Some notes:
1. A cutlist starting with 0 doenst work
2. With a cutlist I ran out of video buffers. I tried cranking
line 162 from 500 to 10000 and it didnt help.
3. The encoded video (with and without -l ) is very choppy. With
no cutlist my file shrank from 1.2GB to 1GB. Not sure where the 200MB went
but it might be needed. Is it DVD NAV sequences?
4. I noticed this message in my nuv.log "Found 0 bytes of garbage
data before header".
I put my nuv.log up on line (you know where) if you want it.

Re: [mythtv] [PATCH] MPEG2->MPEG2 commercial cut (myth patch)
Okay, here is a minor update. It replaces the old patch (apply it to
clean CVS)
Changes:
Allow upto 500 buffers for audio/video deskew.
Support padding frames in video streams. This is apparently a
manifestation of a libavformat bug, but this is a reasonable fix until
that has been sorted.
Cutlists should work a bit better. Support for cutlists beginning at
frame '0'
You can specify the cutlist while using the '-i' switch on the command
line as:
mythtranscode -i file -l "start-dest start-dest ..."
(the -l parameter MUST occur after the -i paramter). a list for the '-l'
switch is only supported when '-i' is specified. This should facilitate
debug.
The following are known issues that still need resolution:
We need to rebuild the keyframe index once the transcoding is done.
The new code needs to check for changes to the DB and recover.
I appreciate the bug reports I've gotten so far, and would appreciate
more from any other brave souls.
.Geoff
