Hi Gilles,

How were you extracting the NALU's from the frames provided by the 
encoder? Were you using the H264VideoFramer class?


I'm aware that we're not going to see anything from TI and their SDK is 
still an 'alpha' release.

Ross, I appreciate the support you provide, I hope my experiences can 
help others and make the software better.
