  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

    PHP et safe_mode activé
    Une des principales sources de problèmes relève de la configuration de PHP et notamment de l’activation du safe_mode
    La solution consiterait à soit désactiver le safe_mode soit placer le script dans un répertoire accessible par apache pour le site

  • avcodec/omx : Fix handling of fragmented buffers

    avcodec/omx : Fix handling of fragmented buffers

    See https://trac.ffmpeg.org/ticket/7687
    

    If an encoded frame is returned split over two or more
    
IL buffers due to the size, then there is a race between
    
whether get_buffer will fail, return NULL, and a truncated
    
frame is passed on, or IL will return the remaining part
    
of the encoded frame.
    
If get_buffer returns NULL, part of the frame is left behind
    
in the codec, and will be collected on the next call. That
    
then leaves a frame stuck in the codec. Repeat enough times
    
and the codec FIFO is full, and the pipeline stalls.
    

    A performance improvement in the Raspberry Pi firmware means
    
that the timing has changed, and now frequently drops into the
    
case where get_buffer returns NULL.
    

    Add code such that should a buffer be received without
    
OMX_BUFFERFLAG_ENDOFFRAME that get_buffer is called with wait
    
set, so we wait for the remainder of the frame.
    
This code has been made conditional on the Pi build in case
    
other IL implementations don't handle ENDOFFRAME correctly.

  • ANSI Code Coverage Followup

    9 mars 2012, par Multimedia Mike — Programming

    The people behind sixteencolors.net noticed my code coverage project concerning the ANSI video decoder and asked what they could do to help. I had already downloaded 350 / 4000 of their artpacks but didn’t want to download the remainder if I could avoid it. They offered to run my tool against their local collection of files.

    Aside : They have all of the artpacks archived at Github.

    The full corpus of nearly 4000 artpacks contains over 146,000 files. Versus my sampling of 350 artpacks and 13,000 files that covered all but 45 lines of the ansi.c source file, the full corpus has files to exercise… 6 more of those lines. Whee. This means that there are files which exercise the reverse and concealed attributes, all 3 “erase in line” modes, and one more error path (which probably wasn’t a valid file anyway).

    Missing features mostly cluster around different video modes, including : 320×200 (25 rows), 640×200 (25 rows), 640×350 (43 rows), and 640×480 (60 rows) ; on the plus side, nothing tripped the “unsupported screen mode” case. There are no files that switch modes during playback.

    I guess statistical sampling theory holds out here– a small set of randomly chosen files would do a fine job covering code. But this experiment is about finding the statistical outliers.
