php - ffmpeg mp4 file is not valid -


i looking answer on internet but, didn't find any...

got 3 movies, made ffmpeg separate frames in png files command:

ffmpeg -r 100 -qscale 2 -i input/%06d.png output/movie.mp4

two of them work perfectly... windows media player , others see correct format..., 1 of them not. vlc can play it, other players unknown format. has size of images. know criteria... size should have... why 1 working , other not...

sizes are:

  1. 1600x1570 - works fine
  2. 1880x616 - works fine
  3. 1891x725 - doesn't work...

this weird, because fullhd has width of 1920, above lower...

all images made php gdlib, saved same method... not problem of count, because no matter if first 100 frames, or whole movie, still doesn't work... last one. ideas possibly wrong?

complete ffmpeg output (for 200 frames):
