Summary of the bug:
Setting `setpts=N/60/TB` (> 25) followed by `fps=60` for a single image
input, ffmpeg somehow hangs producing empty 0 bytes output.
How to reproduce:
{{{
ffmpeg -f lavfi -i color=size=500x300:rate=60 -filter_complex
movie=image.png,setpts=N/60/TB,fps=60,tpad=stop_mode=clone:stop_duration=5[v];[0][v]overlay=eof_action=pass[v]
-map [v] -t 10 -y 60.mp4
}}}
...changing setpts to value like `N/25/TB` works ok.
tested with latest version of ffmpeg 631e31773b from
