We are trying to setup the RTSP Authentication. I’ve setup the public.password file for RTP authentication also we’ve configured the application RTP/Authentication/PlayMethod to digest in the application.xml. Everything goes well after configuration, the stream is protected with the username. Except when I am trying to use VLC to connect, it ask me twice for username and password on every request. any idea? By the way, I am using the mediacache in this application. The log in console shows the following, it seems that the VLC player is trying to connect twice…:- INFO stream stop c1/1/iphone\_sample.mp4 - INFO stream destroy c1/1/iphone\_sample.mp4 - INFO rtsp disconnect 1152285236 - INFO rtsp connect 316413612 - INFO stream create - - INFO rtsp describe 316413612 - INFO server comment - RTPUDPTransport.bind[bbvdoapps/_definst_]: in:0.0.0.0/0.0.0.0:6974 out:/10.10.10.8:54720 INFO server comment - RTPUDPTransport.bind[bbvdoapps/_definst_]: in:0.0.0.0/0.0.0.0:6975 out:/10.10.10.8:54721 INFO server comment - RTPUDPTransport.bind[bbvdoapps/_definst_]: in:0.0.0.0/0.0.0.0:6976 out:/10.10.10.8:54722 INFO server comment - RTPUDPTransport.bind[bbvdoapps/_definst_]: in:0.0.0.0/0.0.0.0:6977 out:/10.10.10.8:54723 INFO stream play c1/1/iphone\_sample.mp4 - INFO rtsp play 316413612 - INFO server comment - RTPUDPTransport.unbind[bbvdoapps/_definst_]: 0.0.0.0/0.0.0.0:6974 sent:180 recv:0 INFO server comment - RTPUDPTransport.unbind[bbvdoapps/_definst_]: 0.0.0.0/0.0.0.0:6975 sent:4 recv:0 INFO server comment - RTPUDPTransport.unbind[bbvdoapps/_definst_]: 0.0.0.0/0.0.0.0:6976 sent:598 recv:0 INFO server comment - RTPUDPTransport.unbind[bbvdoapps/_definst_]: 0.0.0.0/0.0.0.0:6977 sent:4 recv:0 INFO stream stop c1/1/iphone\_sample.mp4 - INFO stream destroy c1/1/iphone\_sample.mp4 - INFO rtsp disconnect 316413612 - INFO rtsp connect 727524933 - INFO stream create - - INFO rtsp describe 727524933 - INFO stream play c1/1/iphone\_sample.mp4 - INFO rtsp play 727524933 - INFO stream stop c1/1/iphone\_sample.mp4 - INFO stream destroy c1/1/iphone\_sample.mp4 - INFO rtsp disconnect 727524933 - ---

What version of Wowza and VLC? Upgrading is always a good idea. Try playing the RTSP stream in VLC from a different computer. I have tested this on Wowza 3.0.3.10 build995 with VLC 1.1.11 and it only asks for the password one time. ```auto INFO rtsp connect 975027157 - INFO stream create - - INFO rtsp describe 975027157 - INFO server comment - RTPUDPTransport.bind[live/_definst_]: in:0.0.0.0/0.0.0.0:6 970 out:/127.0.0.1:58550 INFO server comment - RTPUDPTransport.bind[live/_definst_]: in:0.0.0.0/0.0.0.0:6 971 out:/127.0.0.1:58551 INFO server comment - RTPUDPTransport.bind[live/_definst_]: in:0.0.0.0/0.0.0.0:6 972 out:/127.0.0.1:58558 INFO server comment - RTPUDPTransport.bind[live/_definst_]: in:0.0.0.0/0.0.0.0:6 973 out:/127.0.0.1:58559 INFO stream play myStream - INFO rtsp play 975027157 - INFO server comment - LiveStreamPacketizerSmoothStreaming.addFragment[live/_defi nst_/myStream]: Add chunk: type:video id:9 count:30 duration:3675 INFO server comment - UDPTransport.firstPacket: bind:0.0.0.0/0.0.0.0:6971 msg:/1 27.0.0.1:58551 INFO server comment - UDPTransport.firstPacket: bind:0.0.0.0/0.0.0.0:6973 msg:/1 27.0.0.1:58559 ``` Note: Haven’t tried it with MediaCache (yet). ---

VLC will failover to TCP if UDP is blocked. You can force it to use TCP initially: [https://www.wowza.com/docs/how-to-configure-vlc-media-player-for-rtsp-rtp-playback-rtsp-rtp-interleaved-and-tuning](https://www.wowza.com/docs/how-to-configure-vlc-media-player-for-rtsp-rtp-playback-rtsp-rtp-interleaved-and-tuning) Or you can unblock UDP ports (0-65535) possibly in your firewall, or other point in your network.

my version is Wowza Media Server 3 Perpetual Edition 3.0.3 build882 and VLC is 1.1.11. also, wowza server and vlc are different computer it is okay with ```auto rtsp://username:password@ip:port/mediacache/_definst_/mp4:http/path1/filename.mp4 ``` but still twice without username:password in URL. the performance on video start time is degrading on the twice handshaking… ☹ need helps! ---
