[Issue]: Live TV Recordings No Longer Scheduled

[michaelcresswell]

Please describe your bug

Live TV episodes are no longer scheduled for recording. Scheduling a recording for either a single episode or a series results in a loading spinner, an error in the server log, and no recording being created.

This has been seen on an instance migrated from 10.8.13 and a fresh 10.9.0 instance with only the HDHomeRun and XMLTV guide data file setup.

I tried giving the directory mentioned in the error log and its underlying files 777 as well as not mounting a directory so the files would be used directly from the jellyfin image.

This worked in 10.8.13.

Reproduction Steps

With an HDHomeRun setup and XMLTV data imported,

1. Navigate to the Live TV Guide
2. Choose an episode and select Record

Jellyfin Version

10.9.0
10.9.1

if other:

All options that could prevent recording are as permissive as possible.

One episode claims to be recording and another scheduled. Neither were actually recorded.

I get the same error. No FFMPEG log, also. LiveTV was working prior to upgrade to 10.9.0.

I swapped logs from informational to debug and clicked record and this is the output:

Not only is there no recording, I can't even play live TV any longer.

I can play just can't record.

I see instances of this in my log as well but the scheduled task succeeded when I re-ran it manually, this time at least

[michaelcresswell]

Not only is there no recording, I can't even play live TV any longer.

I can play just can't record.

Seems client-dependent to me, Web doesn't play Live TV but iOS Expo does.

Playback problems are likely a separate issue though.

[jurgenhaas]

Playback problems are likely a separate issue though.

The browser console showed many javascript errors, most of which because they received 500 errors from the server. But that was yesterday, looks like the update to 10.9.1 fixed those.

[ch6574]

I experience the same on 10.9.1 under Debian 12, plus I have also noticed that refreshing the TV guide data throws the below errors:

I confirmed the permissions were the same on the folder as were before the 10.9.* upgrades.

I renamed the jellyfin/data/livetv folder to livetv_old, hoping it would recreate it.

I chose a random show, Father Knows Best, and tried to live record it. It started recording.
Instead of a jellyfin/data/livetv folder with Json files in it, it created a single text file with no extension called 'livetv'  with this in it:

    }
]

I then ran the guide update, which ran successfully. It had been failing. See my above reply.

I looked at the livetv file, and it remained the same. Nothing from my guide that should have been scheduled, was scheduled. and all of my previous series and schedules are gone when I looked on the web.

EDIT to add:
I tried to setup a new series recording, and got this in my log:

[2024-05-13 10:08:04.980 -04:00] [ERR] [15] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request: "Cannot create 'C:\Users\USERNAME\AppData\Local\Jellyfin\data\livetv' because a file or directory with the same name already exists". URL "POST" "/LiveTv/SeriesTimers".

I hope this makes sense to anyone.

[ch6574]

Speculating here, but it seems the filename is being lost on the path, and Jellyfin is trying to perform file operations on a directory (hence the "System.UnauthorizedAccessException" errors).
