    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.

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • armv6 : Accelerate ff_imdct_half for general case (mdct_bits != 6)

    armv6 : Accelerate ff_imdct_half for general case (mdct_bits != 6)

    The previous implementation targeted DTS Coherent Acoustics, which only
    
requires mdct_bits == 6. This relatively small size lent itself to
    
unrolling the loops a small number of times, and encoding offsets
    
calculated at assembly time within the load/store instructions of each
    
iteration.
    

    In the more general case (codecs such as AAC and AC3) much larger arrays
    
are used - mdct_bits == [8, 9, 11]. The old method does not scale for
    
these cases, so more integer registers are used with non-unrolled versions
    
of the loops (and with some stack spillage). The postrotation filter loop
    
is still unrolled by a factor of 2 to permit the double-buffering of some
    
VFP registers to facilitate overlap of neighbouring iterations.
    

    I benchmarked the result by measuring the number of gperftools samples
    
that hit anywhere in the AAC decoder (starting from aac_decode_frame())
    
or specifically in ff_imdct_half_c / ff_imdct_half_vfp, for the same
    
example AAC stream :
    

                      Before          After
    
                  Mean   StdDev   Mean   StdDev  Confidence  Change
    
aac_decode_frame  2368.1 35.8     2117.2 35.3    100.0%      +11.8%
    
ff_imdct_half_*   457.5  22.4     251.2  16.2    100.0%      +82.1%
