  • avcodec/bitpacked_dec : optimize bitpacked_decode_yuv422p10

    5 mai 2023, par Devin Heitmueller
    avcodec/bitpacked_dec : optimize bitpacked_decode_yuv422p10

    Rework the code a bit to speed up the 10-bit bitpacked decoding
    
routine.  This is probably about as fast as I can get it without
    
switching to assembly language.
    

    Demonstratable with :
    

    ./ffmpeg -f lavfi -i "smptehdbars=size=3840x2160" -c bitpacked -f image2 -frames:v 1 source.yuv
    
./ffmpeg -f bitpacked -pix_fmt yuv422p10le -s 3840x2160 -c:v bitpacked -i source.yuv -pix_fmt yuv422p10le out.yuv
    

    On my development system, it went from 80ms for a 2160p frame
    
down to 20ms (i.e. a 4X speedup).  Good enough for now, I hope...
    

    Comments from Marton :
    

    Originally on my system better performance could be achieved by simply
    
switching to the cached bitstream reader, but for Devin it was slower than
    
his direct byte operations.
    

    I changed the order of writing output from u/y/v/y to u/v/y/y, and that made
    
the code faster than the cached bitstream reader on my system as well.
    

    TIMER measurement of the decode loop on Ryzen 5 3600 with command line :
    

    ./ffmpeg -stream_loop 256 -threads 1 -f bitpacked -pix_fmt yuv422p10le -s 3840x2160 -c:v bitpacked -i source.yuv -pix_fmt yuv422p10le -f null none -loglevel error
    

    Before : 823204127 decicycles in YUV,     256 runs,      0 skips
    
After :  315070524 decicycles in YUV,     256 runs,      0 skips
