ffmpeg -i out.mp4 -i scaledSquare.png -filter_complex " [0:v][1] overlay=100:100:enable=’gte(t,0)’" -y test3.mp4
which supposed to add the shape from all times greater than 0, which works fine , shape is getting added for the whole duration of output.
So I am not sure why the enable option does not work when I specify something like enable=’gte(t,3)’ or enable=’between(t,1,3)’ here.
and just for additional information :
I created the original mp4 file (out.mp4) by adding an mp3 file to one png image as belowffmpeg -i images/08.png -i audio_123e4567-e89b-12d3-a456-426655440000.mp3 -pix_fmt yuv420p out.mp4

Failed encoding Carrierwave-video FFMPEG
12 septembre 2018, par Cole PhiperI’m using Carrierwave-video and Carrierwave-ffmpegthumbnailer. The problem I am having, is the transcoder is now refusing to work & I can’t locate the origin of the error. I tried removing some of the custom settings, but nothing seems to work. How can I fix the transcoder to allow video uploads ?
