[mythtv-users] Commercials are never detected

Mon May 5 17:20:41 UTC 2008

For the sake of completeness, I also ran a commflag job manually on
the slave backend that actually does the recording, instead of running
on the master backend which just provides storage and database (and
runs about half the transcode jobs).   I encountered the same result -
lots and lots of log with no errors reported.  At the end of the job,
breaks were indeed found, in contrast with the initial "automatic"
commflag job claiming no breaks were found.

htpc at htpc:~$ mythcommflag -f 1006_20080505120000.mpg -v all,notimestamp
(snip)
2008-05-05 13:00:04.412 MSqlQuery: UPDATE recorded SET commflagged = 1
WHERE chanid = '1006' AND starttime = '2008-05-05T12:00:00' ;
2008-05-05 13:00:04.424 JobQueue: ChangeJobStatus(397, Finished,
'Finished, 3 break(s) found.')
2008-05-05 13:00:04.424 MSqlQuery: UPDATE jobqueue SET status = 272,
comment = 'Finished, 3 break(s) found.' WHERE id = 397;

When I look at MythWeb it appears that the job was ran and completed fine. I have "All Available Methods" selected and "Strict Commercial Detection" turned off. Out of probably the 50 shows I've recorded so far not one has had a single commercial detected. I tried searching on Google and on this list but I couldn't find anyone with a similar problem. Any ideas?

Oddly, when I hit "z" when playing back a problem recording it says "Not flagged" although when highlighting the show in the recordings section, it has the icon that shows it has been flagged. In mythweb after the the flagging job has run it always says "0 commercial breaks found." I have not tried turning on "Strict Commercial Detection" because I'm under the impression that it typically would find less commercials when thats on (if the flagging was working in the first place). I can try turning it on if that might make a difference.
