Commercial Detection Fail

crisbell · February 9, 2017, 2:58am

Hi Guys…Starting last night none of my shows were able to mark the commercials for any of my recordings. I checked the log and I see where the detection started but immediately failed with error “commercial detection failed with exit status 7”. I included a snippet from the log below.

What kind of system is the DVR installed on?

Visit http://127.0.0.1:8089/dvr/files/183/comskip.log and paste the last 5-10 lines of output here. (Replace the ip with the ip of your DVR if needed).

I’m using a WD PR2100 NAS. The last 10 lines are:

321:

Strange. Can you SSH in and run this command:

ls -alh /mnt/USB/USB1_c1/Channels\ DVR/Logs/comskip/183/

crisbell · February 9, 2017, 2:34pm

Sure thing…I ran the command and here is what was returned. Also, I recorded a few shows last night and two of them marked the commercial and two didn’t.

What about the output of “mount”

crisbell · February 9, 2017, 6:22pm

I’m sorry, I don’t know what that means. You need me to run another command?

tmm1 · February 9, 2017, 6:23pm

Yes ssh in and type mount

crisbell · February 9, 2017, 7:06pm

this is what i get for “mount”:

Thanks. It appears your external drive is formatted NTFS, and that’s causing some kind of issue. You said it works sometimes but fails others right?

Can you lookup the last few lines from another failure and paste them here too. Are all the failures you see labelled as “exit status 7”?

crisbell · February 9, 2017, 7:50pm

It has been pretty perfect detecting commercials until two nights ago. Yep, they have all been “exit status 7”. I will check the log for another failure and post.

Here are a few lines from another failure.

I have an update. I recorded five shows tonight. Three that were half hour and two that were an hour. All the half hours shows commercials were marked and the hour shows failed. I’m testing two more one hour recordings now to see if they will fail. Will report back.

crisbell · May 16, 2017, 2:51am

@tmm1 What should external drives be formatted to work best with Channels? Using linux on WD PR2100.

TeddyR · May 16, 2017, 5:54am

Probably anything except FAT32. FAT32 has a 2gb per file limit that will be problematic for longer shows.

https://support.wdc.com/knowledgebase/answer.aspx?ID=15124

I would probably use NTFS.

tmm1 · May 16, 2017, 4:24pm

Have you still been having issues with comskip failures?

crisbell · May 16, 2017, 5:43pm

I am, but it’s wasnt a big deal so I didn’t worry about mentioning it. Since it seem to be only affecting me due to my external drive’s formatting. That’s why I was wondering what was the best format.

tmm1 · May 16, 2017, 6:47pm

It seems the NTFS driver on the WD NAS is throwing these strange errors, so probably exFAT would work better.
