• (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.

  



  Videos are alphabetically sorted.

  



  My general idea of solution is...

  



  

  • grab last frame of the video

  


  • if it's first video continue

  


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

  


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

  


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

  


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

  


  



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

  



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

  


• Requirements for using ffmpeg to create mpeg4 files in SaaS solution

  25 août 2016, par Paul Fleming

  My requirement is :
   On upload of a supported video file, convert the file to common formats to maximize web compatibility.

  Essentially, I want to take a non-web-supported video file, and converted it to WEBM and MPEG4. This will take place on a Windows Server VM inside Microsoft Azure.

  ffmpeg seems to be the de facto standard for video conversion yet it introduces licensing hell, not only with GPL/LGPL but by not offering a commercial license, meaning I now have to worry about paying royalties to MPEG-LA.

  Can anyone advise on MPEG-LAs licensing model as it applies to SaaS ? I will not be distributing ffmpeg (runs server side) and the conversion takes place on Windows (Server) OS.

• Comparison of two ffmpeg commands for video segment

  14 juillet 2021, par Anas Ansari

  I have two commands for making video segments in android ffmpeg

  


  

  • -ss startTime -i inputVideo -f segment -segment_time segmentDuration -reset_timestamps 1 -vcodec copy -b:v2 097152 -b:a 48000 -ac 2 -ar 22050 outputPath

  


  • -ss startTime -i inputVideo -f segment -segment_time segmentDuration -reset_timestamps 1 outputPath

  


  


  I have tried them both and noticed that first command is very very fast than second

  


  Since I am new to ffmpeg , i really don't know them meaning of every argument in these commands

  


  Can anyone plz explain me why first command is better and will it cause any errors in future
