    Default is this multicast or unicast?

    i hired someone to convert multicast streams from lan into unicast so that i can see the streams from a remote location using the internet. the stream is really choppy and i was given this address:

    http://XXX.XXX.XXX.XXX:1935/udp/224.1.5.4:4000

    is it possible for unicast streams still have the "/udp/224.1.5.4:4000" part? or i'm still getting udp multicast over the internet, hence i have bad quality streams?

    Choppy playback is usually the result of a stream bitrate higher than client bandwidth, the throughput from Wowza to that client. Try a lower bitrate.

    The "224.1.5.4:4000", which is the stream name part of that url, is unusual but can work if it is an alias. An mpegts or multicast source is usually contained in a .stream file, a text file in the /content folder containing that udp url. For example a file /content/mpegts.stream that contained the udp url of the stream. Then you use mpegts.stream as the stream name instead of a URL. This is the basic mpeg-ts guide

    The http url you show is not a complete playback URL that is supported by Wowza. For iOS playback it would have to be http://xxx.xxx.xxx.xxx:1935/udp/224.1.5.4:4000/playlist.m3u8 or Flash HTTP http://xxx.xxx.xxx.xxx:1935/udp/224.1.5.4:4000/manifest.f4m

    Wowza's output in this case is unicast, whether the source is multicast or not.

    That looks like a typical udpxy address - and is unicast
