It’s not just “not really” a crash; it’s not even close to a crash.  A C++ 
exception is *not* an error of any kind; it’s simply a part of the C++ 
language, just like an “if” or a “switch” statement.  Our code uses this (C++ 
language exception) to handle parsing of stream data (in your case, H.264 
video).

“Nothing to see here; move along.”

Huh?  I’ve already told you that - when you’re feeding H.264 data to a 
downstream “H264VideoStreamFramer” - this data MUST have a start code in front 
of each NAL unit.  So why are you arguing about this?  I’ve already told you 
what needs to be done.


(If, instead, your upstream object (“OCVFileSource”) were to deliver *discrete* 
NAL units - i.e., one at a time, for each call to “doGetNextFrame” - then you 
would feed it instead to a “H264VideoStreamDiscreteFramer”, and each NAL unit 
would *not* begin with a ‘start code’.  But because you’re using “x264”, which 
(I assume) delivers groups of NAL units, each prepended with a start code, then 
feeding this to a “H264VideoStreamFramer” (with the start codes) is the right 
thing to do.)
