[FFmpeg-user] corrupted mp4 encoded from images sent from a pipe

Tue Dec 10 16:22:01 CET 2013

I've generated images with phantomjs instead of sending to the pipe.
I have img001.png, img002.png...
I'm calling the command:
../ffmpeg -r 1 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p
out.mp4

The video is still corrupted.

../ffmpeg -r 1 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p
out.mp4
