The file is actually ~/.commercial_cut.rc

I used 'mythcommflag --rebuild' to insert a .VOB from a DVD about 4 months ago. It was on MythTV 0.16 (KnoppMyth R4V5). I think it should still work.

Hey nigel, I tried that and the thing is that I renamed the files after I took them out of the tv directory so I know which ones they were. So after I put them back in and it told me that the file name format is invilad, I tried to make up a name that fits the numbers that the other files have. Then I was able to run myth.rebuilddatabase.pl sucessfully. When I ran mythcommflag --rebuild it came out with this:
and then all the other files were rebuilt sucessfully.
Do you know the file name format that mythtv uses so I can try to come up with a name that it likes?

The numbers in the name are date/time stamps for the start and end of the recording. One thing you could do is to schedule a manual recording which will populate the database with a recording entry. Then replace the recorded nuv file with your orphaned nuv. Then run the mythcommflag --rebuild on that recording. Otherwise, just come up with date/time stamps for the start and end time and use myth.rebuilddatabase.pl to enter it in the database.

I've been trying to get commercial cut to work, but I haven't had any total successes yet.

I am not using knoppmyth so I had to add in the mysql password and change the /myth/tv to /video which is where my recordings are stored.

I am using a PVR-500 and recording using the MPEG-2 PS Stream type. After I manually edit the cutlist to remove all the commercials, I run mythtranscode (which is now linked to commercial_cut) and it creates a new file that seems to have the correct running time and file size. However, when I go to play the file it just gives me a flash of blackness and then sends me back to my list of recordings.

Has anyone else had success with a PVR-500? Might it be the stream type?

Well I got it to work. There are still problems though, it's cutting out the wrong stuff. I think it's cutting a shifted version of my cutlist. At least I know it works though. The odd part is that it only works on the new things that I've recorded. I probably changed somethng in the recording settings.

If it is cutting the wrong bits, it could be the 12/15 frames per index PAL/NTSC issue. You are recording in NTSC right?

If this is your problem, You should be able to edit commercial_cut.c and replace 12 with 15 in a few places.

I asked some PAL people to provide some details of their recordings in the hope that we could auto-detect but no one has responded.

I just had another idea. Comparing the maximum index with the duration, you may be able to detect the difference between 12 and 15 frames per index.

Ah, I am in NTSC! I will try this as soon as I get home!

Scratch that, thanks to the magic of SSH I can do it right from school.

I found 3 instances of the number 12 (and a fourth in an array index which I assume has nothing to do with this problem.)

Can anyone veryify that there are 3 values to change?

Awesome, it works now!

Thanks for the help.

hmmm,

Newest versioSVN pass a job list number to mythtranscode rather than the chanid and start time. So replacing mythtranscode with commercial_cut does not currently work.

It fails with "cant find file /myth/tv/4 " for rather obvious reasons. Is any one got ideas about how to fix this ?

EDIT - Played around with this a bit to force jobqueue.cpp to still output the -c -s options, but
there are a couple of other snags.
1) the new filename format is chanid_starttime.mpg, and so commercial_cut fails to find the file, even though it queries the directory correctly.

2) if you use it on older files that retain the chanid_starttime_endtime.nuv format, then the file is cut, but when put back into the database he basename is kept as the original basename. The newest SVN uses this as the key to access the file, which no longer exists (original file name)

This technically isn't about the commercial cutting program, but I figure I'll ask here in case anyone else has had the same problem.

After I cut the commercials, I want to archive the shows to a DVD.

First I heard that the nuv file is simply a DVD-compatible mpg and all you need to do was rename the file. I tried just renaming the .nuv to .mpg and dvdauthor said it didn't recognize the audio stream.

Then I tried using tcextract to pull out the audio and video into separate files. After I separated them, I remuxed them with mplex and used dvdauthor again. This works (meaning it doesn't give any errors, but gives TONS of warnings), but the file created by mplex has some serious audio issues. The first "uncut" portion plays normally with audio and video synced perfectly. However after the first cutpoint, the audio drops out completely. I've been looking around and apparently MPEG2 has some issues with editing that I wasn't aware of.

The original .nuv file's audio and video are synced when I play them in mythtv, so something must be happening during the demux/remux stage that is throwing them out of whack.

Does anyone know how to get the audio/video re-synchronized after cutting commercials? Or alternatively, does anyone know how to get dvdauthor to accept the renamed .nuv files?
