  • timelapse images into a movie, 500 at a time

    2 mars 2017, par molly78

    I am trying to make a script to turn a bunch of timelapse images into a movie, using ffmpeg.

    The latest problem is how to loop thru the images in, say, batches of 500.

    There could be 100 images from the day, or there could be 5000 images.

    The reason for breaking this apart is due to running out of memory.

    Afterwards I would need to cat them using MP4Box to join all together...

    I am entirely new to bash, but not entirely programming.

    What I think needs to happen is this

    1) read in the folders contents as the images may not be consecutively named

    2) send ffmpeg a list of 500 at a time to process (https://trac.ffmpeg.org/wiki/Concatenate)

    2b) while you’re looping thru this, set a counter to determine how many loops you’ve done

    3) use the number of loops to create the MP4Box cat command line to join them all at the end.

    the basic script that works if there’s only say 500 images is :

    #!/bin/bash
    

    
dy=$(date '+%Y-%m-%d')
    

    
ffmpeg -framerate 24 -s hd1080 -pattern_type glob -i "/mnt/cams/Camera1/$dy/*.jpg" -vcodec libx264 -pix_fmt yuv420p Cam1-"$dy".mp4

    MP4Box’s cat command looks like :

    MP4Box -cat Cam1-$dy7.mp4 -cat Cam1-$dy6.mp4 -cat Cam1-$dy5.mp4 -cat Cam1-$dy4.mp4 -cat Cam1-$dy3.mp4 -cat Cam1-$dy2.mp4 -cat Cam1-$dy1.mp4 "Cam1 - $dy1 to $dy7.mp4"

    Needless to say help is immensely appreciated for my project
