Problem with publishing rtmp stream to FMS with librtmp - rtmp

Question

I'm trying to get video from the webcam and get it encoded and then publish the stream to FMS. and now I'am having a problem when I try to publish RTMP stream to the FMS with librtmp.
My code:
char uri[]="rtmp://127.0.0.1/live/bolton";
r= RTMP_Alloc();
RTMP_Init(r);
RTMP_SetupURL(r, (char*)uri);
r->Link.lFlags |= RTMP_LF_LIVE;
r->Link.lFlags |= RTMP_LF_BUFX;
RTMP_EnableWrite(r);
//RTMP_SetBufferMS(r, bufferTime);
RTMP_Connect(r, NULL);
RTMP_ConnectStream(r,0);
And log:

ERROR: RTMP_ReadPacket, failed to read RTMP packet header
DEBUG2: RTMP_SendPacket: fd=-1, size=307
It seems that RTMP_connect connected correctly, but failes in the function RTMP_ConnectStream, I'm not familiar with the rtmp connect sequence, and it's killing me.
What should I do to find the problems, Thanks very much!

Answer 1

I'm dealing with the same problem, but using librtmp with ffmpeg. If you look in the function RTMP_ReadPacket(), you'll see the error is thrown when trying to read the packet header with the method ReadN():
int
RTMP_ReadPacket(RTMP *r, RTMPPacket *packet)
{
uint8_t hbuf[RTMP_MAX_HEADER_SIZE] = { 0 };
char *header = (char *)hbuf;
int nSize, hSize, nToRead, nChunk;
int didAlloc = FALSE;
RTMP_Log(RTMP_LOGDEBUG2, "%s: fd=%d", __FUNCTION__, r->m_sb.sb_socket);
if (ReadN(r, (char *)hbuf, 1) == 0)
{
RTMP_Log(RTMP_LOGERROR, "%s, failed to read RTMP packet header", __FUNCTION__);
return FALSE;
}
That error only throws if the ReadN returns a 0. I haven't figured out on my end why that's happening yet, though.

I got the same issue in the Visual studio.
It turned out that in the debug mode,librtmp set some handshake value 0 instead of generating random data.
//handshake.h
/* generate random data */
#ifdef _DEBUG
memset(serversig+8, 0, RTMP_SIG_SIZE-8);
#else
ip = (int32_t *)(serversig+8);
for (i = 2; i < RTMP_SIG_SIZE/4; i++)
*ip++ = rand();
#endif
Just make sure generating random data.
