How can I create a mpg/mp4 file from let's say 10 images using ffmpeg.
Each image shall stay for 5 minutes, after the 5 minutes are over the next image shall appear and so on....
How can I achieve this?
回答1:
If your images are numbered in a sequence (img001, img002, img003..), use
ffmpeg -framerate 1/300 -i img%3d.jpg -r 5 video.mp4
(I've set an output framerate of 5 for player compatibility. Each image will still remain for 300 seconds)
If your filenames are irregular, and you are executing in a Unix shell like bash, you can run
ffmpeg -framerate 1/300 -pattern_type glob -i '*.jpg' -r 5 video.mp4
For MPEG-2,
ffmpeg -framerate 1/300 -i img%3d.jpg -c:v mpeg2video -b:v 2000k -r 5 video.mpg
No idea what minimum output framerates are expected of MPEG-2. Experiment.
