I understand that the exception is coming from the browser. I have traced
it back to a profile-level-id that the browser
cannot handle. I believe that value is coming from (or through) your
software.
I think it is likely coming from liveMedia/H264RTPSink.cpp. What I have
not yet figured out is are you generating the
SDP in live555ProxyServer or are you just passing something through that
the end device sent to you.
u_int32_t profileLevelId = (spsWEB[1]<<16) | (spsWEB[2]<<8) | spsWEB[3];
delete[] spsWEB;
char* sps_base64 = base64Encode((char*)sps, spsSize);
char* pps_base64 = base64Encode((char*)pps, ppsSize);
char const* fmtpFmt =
"a=fmtp:%d packetization-mode=1"
";profile-level-id=%06X"
";sprop-parameter-sets=%s,%s\r\n";
unsigned fmtpFmtSize = strlen(fmtpFmt)
+ 3 /* max char len */
+ 6 /* 3 bytes in hex */
+ strlen(sps_base64) + strlen(pps_base64);
char* fmtp = new char[fmtpFmtSize];
sprintf(fmtp, fmtpFmt,
rtpPayloadType(),
profileLevelId,
sps_base64, pps_base64);
