FFmpeg generated video length doesn't match expected length [on hold]
21 juin 2018, par BentCoderI am using command below to generate video out of images. The problem is the length out the video generated. It is always 5 seconds less than expected. If I have 4 images, I expect to see 20 seconds of video but I am getting 15 seconds instead. The very last image
img-03.jpg
just appears at the end of the video as if it is a cover image. Any idea why and solution ?Command
ffmpeg -y -framerate 1/5 -f image2 \
