[FFmpeg-user] overlaying animated PNG, doesn't loop

Mon Jan 11 10:08:03 EET 2021

Yeah, sorry.  Stuck on Windows at the moment and I was anticipating
difficulty updating, but it was fine.

Same behaviour in this version:

$ ./ffmpeg-N-100581-ga454a0c14f-win64-gpl/bin/ffmpeg -i ../input.mp4 -i ../elephant.apng -filter_complex "[0:v][1:v] overlay=25:25:enable='between(t,0,4)'" -pix_fmt yuv420p -c:a copy output.mp4
