  • ffmpeg image to video sequence stops after 10

    18 mai 2012, par Jim

    Probably a fast anwser, but my first time trying to do this. I have 77 jpeg pictures, I have renamed them to be 000.jpg - 076.jpg. The next step is using ffmpeg and here is my command statement :

    ffmpeg -f image2 -r .1 -i %d.jpg -r 25 test.avi

    It creates an avi with 10 images for 10seconds each, why only 10 ? I've tried other iterations of %d.jpg in the ffmpeg command with no success.

    thanks for the help all !

    -Jim

    Here is the listing of the directory with the images :

    ls -l

  • FFMPEG produce sharper image from audio to video

    19 mai 2012, par Pjack

    I am using ffmpeg to create video file from by using the loop_input command and create an flv file as a wrapper then export it as mp4. For some reason when the video plays the image is clear as time goes on it starts to get really pixelated. Is there something I need to do to retain the quality during the looping or anywhere else that would help ?

    This is my video out parameters, not the whole line.

    ffmpeg -loop_input -f image2 -i myimage.jpg -r 20 -g 20 -vcodec flv
