[mythtv-users] Commerical Marking Problem

Sun Mar 18 17:30:34 UTC 2007

I've been totally unsuccessful marking commercials in imported mpeg2's. 
So as a test I took one of the internal mpg's in /mnt/store that had 
been recorded and successfully marked by myth, copied it, imported the 
copy and tried marking it manually. It failed. Looking for suggestions, 
but here are the details:

Here is the procedure I used:

cp /mnt/store/1921_20070312200000.mpg /mnt/store/test.mpg
myth.rebuilddatabase.pl  --try_default
mythcommflag -f /mnt/store/1921_20070318113805.mpg

The rebuilddatabse runs mythcommflag itself, but it specifically does it 
with the "--rebuild" flag which causes it to not flag commercials. 
That's why I run it a second time to flag them.

As far as the output from the two rebuilds, it follows. The first is 
uneventful, the second is worrisome.
