  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

    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%
