  • FFmpeg add caption to top of video like memes

    25 juin 2018, par Praveen Tamil

    I’m trying to add a top section to a video like we do for image memes. I’m using drawtext option for that but the text is wrapped in output video.

    Let’s say I have a video and I need to add the caption like this to the whole video. How can i achieve this ?
