daily digest script suggestions?

[vajonam]

I have script that used to run on a nightly basis, that fins all the .mp4 and combines at faster frame rate so can see the days events that i missed.

ls -lR /net/security/frigate/recordings/2023-04-14/*/front/*.mp4

this shows me something I didn't expect.

... more stuff that i epxpect 

Basically the created time of the files spread into the previous day are the current days folder? is this because of timezones? is there a better way to get the days events clips and send them over to ffmpeg?

I am in the America/Toronto timezone, so GMT+5

[NickM-27]

As of 0.12, the recordings are stored in a folder structure based on UTC, which prevents issues with things like daylight savings time, moving across timezones, etc. This was listed in the release notes breaking changes and had a dedicated section as well.

[vajonam]

thanks @NickM-27 , I just joined the community after 0.12 release, so didn't regard the breaking changes! nothing to break for me. the script was from a previous NVR software that stored it by local TZ.

[vajonam]

Just for completeness

find $STORAGE_PATH/*/*/${MONITOR} -newermt 20230416 ! -newermt 20230417  -name "*.mp4" -type f   -printf "%T+ %p\n" | sort -V | awk '{print $2}' 

will get you a list of events sorted correctly by created mtime on the local file system in the local timezone, if anyone is interested. not sure you need the -V in sort but left it in there from previous script

[blakeblackshear]

This is an example of how you can just use the api to let frigate put together a playlist for you: #2369 (comment)

You just have to pass a single input to ffmpeg.

Thanks was going to dig into using the API today, just perfect timing. I was just trying to use previous script I had, seemed there would be a better way and there is! Awesome!
