Hi Paddy Landau long time no see. I hope this is not to confusing.
I too a long time ago had to do something along these commands:
Code:
cat $(ls -t *jpg) | ffmpeg -f image2pipe -vcodec mjpeg -r 25 -i - -i backwards.wav -vcodec libx264 -vpre slow -crf 20 -threads 0 -acodec flac output.mkv
Or something like this also "should" work.
For video only>> this is from my notes back in the year 2016:
Code:
ffmpeg -i /storage/emulated/0/ffvid/frameCount.mp4 -vf reverse reversed.mp4
For audio and video:
Code:
ffmpeg -i /storage/emulated/0/ffvid/frameCount.mp4 -vf reverse -af areverse reversed.mp4
This filter buffers the entire clip. For larger files, segment the file, reverse each segment and then concat the reversed segments.
I got this idea form stackexchange and I think things have changed some since then.
Good Luck
