Hello
Thank you very much for the response i tried to do what you asked me on
your last email but i am a bit confused so please tell me if i
understood well your response any more detailed code will help us so
much so don't hesitate if it is easy for you to give me an example for
one camera for something that could work and i will begin with it to
understand and develop with live555 and we will be happy to get a
solution to our problem by using live555 :
Our cameras :
====CAMERA 1
================================================================
My camera stream to be converted is :
rtsp://192.168.50.41:8601/wxHdSdiStreaming/2?videoCodecType=H.264
My conversion to Transport stream
My converted stream output : rtp://192.168.50.22:5041
==============================================================================
====CAMERA 2
================================================================
My camera stream to be converted is :
rtsp://192.168.50.42:8601/wxHdSdiStreaming/2?videoCodecType=H.264
My conversion to Transport stream
My converted stream output : rtp://192.168.50.22:5042
==============================================================================
.
.
.
====CAMERA 8
=================================================================
My second camera Stream to be converted :
rtsp://192.168.50.48:8601/wxHdSdiStreaming/2?videoCodecType=H.264
My conversion to Transport stream
My converted stream output : rtp://192.168.50.22:5048
===============================================================================
On ?testH264VideoToTransportStream.cpp?
1/ Change inputFileName from ?in.264? to ?stdin?, and
2/ Change outputFileName from ?out.ts? to ?stdout?.
==========================================================
Results : do i have to put stdin definition or really "stdin" like i did
in the following code?
==testH264VideoToTransportStream.cpp======================
#include "liveMedia.hh"
#include "BasicUsageEnvironment.hh"
char const* inputFileName = "stdin";
char const* outputFileName = "stdout";
==========================================================
On ?testMPEG2TransportStream.cpp?
3/ Change inputFileName from ?test.ts? to ?stdin?, and
4/ Change destinationAddressStr and rtpPortNum from built-in constants to
command-line arguments.
==testMPEG2TransportStream.cpp==============================
UsageEnvironment* env;
char const* inputFileName = "stdin";
FramedSource* videoSource;
RTPSink* videoSink;
void play(); // forward
int main(int argc, char** argv) {
// Begin by setting up our usage environment:
TaskScheduler* scheduler = BasicTaskScheduler::createNew();
env = BasicUsageEnvironment::createNew(*scheduler);
// Create 'groupsocks' for RTP and RTCP:
char const* destinationAddressStr
#ifdef USE_SSM
= "232.255.42.42";
#else
= "239.255.42.42";
// Note: This is a multicast address. If you wish to stream using
// unicast instead, then replace this string with the unicast address
// of the (single) destination. (You may also need to make a similar
// change to the receiver program.)
#endif
const unsigned short rtpPortNum = argv[6] ; //Server PORT NUM to send
the stream it does change for each caméra 5040 to 5048 for 9 caméras
const unsigned short rtcpPortNum = 8601; //caméra port Num ( doesn't
change from a caméra to an other one, only the ip address does change )
const unsigned char ttl = 3; // low, in case routers don't admin scope
==========================================================
Commande line :
openRTSP -v rtsp://192.168.50.41:8601/wxHdSdiStreaming/2?videoCodecType=H.264 |
testH264VideoToTransportStream | testMPEG2TransportStreamer 192.168.50.22 5041 &
openRTSP -v rtsp://192.168.50.42:8601/wxHdSdiStreaming/2?videoCodecType=H.264 |
testH264VideoToTransportStream | testMPEG2TransportStreamer 192.168.50.22 5042 &
openRTSP -v rtsp://192.168.50.43:8601/wxHdSdiStreaming/2?videoCodecType=H.264 |
testH264VideoToTransportStream | testMPEG2TransportStreamer 192.168.50.22 5043 &
..... &
openRTSP -v rtsp://192.168.50.48:8601/wxHdSdiStreaming/2?videoCodecType=H.264 |
testH264VideoToTransportStream | testMPEG2TransportStreamer 192.168.50.22 5048
do i have to change this : ifdef USE_SSM= "232.255.42.42"; ?
Thank you in advance

I installed Live555 as discribed in your response but i need a commade ligne
wich allow me to convert live streaming from multiple cameras : i have
RTSP_Stream and a client who need mpegts stream format.
The need that we have somthing like this for example : OpenRTSP
<RTSP_STREM_FROM_CAMERA_SERVER> Convert_RTSP_STREM_TO_TS
<Client_RTP_ADDRESS_:_CLIENT_PORT>
Can i do this with live555 tools?
Yes. The easiest way to do this is to modify the
?testH264VideoToTransportStream.cpp? code to:
1/ Change inputFileName from ?in.264? to ?stdin?, and
2/ Change outputFileName from ?out.ts? to ?stdout?.
Then modify the ?testMPEG2TransportStreamer.cpp? code to:
3/ Change inputFileName from ?test.ts? to ?stdin?, and
4/ Change destinationAddressStr and rtpPortNum from built-in constants to
command-line arguments.
Then run, for each camera:
openRTSP -v camera-rtsp-url | your-modified-testH264VideoToTransportStream
| your-modified-testMPEG2TransportStreamer client-rtp-address client-rtp-port &
I.e., for each camera, you run ?openRTSP? on it, piping its H.264 video output
to (your modified) ?testH264VideoToTransportStream?, then piping the Transport
Stream output of that to (your modified) ?testMPEG2TransportStreamer?.
