Add image overlay on video FFmpeg

Question

I have a video, test.mp4, and an image, test.png.

test.png is a black image with a transparent \"hole\" in the center.

Answer 1

I used this on android and its working fine :-

String[] cmd = new String[]{ "-i", video.mp4, "-i", image.png, "-filter_complex", "overlay=0:main_h-overlay_h", outputFile.getPath()};

Answer 2

Try this:

ffmpeg -i test.mp4 -framerate 30000/1001 -loop 1 -i test.png -filter_complex "[1:v] fade=out:st=30:d=1:alpha=1 [ov]; [0:v][ov] overlay=10:10 [v]" -map "[v]" -map 0:a -c:v libx264 -c:a copy -shortest out.mp4
