22 mars 2021, par Toni Cambronero GarciaHow can I indent code in a Batch script other than using temporal variables %= =% ?
This is the only code that works for me with indentation.

ffmpeg only drawing last text
24 juillet 2020, par Muhammad Mohsin AjmalIm using ffmpeg in flutter using the flutter ffmpeg plugin. While experimenting with it this is what I am trying to do : Show text between 1 to 2 seconds and a different text between 3 to 4 seconds in video.


Only the text mentioned between 3 to 4 seconds is shown. So for me only the last drawText would work. What am I missing here ?
