Hello,
We would like to run the image2 output format with the update flag, such that
it continuously updates a single image (very useful for website thumbnails…)
but we can’t for the death of us not find out how to specify it. Can anyone
help?
we have tried it like this:
ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 -f image2
-fflags +update frame.jpg -y
It's a private option of the image2 muxer, so
ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 -f image2
-update 1 frame.jpg -y
