But the following error occurred.

Encoding a readable movie by QuickTime using FFMPEG
3 octobre 2014, par itamarbI’m trying to encode an image sequence using the following command :
ffmpeg.exe -i %d.png -f mp4 -vcodec h264 test.mp4
However, QuickTime failed to open this file or sometimes play a black movie, while this movie plays great in VLC player. Any suggestions how to make it play well in QuickTime ?
Here is the output :
ffmpeg.exe -i %d.png -f mp4 -vcodec libx264 13.mp4
