheless you can specify additional options as long as you know they do not conflict with the standard, as in :

    


    avconv -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg

    


    


  • ffmpeg : how to prevent wait in case of error

    14 février, par xrfang

    I use ffmpeg to add watermark to images/videos, using the following command line :

    


    ffmpeg -y -f mjpeg -i input -i /tmp/watermark.png -filter_complex "..." -f mjpeg output


    


    The problem is, in case the input file is not a jpeg file, the process will HANG instead of quit with an error :

    


    Press [q] to stop, [?] for help
[mjpeg @ 0x126dc60] dqt: len 28602 is too large
Error while decoding stream #0:0: Invalid data found when processing input
frame=    0 fps=0.0 q=0.0 size=       0kB time=-577014:32:22.77 bitrate=  -0.0kbits/s speed=N/A


    


    In my situation, the file has no extension, and I have to specify -f. In case I got the file type wrong, it is an acceptable bug, which I can fix as soon as I found such problem. However it is not good for me if ffmpeg hangs without returning to the parent process, because I have a very large queue of files to process, and I don't want any bug to block the processing task.

    


  • Revision df90d58f4f : Speed up motion estimation using small partitions' result(experiment) Current p

    3 juillet 2013, par Yunqing Wang

    Changed Paths :
     Modify /vp9/encoder/vp9_block.h


     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h


     Modify /vp9/encoder/vp9_rdopt.c



    Speed up motion estimation using small partitions' result(experiment)

    Current partition checking starts from small sizes, and then goes up
    to large sizes. This experiment uses the small partitions' motion
    estimation result, which is already available, to speed up the
    large partition's motion estimation. We can decide to skip some
    patition checkings if they are unlikely choices. We could use the
    motion vector(MV) result as current partition's prediction MV, limit
    the search range and reference frame.

    Current result at speed 1 :
    psnr loss : 1.19% for stdhd, 0.287% for derf.
    speed gain : 14% for sunflower(hd), 11% for akiyo.

    Further improvement will be done later.
