Thread: nuvexport fails sometimes - SOLVED

Any idea why nuvexport has a fairly high failure rate for me? I guess actually it's probably not nuvexport, but one of the programs it calls. I've hacked together the command line options for /usr/bin/mpeg2cut and it fails with the same error messages. Here's an example:

Code:

mpeg2cut /second/mythtv/1037_20051017105900_20051017120000.nuv /second/media/ds9..resurrection-needsEncoding.mpg 109590 "-3120 3433-10268 16604-26538 32578-46354 53145-67422 73762-91195 97249-"

Here's lines #159 - #162 of mpeg2cut:

Any ideas?

I found an email thread about it here http://mythtv.org/pipermail/mythtv-u...ay/090437.html

One thing I've noticed that I don't know if it's significant or not. I input the last frame as 107835 and my cut list ends with "93750-". My .cut file ends with

Code:

Start : 93750
Size : 14086
Ref : 0

If you add 93750 and 14086 you get 107836 which is 1 more than 107835 (the last frame). Is this significant?

Just peering into /usr/bin/mpeg2cut, line 139 of version 178 is

Code:

END=${LASTFRAME}

Then line 141 is

Code:

LENGTH=$((${END} - ${START} + 1))

This appears to be what produces this "end + 1" problem. However, changing line 139 to

Code:

END=$(( ${LASTFRAME} - 1 ))

... didn't really seem to help. It still had start 93750 and size 14086.

I stand corrected. Once I edited /usr/bin/mpeg2cut on the same machine I was executing it on it did appear to fix this problem.
