Comment (by Michael Koch):
When I saw this issue, I first thought it's because the inputs might be
yuv420 and the size is incremented in steps of one. So I added a few
"format=rgb24" and "format=auto".
ffmpeg -filter_complex
"color=color=#000000:rate=20:size=400x400,format=rgb24[b];color=color=#ffffff:rate=20:size=100x100,scale=width=iw+n:height=ih+n:eval=frame,format=rgb24[w];color=color=#ff0000:rate=20,format=rgb24[r];[r][w]scale2ref=eval=frame[r][w];[w][r]overlay=format=auto[w];[b][w]overlay=format=auto"
-t 4 -y gif.mp4
But now ffmpeg never stops. Is there an explanation for this behaviour?
Michael
