Hi all,
I am trying to convert a set of images to a video file. I have tried
various ffmpeg command options but they all have failed. (command & error
logs attached: ffmpeg_errors.txt)
The following seems to work for me:
ffmpeg -f concat -safe 0 -i <(cat <<EOF
file '$(pwd)/image01.png'
duration 1
file '$(pwd)/image02.png'
duration 1
file '$(pwd)/image03.png'
duration 1
EOF
) output.avi
Is there something on which i am missing out?
Please help.
Thanks & Regards,
Puneet
