ld-cut issues

[toynbeeidea]

While trying to splice out a clip for #493, I used the following command:

./ld-cut -S 85798 -l 500 -n /run/media/erik/NAS4FreeSync/RTW.ldf /run/media/erik/NAS4FreeSync/rtw-clip.lds

Which gave a message, "ERROR: Seeking failed," and froze until I ctrl-c'd out of it. Not terribly specific.

I kept inching back to find a spot that wouldn't error. Backing up to 85650 gave:

Traceback (most recent call last):
File "/home/erik/github/ld-decode/lddecode/core.py", line 2697, in decodefield

File "/home/erik/github/ld-decode/lddecode/core.py", line 2365, in process

File "/usr/lib/python3.8/site-packages/numba/np/arraymath.py", line 502, in array_min_impl
raise ValueError(MSG)
ValueError: zero-size array to reduction operation minimum which has no identity

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "./ld-cut", line 63, in
startloc = ldd.seek(args.start, args.seek)
File "/home/erik/github/ld-decode/lddecode/core.py", line 3126, in seek

File "/home/erik/github/ld-decode/lddecode/core.py", line 3097, in seek_getframenr

File "/home/erik/github/ld-decode/lddecode/core.py", line 2701, in decodefield
self.internalerrors.append(e)
AttributeError: 'int' object has no attribute 'append'

Backing up to 85649 worked exactly as expected.

Try using -s to move the start point...?

What I'll look at in the morning: If -s is not specified (in ld-decode or -cut), try jumping the same distance. If that fails (typically because it's a clip), try again with -s 0.

(edit: done!)

Sorry, haven't had a chance to mess with the fix yet... will check it out shortly and report back.

Seems to work as expected. Nice.
