I'm making an AVFilterGraph in code. I need to apply a watermark to the video.
My assumption is that I need to use the "movie" AVFilter to then overlay it. My watermark is just stored in memory, not in a file, so I'm unsure how to point the "movie" filter to use that watermark?
Can someone clarify how I would do that?
My current filter graph is basically:
buffer -> (optional rotation) -> scale -> pad -> buffersink
The watermark would come in after the pad and overlaid there.
