  • How to add text watermark to output video when using ffmpeg ? [duplicate]

    29 janvier 2018, par Jithin Shaji

    This question already has an answer here :

    Iam developing an android app for video editing using ffmpeg plugin. I need to add a watermark text(not image) to all the output videos after encoding. How can I achieve that ? For example Iam splitting a video into segments using the command

    ffmpeg -i inputfile -acodec copy -f segment -segment_time 30 -vcodec copy -reset_timestamps 1 -map 0 outfile

    How can I add watermarktext to the outfile ? I found one solution at ffmpeg text watermark bottom left.
    But I need to combine both commands (Split command and drawtext command)

  • Add text to a video with effects using FFMPEG

    9 mars 2014, par user2727765

    I need to add text in between a video. I have seen drawtext and seems it wont give effects to the text to be displayed.

    My intention is to show a text within a box with some background to that box which should fly from left to right in between a video at a particular time. Is it possible with FFMPEG ? I have tried different options with drawtext and nothing seems to be working. Any ideas on how to make it ?

    or is it possible to achieve by combining imagemagick and FFMPEG command ?

  • ffmpeg only drawing last text

    24 juillet 2020, par Muhammad Mohsin Ajmal

    Im 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 ?
