  • (no accepted answer) How to merge 2 overlapping videos into one video using ffmpeg or opencv ?

    3 janvier 2021, par Muhammad Umer

    Merging two videos is easy, been answered couple of times. What I have is multiple overlapping videos. A video might have overlaps with video before it. Meaning if video 1 covers 1-5 timeline then video 2 may overlap 1, and cover 3 to 8. Merging them as is would result in 1-5|3-8, when i need 1-8 only.

    &#xA;&#xA;

    Videos are alphabetically sorted.

    &#xA;&#xA;

    My general idea of solution is...

    &#xA;&#xA;

      &#xA;
    • grab last frame of the video

      • &#xA;

    • if it's first video continue

      • &#xA;

    • if it's not first video, ie. 2nd, search for frame saved in previous steps frame by frame

      • &#xA;

    • if it reaches to last frame of current video then there is no overlap continue

      • &#xA;

    • if it founds a frame then clip 2nd video up to that frame inclusive and then go to next frame

      • &#xA;

    • once all videos have been analyzed, merge them into one video.

      • &#xA;

    &#xA;&#xA;

    I need to translate this to ffmpeg commands. Or opencv if that's a better tool.

    &#xA;&#xA;

    If there is better way of doing that, I'm interested in that too.

    &#xA;
