ffmbc 0.6rc1 -timecode and -timecode_frame_start in the same command ine

[GoogleCodeExporter]

Still got the same error on 0.6-rc2.

Same results with both static and dynamic builds on Ubuntu 10.04 LTS, dynamic 
build on OS-X, and static build for Win32. Examples of all three below.

From some of the failures we're getting, it looks like command line parsing is 
very fragile in FFmbc 0.6.

A colleague has run valgrind over that CLI a few times with running a dynamic 
build of ffmbc-0.6-rc2 with symbols.

He says "I did notice that you get slightly different output when run without 
redirecting and with, and this error, or round here, seems to be the point of 
inflection and also rather more serious looking than a lot of the others:

[NULL @ 0x4a46750] [Eval @ 0xbebe1dac] Undefined constant or missing '(' in '^N'
==17458== Conditional jump or move depends on uninitialised value(s)
==17458==    at 0x4027AE8: __strcpy_chk (mc_replace_strmem.c:757)
==17458==    by 0x85E1B7E: av_log (log.c:143)

==17458==    by 0x85E05A2: parse_factor (eval.c:323)

I've also tried running the CLI without the -loglevel debug, and you get a 
similar sort of barf, but with a different stack:

[NULL @ 0x4a46750] Unable to parse option value "^L"
==17674== Conditional jump or move depends on uninitialised value(s)

==17674==    by 0x808B3E9: main (ffmbc.c:4857)

The second one looks a little more useful to me."

I have the complete outputs from the valgrind runs if that is more useful.
