  • 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 outputPath

  • 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.

  • (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.
