  • opusdsp : adjust and optimize C function to match assembly

    opusdsp : adjust and optimize C function to match assembly
    

    The C and asm versions behaved differently _outside_ of the codec.

    The C version returned pre-multiplied 'state' for the next execution
    to use right away, while the assembly version outputted non-multiplied
    'state' for the next execution to multiply to save instructions.
    Since the initial state when initialized or seeking is always 0,
    and since C and asm versions were never mixed, there was no issue.

    However, comparing outputs directly in checkasm doesn't work without
    dividing the initial state by CELT_EMPH_COEFF and multiplying the
    returned state by CELT_EMPH_COEFF for the assembly function.

    Since its actually faster to do this in C as well, copy the behavior the
    asm versions use. As a reminder, the initial state 0 is divided by
    CELT_EMPH_COEFF on seek and init (just in case in the future this is
    changed, its technically more correct to init with CELT_EMPH_COEFF than 0,
    however when seeking this will result in more audiable pops, unlike with 0
    where the output gets in sync over a few samples).

  • FFmpeg more than 1000 frames duplicated and input height doesn't match

    2 septembre 2021, par Karine

    I'm currently using this code to record two windows side by side :

    


    ffmpeg -f gdigrab -framerate 30 -i title="" -f gdigrab -framerate 30 -i title="" -c:v h264_nvenc -qp 0 -filter_complex hstack=inputs=2 2.mp4


    


    However it throw this error after execution :

    


    More than 1000 frames duplicated


    


    Error Log : https://pastebin.com/gREVrKVK

    


    The first window mostly time is the same frame, maybe 1 frame change in each 3 sec.

    


    Another error in console is when the first window have a different height than second window, error :

    


    [Parsed_hstack_0 @ 000002491166fd00] Input 1 height 500 does not match input 0 height 488.
[Parsed_hstack_0 @ 000002491166fd00] Failed to configure output pad on Parsed_hstack_0


    


    Error log : https://pastebin.com/vqdBPfpv

    


    Looks like is not possible to record when they have different dimensions, so, if possible I would like to ask how to scale the first window to the same height (doesn't need to keep aspect ratio) of the second window, considering low CPU use above the video quality.
