  • 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" (...)

  • Revision 5e766ccee0 : Use rate/distortion thresholds to control non-RD partition search Compare the e

    15 octobre 2014, par Jingning Han

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_speed_features.c



    Use rate/distortion thresholds to control non-RD partition search

    Compare the estimated rate and distortion to the thresholds scaled
    according to the operating block size and determine if further
    split partition search will be run. The compression performance of
    speed -5 is changed by -0.074%. The encoding speed is 10% - 15%
    faster.

  • Converting From 4-bit RAW Audio to WAV (or another output format)

    10 février 2017, par Haravikk

    Okay, so I’ve got some .raw files from an old game (Zork Nemesis) and determined that they’re audio files, however I’m having trouble converting them into something meaningful.

    With a bit of trial and error in Audacity I’ve found that I can listen to a still noisy version of the audio using raw file input settings of 8-bit signed PCM in stereo with a sample rate of 22050hz. However, my suspicion is that the files may in fact be encoded in 4-bits with a sample rate of 44100hz, but I’m having trouble finding a tool that can handle this.

    What I’m looking for is either a tool that can handle 4-bit raw formats, or even a tool that can determine (or guess at) the format of a given .raw file, so I know for sure what I’m dealing with (as I’m just going by trial and error so far).

    I’ve tried sox, but I’m most likely doing something wrong as it complains of an unsupported size :

    sox -r 44100 -e signed -b 4 -c 2 in.raw out.wav

    I was also going to try ffmpeg, but I can’t find the appropriate format/codec to set.

    In case it gives any further clues ; I’ve tried various combinations of settings, increasing sample size while decreasing sample rate increases the (white-)noise, and even 8-bit is still noisy, which is why I’m thinking 4-bit. I’ve tried signed and unsigned, which strangely doesn’t seem to make much of a difference

  • The MOS difference after converting MPEG-2 video to MPEG-4 [closed]

    5 mars 2023, par Parsa Shariat

    Using the application I use, I can calculate MOS for mpeg-4 videos, but not for mpeg-2 videos,
If I convert an MPEG-2 file to MPEG-4 and then determine MOS, is it valid ? If not, how far is it from reality ?
Thanks.
