I am trying to create a simple slideshow video based on two images ('ocean001.jpg' and 'ocean002.jpg'). I am using the command as listed in the ffmpeg documentation, but i always end up with a blank (e.g. black) video file 15 seconds in duration.
I have checked to confirm that the two image files are the same size. Both are 1024x768px.There are also no errors reported.
Can anyone tell me what I am doing wrong?
Here is the output of the command I am using:
ffmpeg -f image2 -r 1/15 -i ocean%03d.jpg -vcodec libx264 out.mp4 Below is the output of the above command:
