Hi Ross,
Even if I have not identify what's wrong with the GET_PARAMETER response sent
by the camera, I confirmed that your modification fix the problem.
Thanks,
Michel.

Objet : Re: [Live-devel] SEGV handling GET_PARAMETER response.
In this context we are in RTSPClient.cpp around 1555 :
// If we saw a "Content-Length:" header, then make sure that we have the
amount of data that it specified:
unsigned bodyOffset = nextLineStart - headerDataCopy;
bodyStart = &fResponseBuffer[bodyOffset];
numBodyBytes = fResponseBytesAlreadySeen - bodyOffset;
if (contentLength > numBodyBytes) {
Gdb says that nextLineStart is NULL, bodyOffset is a big number, and finally
bodyStart point a non allocated memory (that raise a SEGV).
Do you think if is possible to add check nextLineStart before using it :
Instead, please replace the line
unsigned bodyOffset = nextLineStart - headerDataCopy;
with
unsigned bodyOffset = nextLineStart == NULL ?
fResponseBytesAlreadySeen : nextLineStart - headerDataCopy;
If you still have a problem after this change, please let me know. (Otherwise
I'll make that change in the next release of the software.)
