  • ffmpeg slideshow not working

    4 février 2013, par Benjen

    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 :

    I want to convert png images into mp4, this my ffmpeg code :

    /usr/local/vencode/bin/ffmpeg -y -framerate 1/5 -i      /home/fanzaholic/public_html/lab/server/script/1411400997_open_%03d.png -c:v libx264 -r 30 -pix_fmt yuv420p /home/fanzaholic/public_html/lab/server/script/test.mp4 2>&1
