FFMPEG add image at the end of a video

问题

I need to add an image for one second at the end of a .mp4 video file using FFMPEG. My video size is WxH and my image size is MxM, so video and image sizes are different.

I have tried different options in order to add the image at the end of the video as:

ffmpeg -i "concat: videoIn.mp4|image.jpg" -c copy videoOut.mp4

or

ffmpeg -i videoIn.mp4 -loop 1 -t 1 -i image.jpg -f lavfi -t 2 -i anullsrc -filter_complex "[0:v][0:a][1:v][2:a] concat = n=2:v=1:a=1[v][a] -c:v libx264 -c:a aac -strict -2 -map" [v] "-map" [a]" videoOut.mp4

but none gave me the result I need.

Can someone help me?

Kind regards

Use

ffmpeg -i videoIn.mp4 -loop 1 -t 1 -i image.jpg -f lavfi -t 1 -i anullsrc -filter_complex "[1:v]scale=WxH:force_original_aspect_ratio=decrease,pad=W:H:'(ow-iw)/2':'(oh-ih)/2'[i];[0:v][0:a][i][2:a] concat=n=2:v=1:a=1[v][a]" -c:v libx264 -c:a aac -map "[v]" -map "[a]" videoOut.mp4

The image is resized to fit within a WxH frame size and then padded to get the video's frame size.

You'll need ffmpeg 3.4.2 or later.
