[FR] Timelapse from the recorded footage

It would be really nice to have a feature on the web page to generate and store a speeded-up timelapse from the selected camera at the set timeframes and speed.

Now, I just copy the relevant files, concatenate them and generate time-lapse with this command:

for f in `ls -tUr  recordings/2021-01/25/**/camera_name/*.mp4`; do echo "file '$f'" >> tempfilelist.txt; done
ffmpeg -f concat -i tempfilelist.txt -c copy concatenated.mp4
ffmpeg -i concatenated.mp4 -filter:v "setpts=0.1*PTS" output.mp4

The way folders are structured/files are named, it can be a bit inconvenient to generate timelapse e.g. from 11.30 to 12.45.

Let me know if you’d be willing to merge this if I made a PR.

This is still something I am considering.

Maybe an option to record in timelapse.
