    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.

    28 juillet 2022, par Saran Raj

    xvfb-run —listen-tcp —server-num 44 -s "-ac -screen 0 1920x1080x24" mvn clean test &
    &#xA;export DISPLAY=:44
    &#xA;ffmpeg -f x11grab -video_size 1920x1080 -i :44 -codec:v libx264 -r 12 video.mp4

    &#xA;

    This is the bash script i am using to run the selenium test cases(in headless mode) with maven as the build tool in port 44 and capture it.&#xA;But when i execute it i only get a black screen. What to do ?
