[Live-devel] SVC -> AVC

[Sergey G. Kosov]

I tried to do as you advised me. When I just continue to read following
block, I get the error: "StreamPaercer internal error (149997 + 4) 150000)"
I looked the source codes of the StreamPaercer.cpp and as I understand there
is limited block of memory from which I could read.
I suspect that I have to quit the parse function before reading, or reset
this block somehow.

Please help me with a piece of advice.

No.  Because (in your code) you've already read the entire NAL unit (via the
calls to "get1Byte()"), you don't call "skipBytes()" at all. 
Instead, just continue and read/analyze the next NAL unit.
