Hi, in my application I want to generate few effects with ffmpeg. This is modified overlay filter that allows to create moving effect.
example: ffmpeg -i <background_video> -vfilters "[in]setpts=PTS-STARTPTS,[T1]overlay=<formula>[out];movie=0:avi:<video_file>,scale=<scale_resolution>,setpts=PTS-STARTPTS[T1]" -vcodec mjpeg -b 200k -r 25 -qscale .1 -y <target> forumula example: -20+14*atan(N/30):20-14*atan(N/30) ------- -<delta>+<delta_pi_x>*atan(N/<speed>):<delta>-<delta_pi>*atan(N/<speed>)
vf_overlay.patch
Description: Binary data
