I need to create a video from data (images) per day basis. Task Descriptionĭirectory contains thousand of images each after few minutes of a construction project. but running it via gui subprocess, errors out. What's irritating me is, if I copied second line from log (dos cmd) and paste it in a cmd prompt, it works successfully and produces video correctly. from log, first two lines shows command list and command string.
