[mythtv-users] Help resolving cutlist problem?

Sat Oct 4 19:49:12 UTC 2008

Hi,
    A few months back when I moved to the new QT4 versions of svn head I 
stopped being able to run nuvexport.  It wasn't a big deal at the time 
and I've just now gotten around to messing with it again.  What I've 
found is that I can successfully run nuvexport as long as I don't honor 
the cutlist.  As soon as I do try to use the cutlist, no matter what 
codec I'm using, I will get an output file of the same few frames 
repeating over, and over, and over, and over...  Sound is the same.  
I've attached debug logs - it appears that mythtranscode is correctly 
calculating the size, but once it starts writing to the fifo directory 
it spits out a few frames, then forces a seek back to the beginning.  
I've tried moving the cut point to be at a key frame, to be a non-key 
frame, etc.  All result in the same thing.  Is anybody else having this 
same problem?

Thanks,
Scott Milliken
