How can I broadcast an mp3 file using rtsp?
The open source VideoLAN project will do RTSP.

I have a pcap file that contains rtp data received and sent over the network. In wireshark I use follow udp stream to access raw data for source and destination. Then I save source and destinations files separately. How can I extract audio/video data from these files and convert them to a playable file?
These links provide the info you need:
Cisco community - use audacity
Wireshark wiki - rtpdump
I have created an RTP stream with ffmpeg and made the SDP file from what it printed out.
I can connect ffplay to the stream by reading the sdp file.
What is the correct url to give to QMediaContent to connect it to a RTP stream by giving it a local / remote SDP file?
I want to be able to create an application that can read and publish an RTMP stream.
Using OpenCV i could read rtp due to it's ffmpeg backend.
Stream video from ffmpeg and capture with OpenCV
C++ RTMP is another possibility, but this is an RTMP server so it mainly requests and sends files. Although open source, i am unsure how to build or integrate this into a Visual Studio application in such a way as to make the function calls available to my project.
OTher sources indicate that OpenCV's RTSP isn't great.

How can you run a streaming server, such as RTMP C++ and get the raw data out. OpenCV can encode and decode image data for streaming, but how can you link the two?
Could a C++ application pipe a stream together? How could i interface with that stream to send it more images? Also, for receiving images?
Regards,
cRMTPServer and LibRTMP works well.
I'm working on an application where I want to stream h264 over mpegts
to a rtmp server (FMS, C++ RTMP Server, Wowza). I'm looking at the
output-example.c of libav. I stripped all the audio for now to keep it
simple.
I'm using this code as a test (not working):

What am I doing wrong there?
Thanks
I've compiled with VS the live555 source code, and it works just fine if I try to stream locally a file
e.g.
Command Line:
live555.exe myfile.mp3
VLC Connection String
rtsp://169.254.1.231:8554/myfile.mp3
but if I try to stream it over the internet, VLC communicates with live555, but live555 won't send data to him
Command Line
live555.exe myfile.mp3
VLC Connection String
rtsp://80.223.43.123:8554/myfile.mp3
I've already forwarded the 8554 port (both tcp/udp) and tried to disable my firewall but this doesn't solve.
How is that?
To troubleshoot:
Are you streaming RTP over RTSP: have you checked the "Use RTP over RTSP (TCP)" option in VLC? You can check this in VLC under the preferences: input/codecs->Demuxers->RTP/RTSP. You can try to see if this solves the problem in which case it could be that UDP is blocked.
You speak of forwarding. Do you mean port forwarding from one machine to the RTSP server? if so-> if you are not doing RTP over RTSP, then you would also need to forward the ports for the media which is not the same as the RTSP port (554 or 8554). These ports are exchanged during the RTSP SETUP. If you do RTP over RTSP the media is interleaved over 554 or 8554 and you don't have to worry about this.
Also, another good debugging tool is the live555 openRTSP application. You can run it from the command line and specify "-t" for RTP over RTSP, which is basically what the VLC option does. You can specify "-T" for HTTP tunneling, etc and it allows you to write captured media packets to file, etc.
