Comskip in Linux container is crashing in 2025.08.19.2102

Beta Community DVR Beta
#1

I'm seeing a rare crash when detecting commercials for American Ninja Warrior recorded from a broadcast channel using an HD Homerun & antenna. The only thing in the logs is:

2025/08/19 20:54:09.805545 [DVR] Running commercial detection on file 14063 (TV/American Ninja Warrior/American Ninja Warrior S17E12 Finals 3 2025-08-18-1959.mpg)

Donator build
Received signal 11 (Segmentation fault)

It doesn't seem to produce any comskip logs when it fails like this.

Running commercial detection on other shows from various sources works fine, it only seems to crash on this show. The show plays just fine in Channels on my Apple TV. I've submitted diagnostics under 0dd1a2f5-3e41-4d1a-9993-04a38d41c660. You mentioned changes to comskip in a beta from yesterday, so I'm reporting the failure. I'm running Channels DVR on my Synology DS1821+ in a container.

[TVOS/IOS] v2025.08.18.1309 • IMPROVED: more commercial skipping changes. Please report any changed behavior to Community.

I think this is happening to me too on Synology. These were also recordings from my HDHomerun and are both MPEG2/1080i.

Comskip seems to be working as expected on this HDHomerun MPEG2/720p channel though

I'm having the same problem with my Synology NAS too.

Getting a slightly different error:

2025/08/20 09:00:00.705157 [DVR] Commercial detection failed for Today S73E283 2025-08-20-0700.mpg: exit status 11: Comskip 0.82.011, made using ffmpeg

IIRC from previous investigations, failing with an error of 11 relates to the process running out of memory.

This is unrelated. That relates to the client devices, while your issue is with the DVR server itself.

#8

Has anyone had any luck with their Linux/Synology comskip? Like I mentioned earlier my 720p/MPEG2 recordings are successful but it's immediately failing with the 1080i/MPEG2 recordings, something it never had a problem with for years.

#9

Oops, good point. The latest beta seems to be proceeding on the same show.

#10

Looks like latest prerelease solved it for me. Thanks devs!
