I'm successfully creating animations from a series of static png's. I also want to add a watermark, but I'm having some issues when trying to add the watermark source.
Using this generates the animations fine:
ffmpeg -v warning -framerate 4 -i /tmp/img-%d.png -i /tmp/img-palette.png -lavfi "paletteuse" -y -loop 0 -vcodec libx264 -crf 25 -pix_fmt yuv420p -hide_banner /tmp/output.mp4
When I add the following to specify the watermark source (transparent png) an error is generated:
-i /tmp/logo.png -filter_complex "overlay=x=(main_w-100):(main_h-50)"
Full command:
ffmpeg -v warning -framerate 4 -i /tmp/logo.png -filter_complex "overlay=x=(main_w-100):(main_h-50)" -i /tmp/img-%d.png -i /tmp/img-palette.png -lavfi "paletteuse" -y -loop 0 -vcodec libx264 -crf 25 -pix_fmt yuv420p -hide_banner /tmp/output.mp4
Error:
video:1kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown
Do I need to generate the animation first, then apply the watermark to that artifact or is there a way to combine everything together during the creation process?
