• FFMPEG detect position of text and hide/delogo

  9 novembre 2016, par Ates Özen

  I’ve tried a lot of ways to do that. Is it possible to detect the position of a text in a video and hide/watermark it with delogo in ffmpeg ?

  You can see something like what i want in this video at 30th second :

  In my situation the text is not rectangled.

• Merge videos with different start times and show them on a grid

  1er août 2017, par shamaleyte

  I have multiple video files of a conference call. However, each participant joined the call at a different time, which resulted in the fact that each video file has a different start time offset values.

  Video   Start Time
  
  ------------------
  
  Video1  00:00
  
  Video2  00:10
  
  Video3  01:40

  My purpose is to play back this conference. However, I did not record the conference as 1 video, it is recorded with multiple video files, instead.
  How do I stitch these videos ?

  There is also a paid solution to merge video fragments to a single clip – this will make the client-side much simpler. But can I do it for free ?

  The expected outcome is to have one video showing three videos on a grid.
  When ffmpeg stitches the videos, it should consider their start time values properly so that the videos are played accordingly.
