    imgutils : add function to clear an image to black

    Black isn't always just memset(ptr, 0, size). Limited YUV in particular
    
requires relatively non-obvious values, and filling a frame with
    
repeating 0 bytes is disallowed in some contexts. With component sizes
    
larger than 8 or packed YUV, this can become relatively complicated. So
    
having a generic function for this seems helpful.
    

    In order to handle the complex cases in a generic way without destroying
    
performance, this code attempts to compute a black pixel, and then uses
    
that value to clear the image data quickly by using a function like
    
memset.
    

    Common cases like yuv410p10 or rgba can't be handled with a simple
    
memset, so there is some code to fill memory with 2/4/8 byte patterns.
    
For the remaining cases, a generic slow fallback is used.

  • FFMpeg Drawtext black pixels behind the font

    21 janvier 2023, par sweetngx

    I burn the name of the movie with drawtext to my movies converted with FFMPeg, but I noticed that the black pixels around the font are disturbing, as seen in the picture. I don't know if this is a missing line of code or the nature of drawtext itself. Do you think there is a solution to make the movie name more legible ?
