All scheduled recordings are truncated. Some end up less than a minute.

[astuff 3]

I am using a Mac M4 with MacOS 27.0.1 with HDHomerun and EmbyServer 4.10.2.0.  It has been happening for several weeks and the update did not fix the issue.  Watching truly live I haven't seen an issue.

Latest example:  I had a 30 minute recording scheduled for last night but it ended up creating a 10 minutes and 57 second recording.

Any ideas of what to try?  The logs don't show anything happening outside of the scheduled start and end times.

Hi, is this the log from when the recording happened?

[astuff 3]

Yes.  The recording started just before 8:30PM (20:29 in the file).

Hi, the server is acting like the recording stopped after 32 minutes:

2026-10-23 21:02:59.996 Info LiveTV: Recording stopped: 18fe9e684ac6b516b9455663ee97461f /Users/saulinpa/emby-server/data/livetv/recordings/Newlyweds (2026)/Season 1/Newlyweds S01E01 Pilot.ts

What makes you think the recording was truncated? Also i notice the server log has no activity in between the recording starting and stopping 30 minutes later. Could the machine be going to sleep?

Two reasons to think that the recording was truncated:
 1 - Watching the recording only has the first 10 minutes of the program and then ends.  This is now happening on most recordings but varying times.
 2 - The size of the .ts file is smaller than normal. 

The system setting for “Prevent automatic sleeping when the display is off" is enabled.  As far as I can tell the machine isn't going to sleep and the system logs don't show going to sleep.  Actually showing EmbyServer messages.

OK but it's odd that the log is empty during that time. Perhaps the machine wasn't entirely going to sleep, but perhaps the OS put something to sleep that is preventing it.

As a  test, can you try another 30 minute recording, only this time, stay at your machine the entire time and every few minutes pull up the emby web interface. Thanks.

I scheduled two series on IPTV (Live TV) to record this week and although it records ever episode I get the same, every episode are approx 10 mins when the episodes are 40-45mins long.  It is usually the first 10-12mins of the episode and the TS files are only 120mb

If 10 minute cut off happens all the time, perhaps there is a Windows issue.

It may be sleep related as it doesn't seem to goof up when I am actively doing things.  But it also seems to work for a day or two after

I turned the display sleep off as well so the machine shouldn't be sleeping.

Here's last night's 2 minute recording.  At 20:30 the log shows the recording kicking off and stopping at 21:02.  Any concern that it is "refreshed" at 20:31 ?  The recording itself is exactly 2 minutes
