  • Android - merge videos taken with front and back cameras

    3 mai 2023, par Raz Leshem

    I am having an orientation problem when merging videos taken with front and back cameras in portrait, recorded using Android CameraX.

    


    This issue is explained here, but I am yet to find a working solution. I have tried multiple solutions, such as using mp4parser as suggested in the issue explanation, but the result is a that every alternate camera video is upside down.
I also tried using FFmpeg for android - mobile-ffmpeg.
Using ffmpeg Concat demuxer resulted in the same result as mp4parser did.

    


    Concat demuxer command I used : ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4

    


    I also tried changing the rotation metadata of the videos to match before concatenating, similar to how it's done here, but that did not seem to have any effect on the end result.

    


    Lastly, I used ffmpeg Concat filter. That solution took longer obviously because of the re-encoding of the video but it did fix the problem of the orientation of the videos, but the output video quality was poor.

    


    Concat filter command :

    


    ffmpeg -i front1.mp4 -i rear1.mp4 -i front2.mp4 \
-filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] \
concat=n=3:v=1:a=1 [v] [a]" \
-map "[v]" -map "[a]" output.mp4


    


    Has anyone found a solution on how to fix the orientation problem in android ? or maybe how can I keep the videos quality as much as possible when using the FFmpeg Concat filter to merge the videos ?

    


  • avformat/matroskaenc : Add option to shift data to write cues at front

    9 janvier 2022, par Andreas Rheinhardt
    avformat/matroskaenc : Add option to shift data to write cues at front

    This is similar to the faststart option of the mov muxer, yet
    
in contrast to it it works together with reserve_index_space
    
(the equivalent to reserved_moov_size) : If the reserved space
    
does not suffice, the data is shifted ; if not, the Cues are
    
written at the front without shifting the data.
    
Several tests that cover (not only) this have been added.
    

    Implements #7017.
