问题 I am trying to add text to video using ffmpeg and wants text to appear for a given period of time. I am trying to use DrawText filter but don't know how to provide time period for this filter. Can Anybody please help me. Thanks 回答1: The drawtext video filter has timeline editing support (see the output of ffmpeg -filters ). This can evaluate an expression and allows you to provide the time(s) of when the filter should be enabled. This example will enable the filter from 12 seconds to 3
