  • Revision a5e97d874b : VP9_COPY_CONVOLVE_SSE2 optimization This function suffers from a couple problem

    30 juillet 2015, par Scott LaVarnway

    Changed Paths :
     Modify /vpx_dsp/x86/vpx_convolve_copy_sse2.asm



    VP9_COPY_CONVOLVE_SSE2 optimization

    This function suffers from a couple problems in small core(tablets) :
    - The load of the next iteration is blocked by the store of previous iteration
    - 4k aliasing (between future store and older loads)
    - current small core machine are in-order machine and because of it the store
    will spin the rehabQ until the load is finished
    fixed by :
    - prefetching 2 lines ahead
    - unroll copy of 2 rows of block
    - pre-load all xmm regiters before the loop, final stores after the loop
    The function is optimized by :
    copy_convolve_sse2 64x64 - 16%
    copy_convolve_sse2 32x32 - 52%
    copy_convolve_sse2 16x16 - 6%
    copy_convolve_sse2 8x8 - 2.5%
    copy_convolve_sse2 4x4 - 2.7%

  • Amazon Elastic Transcoder vs FFMPEG [closed]

    7 juillet 2017, par KiranD

    I’m developing a website (php based) and there is a provision to upload videos in different formats. I’m using HTML5 player for the front end presentation. So, as the ideal format that is supported by most of the browsers is mp4, I tried using ffmpeg and it works fine.

    I would like to know which transcoder (Amazon Elastic Transcoder or FFMPEG) would be best for handling conversions parallely when there is a huge traffic.

    There could me approximately thousands of users watching the videos and may be hundreds uploading the videos at the same time. I’m using Amazon EC2 for deployment and the traffic is mostly spiky (not flat).

    I’m not sure about the acceptable speed. But, I need the one which can transcode the videos much faster.
