[Live-devel] Multiple NALUs concatenated together in one afterGettingFrame

[Deanna Earley]

Simply put, a single call to afterGettingFrame in my file sink is receiving a single large "frame" that actually consists of an SPS, PPS, and the I frame in one single byte stream with no prefix or separator between them.
https://dl.dropboxusercontent.com/u/2931731/Bugs/largesps.dat
That is dumped, untouched from the afterGettingFrame callback

Is this likely to be a misparsing of the data in liveMedia or the data as it is received, raw from the camera?
(I'm aware that the H.264 over RTP spec says no prefix but I can't see anything about between frames.)

This is rare (once a week) and the camera is unusual in that it sends an SPS and PPS with every I frame.

Thanks.

I'm having a very hard time understanding exactly what problem you're having.  In particular:

It's missing the H.264 prefixes between NALUs and joined them together in one afterGettingFrame call

What is "It"?  I.e., where is this data coming from?  I.e., are you a client, a server, a proxy server, or what?  Exactly what are you trying to do?

Please be specific about what you are trying to do, where you are seeing a crash, and how our code might possibly be involved.
