• create video with fluctuated background color and drawbox with fluctuated color ?

  27 mai 2019, par Wang

  Is there anyway to create a video with fluctuated background color choosing from a list for example [R, G, B] the background color along time will be R,G,B,R,G,B .... I might use nullsrc with geq. But seems the geq is quite slow which apply to each pixel.

  I would also like to change the color of drawbox too, is there any easy way to do it ? I knew we might be able to use openclsrc but it seems overkill for this simple task.

  Update, for drawbox I found a way, which is kind of abuse the timeline editing :

  ffmpeg -f lavfi -i smptebars=r=30:d=30:size=800x600 -vf "drawbox=enable='eq(mod(n,3),0)':x=0:y=0:t=20:c=red,drawbox=enable='eq(mod(n,3),1)':x=0:y=0:t=20:c=green,drawbox=enable='eq(mod(n,3),2)':x=0:y=0:t=20:c=blue" /tmp/test_box.mp4

  Fixing display size setting problem.

  Fix of https://code.google.com/p/webm/issues/detail?id=608. We could have
  used invalid display size equal to the previous frame size (not to the
  current frame size).
