Hi, I am using Libavfilter programmatically and I know its possible to overlay an image like a logo onto a video with a filterchain. Is it possible to change the image that I am overlaying part way through the video? The idea being that the overlaid image will change every *n* number of frames. Is this possible with a filtergraph?
The only other way I can think of is to make a separate video where each frame contains my overlay image with a transparent background. Then overlay one on top of the other. Does this sound viable? Cheers,
