    15 octobre 2018, par Julien

    As you can see there are some errors, there. I’ve tried with several different mp4 files, from different sources so it’s not a problem of the video files.

    I’ve also tried without the -movflags faststart option, also tried with -q:v 0 instead of -crf 0, nothing works, but like stated above, it works from FLV -> MP4, what am i doing wrong here ?

    PS : By "Nothing works" I mean the resulting MP4 plays for 1 frame in the browser and stops.

  • ffmpeg concat + scale2ref, reduced framerate

    15 décembre 2020, par Erwan Douaille

    I would like to concatenate multiple videos with differents aspect ratio, framerates, etc.
The working solution is scale2ref option with black background, no re-scale and concat.

    


    If I use my command line with movie1.mp4 (30fps 1920x1080 2sec) and movie2.mp4 (25fps 800x600 3sec) I except a final output at 25fps 1920x1080 5sec. This part works well.

    


    Then if I use my command line with movie1.mp4 (30fps 1920x1080 2sec) and movie2.mp4 (30fps 1920x1080 3sec) I except a final output at 30fps 1920x1080 5sec. But for an unknown reason my final output is 25fps 1920x1080 5 sec.

    


    I tried with a copy of movie1.mp4 and rename it to movie2.mp4 to ensure they are both perfectly identical and got the same issue.

    Here is my command line :

    


    ffmpeg -y -f lavfi -i color -i ./1.mp4 -i ./2.mp4 -filter_complex_script ./3.txt  ./out.mp4


    


    The content of filter comple script :

    


    [0][1]scale2ref[canvas][vid1];[canvas][2]scale2ref='max(iw,main_w)':'max(ih,main_h)'[canvas][vid2];[canvas]split=2[canvas1][canvas2];[canvas1][vid1]overlay=x='(W-w)/2':y='(H-h)/2':shortest=1[vid1];[canvas2][vid2]overlay=x='(W-w)/2':y='(H-h)/2':shortest=1[vid2];[vid1][vid2]concat=n=2:v=1,setsar=1


    


    I´m quite sure it´s related to the lavfi input but I don´t know how to enforce it to be the best framerate available.

    


    Is it possible to enforce the "best" framerate available ?
Something like :

    


      

    • 30fps + 30fps = 30fps

      • 


    • 25fps + 25fps = 25fps

      • 


    • 25fps + 30fps = 30fps (or maybe 25 with perfect down sampling for the 30fps video)

      • 


    


    My ffmpeg commands are programmaticaly generated. Any automatic solution is prefered.
