Ffmpeg generated movie (png -> mp4) has no video
21 avril 2016, par ILiveForVRI have a whole bunch of png’s which I would like to convert into a mp4 video.
I am using the following command to stich them together :
ffmpeg -i _2016-04-20_14-51-00-500_%06d.png -pix_fmt yuv420p movie.mp4
I am getting a file, which has a size so it isn’t empty. But when I play it in VLC or Quicktime it shows the time going by, but it has no video in it. Any idea what I’m doing wrong ?
I also tried :ffmpeg -framerate 1/5 -i _2016-04-20_14-51-00-500_%06d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4
and
ffmpeg -r 45 -f image2 -s 1920x1080 -i _2016-04-20_14-51-00-500_%06d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p test.mp4
But still no video.
This is the commandline output :>ffmpeg -i _2016-04-20_14-51-00-500_%06d.png -pix_fmt yuv420p movie.mp4
