Recordings meta data

[NBOSTI]

I know it has been discussed before, but I can"t find the thread. Was some where in the earlier posts about cloning the drive without losing recordings?
I have copied the mkv files from Icebox to another drive on occassion in order to use on another player or edit the recording.
Player/editing software of choice will playback without issue but all program information/meta data is missing.
Where is that metadata located on the recorded file IceBox?

There is a section within our Help - IceBox Knowledge base under "Advanced Topics" titled Cloning an IceBox Drive?

It is my understanding that the .backup subfolder in the Recordings directory contains copies of the metadata for both timers and recordings. I cannot remember where the primary versions are stored (separate locations for timers and recordings), but I am sure that @Delta Mike Charlie will provide the location.

My recollection is that the ".backup" folder is not a standard LibreELEC/TVHeadend feature but was added by @Daniel Hall to aid in the recover of recordings when doing a soft reset.

PS the period at the commencement of the name of the .backup folder indicates that the folder is a hidden folder.

I used VLC to check an MKV recorded on my IceBox and I found that some of the metadata was already embedded in the recording file.



Here is some background for those who are interested:

Recording metadata storage is not immediately intuitive.

When a recording is first scheduled, it is allocated a unique identifier known as a UUID.  A UUID is a 32 character alphanumeric code.

The recording object is stored in JSON format using its UUID as the file name in the following location:

/storage/.kodi/userdata/addon_data/service.tvheadendicetv/dvr/log

For example, a file listing may look like this:

To find the UUID of a recording using the file name, you can try this command:

Code Select Expand

grep -i -r "Letters And Numbers-FTA-SBS ONE2024-03-2606-30.mkv" .|awk -F ":" '{print $1}'
This information is not easily accessible but can also be obtained from the TVH API.

The programme sub-title and recording comments have been recently added to TVH.  Also the parental rating was changed to show the rating text 'PG (AUS)' instead of the age.
