Creating a video from a single image for a specific duration in ffmpeg

问题

How do I generate a movie using ffmpeg using a single image (image1.png) for a duration of 15 seconds with a specific resolution so when I play the video, the image will appear on screen for 15 seconds.

回答1:

ffmpeg -loop 1 -i image.png -c:v libx264 -t 15 -pix_fmt yuv420p -vf scale=320:240 out.mp4

• The -t 15 makes it 15 seconds long.
• The -vf scale=320:240 sets the width/height.

Make sure to use an actual ffmpeg version e.g. http://johnvansickle.com/ffmpeg/
