Hi there… I have noticed that when i stream over RTSP streams are working OK in my LAN… If i try to access the server from WAN side i have a problem… Then i figured out that the problem lies in UDP traffic… ☹ Is there anyway that i can force wowza to use only TCP and not UDP for streaming? Thank you in advance… PS: I need this for VoD use… ---

Hmm… Can wowza do RTSP/RTP over http? As i understand HTTP is based on TCP… Maybe this could be a solution for me… If Wowza can do this can someone point me how to do it? Thank you in advance… ---

We support all the different variations of RTSP/RTP (RTSP/RTP over UDP, RTSP/RTP interleaved (RTP over TCP) and RTSP/RTP tunneling (over HTTP)). The problem is that it the player that controls the protocol selection not the server. Many players only support RTSP/RTP over UDP. Charlie ---

> How can i do RTSP/RTP tunneling (over HTTP) ? We do support it but I have seen it ever used by the QuickTime player. The player determines the protocol so does the player you are using support it? Charlie ---

Wowza supports RTSP/RTP tunneling (RTSP/RTP over HTTP ala QuickTime), RTSP/RTP interleaved (RTP over TCP) and regular RTSP/RTP over UDP. Chalrie ---

You should still be able to go through NAT, that doesn’t necessarily preclude the use of UDP. -Ian ---

Hmm… That means that if i use an STB behind a NAT router there is no way that i can watch files from my PC over Internet? is this right or wrong!? ---

Hello Charlie. I am sending RTR live stream to wowza. I use a command: vlc -vvv file.avi --sout ‘#transcode{venc=x264{keyint=60,profile=baseline,level=3.0,nocabac},vcodec=x264,vb=150,scale=0.5,acodec=mp4a,ab=96,channels=2,samplerate=48000}:rtp{dst=,port=1935,sdp=rtmp:///test.sdp}’ ForceInterleaved is enabled into MediaCaster block for Wowza application. Stream is playing by VLC too. rtsp://:1935/live/file.sdp is work fine. How I can play stream over HTTP? For example: http://:1935/live/file.sdp ---

Thanks for quick answer. Can wowza restream rtp to stb using http tunneling?
