  • Emballe médias : à quoi cela sert ?

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

    Change the use of a reserved color space entry

    This commit rename a reserved color space entry to BT_2020, it intends
    to provide support for VP9 bitstream to pass along the color space
    type defined in BT.2020(Rec.2020)

    please note this entry does not have any effect on encoding/decoding
    behavior, but allow applications to the pass the information along
    from encoding end to decoding end.

  • Revision 5215b83aea : Simplifying and inlining k_cvtlo_epi16 and k_cvthi_epi16 Simplify the k_cvtlo_e

    3 octobre 2013, par A.Mahfoodh

    Changed Paths :
     Modify /vp9/encoder/x86/vp9_dct32x32_sse2.c



    Simplifying and inlining k_cvtlo_epi16 and k_cvthi_epi16

    Simplify the k_cvtlo_epi16 and k_cvthi_epi16 to only two
    instructions. Then inlined them.

    quoting from intel MMX_App_Compute_16bit_Vector.pdf‎
    "The PMADDWD instruction multiplies four
    pairs of 16-bit numbers and produces partial sums of the results
    and can do so once per clock (with a three-clock latency)."
    so I am assuming that there will be three clock overhead after the
    last _mm_madd_pi16 command.
    Even with the overhead the number of clocks in general should be
    smaller. I am not sure though becasue I could not find information
    about number of clocks required for instructions in k_cvtlo_epi16
    and k_cvthi_epi16. I will run a test and compare the execution time.
