[Ssc-dev] ffmpeg crashes with redact plugin

[Andrew Senior]

Sorry about these crashes guys. I was building against head of ffmpeg, but
also 0.8.something release. The head is necessary for writing out two
streams at once (there's a new flag --filtercomplex or somesuch), but I
haven't got that working without a memory leak. IIRC the filter worked with
both builds if you only try to save one output. (In the latest version I
was focussing on saving the redacted video rather than the data needed for
unredaction.

Both crashes appear not to be actually in the redaction filter, but are no
doubt because of some memory corruption caused by it.
It's not clear from these dumps if it crashes on the first frame or part
way through- are these just indicative of memory leaks consuming all the
RAM?
I will try to look tonight, but I'm away and offline most of next week.

Andrew
