  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • avcodec/ac3enc : Deduplicate allocating buffers

    avcodec/ac3enc : Deduplicate allocating buffers

    These allocations only depend upon sizeof(SampleType)
    
(and this size is actually the same for both the fixed-point
    
and the floating-point encoders for most (all supported ?)
    
systems).

  • lavc/audiodsp : RISC-V F vector_clipf

    26 septembre 2022, par Rémi Denis-Courmont
    lavc/audiodsp : RISC-V F vector_clipf

    RV64G supports MIN & MAX instructions natively only on floating point
    
registers, not general purpose ones. The later would require the Zbb
    
extension. Due to that, it is actually faster to perform the clipping
    
"properly" in FPU.
    

    Benchmarks on SiFive U74-MC (courtesy of Shanghai StarFive Tech) :
    
audiodsp.vector_clipf_c : 29551.5
    
audiodsp.vector_clipf_rvf : 17871.0
    

    Also tried unrolling with 2 or 8 elements but it gets worse either way.

  • x86 : checkasm : check for or handle missing cleanup after MMX instructions

    x86 : checkasm : check for or handle missing cleanup after MMX instructions

    Not every asm routine is expected clear the MMX state after returning.
    
It is however a requisite for testing floating point code in checkasm.
    
Annotate functions requiring cleanup with declare_func_emms() and issue
    
emms after the call. The remaining functions are checked for having  a
    
cleared MMX state after return.
