[streaming] RTSP Compatibility Issue

[Wang He-VHJ374]

Hi All
 
I have a very specific issue about HelixClient,VLC,RTSP.
1) I can create connection from Darwin Server and Helix Client, the
protocol date captured:
...
 
SETUP rtsp://10.193.50.53:554/H264_AAC_60kbps.3gp/trackID=65335 RTSP/1.0
CSeq: 3
Transport: RTP/AVP;UNICAST;client_port=6970-6971;mode=play
User-Agent: RealMedia Player (HelixDNAClient)/10.0.0.2587
(linux-2.2-libc6-gcc34-arm11)
 
RTSP/1.0 200 OK
Server: DSS/5.5.4 (Build/489.13; Platform/Linux; Release/Darwin; )

[Wang He] When Video SETUP/resp finish, Audio SETUP followed.
 
2) I cannot create connection from VLC Server and Helix Client, the
protocol date capatured:
...
 
SETUP rtsp://192.168.16.1:1234/test.sdp/trackID=0 RTSP/1.0
CSeq: 3
Transport: RTP/AVP;unicast;client_port=6970-6971;mode=play
User-Agent: RealMedia Player (HelixDNAClient)/10.0.0.2587
(linux-2.2-libc6-gcc34-arm11)
 
RTSP/1.0 200 OK
Transport: RTP/AVP/UDP;client_port=6970-6971
Server: VLC Server
Content-Length: 0
Cseq: 3
Cache-Control: no-cache
Session: 18467
[Wang He] When Video SETUP finished, Helix Player TEARDOWN the session.
The reason maybe: some protocol field&value of SETUP response is need by
Helix, but VLC didn't provide.
 
TEARDOWN rtsp://192.168.16.1:1234/ RTSP/1.0
CSeq: 4

3) Do you guys have any idea about this issue? Is my analysis correct?
or anything else?
do you have any idea to fix this issue?
 
Thanks!
