Unable to stream MP3

[samfrog]

I want to stream a MP3 file using my custom RTSP server with VLC media player. However, I am getting a list of 'emulated startcode' in the VLC log.

Here are the sequences:
1. I wrote a UDP program that reads a MP3 file and sends the MP3 frames by frames with MP3 header included to a data structure.
2. I issued a vlc rtsp://x.x.x.x:554/Test via VLC media player
3. My RTSP server receives the RTSP requests and replies with the appropriate responses.

The SDP is as follows:

RTSP/1.0 200 OK\r\n
Content-type: application/sdp\r\n
Server: VLC Server\r\n
Content-Length: 181\r\n
CSeq: 2\r\n
Cache-Control: no-cache\r\n
\r\n

v=0\r\n
o=- 556165832000 2 IN IP4 10.73.50.98\r\n
c=IN IP4 0.0.0.0\r\n
t=0 0\r\n
a=tool:vlc 1.0.5\r\n
m=audio 0 RTP/AVP 14\r\n
a=rtpmap:14 MPA/44100\r\n
a=control:rtsp://x.x.x.x:554/Test/trackID=0\r\n

4. At PLAY, my RTSP server reads the MP3 frame from the data structure and encapsulated with RTP and sends it to the port that client requests.

However, the VLC media player is having trouble processing it. Does anyone know how to fix it?

The VLC log is:

[Rémi Denis-Courmont]

Your server is buggy. From the error messages, I would guess you are not formatting the MPA payload of your RTP packets correctly.

[samfrog]

What are the sequences of formatting the MPA payload?

Say the frame is 522 bytes, How do I packetize it to stream it to VLC for playback ?

I am doing the following:

12 bytes of RTP + 4 bytes of MPEG Audio-specific header (RFC2038) + 4 bytes of TS header + 184 bytes MPA payload + 4 bytes of TS header + 184 bytes of MPA payload + 4 bytes of TS header + 184 bytes of MPA (only the first 154 bytes are from the left over MPA payload, the 30 left over bytes set to 0)
