With UDP / RTP you can send the stream to max.8 Exstreamers directly or also as broadcast or to a multicast address to all Exstreamers in your network (could be 100 or more). RAW TCP is limited to max 8 connections, with HTTP the Instreamer allos maximum 6 connections at the same time. Our favorite mode is RTP streaming (more details in our RTP guide) !! RTP is UDP based which is the best for realtime streaming with lowest latency. With this Exstreamer firmware you can use RAW UDP, RAW TCP, HTTP or RTP. URL = If you have changed the port number on the Instreamer´s “Stream to” entry to anything else than 0 or 80 (e.g to 3333) then you have to use the following URL line : Exstreamer standard firmware The default Port 0 together with “Internet Radio” in the “Stream to” line would mean also port 80.ġ. Streaming / “Stream to” = Internet Radio : 0.0.0.0 : 80īoth are default values. This opens a BRTP listen port where multiple Exstreamers can pull a stream from ! Note, this is only on the first “Stream to” entry available, not on the entries 2-8 !!! Streaming / “Stream to” = RTP : (Exstreamer´s IP): 4444 Īudio / “Bit Reservoir Mode” = kept empty This firmware is downloadable from (under downloads). It´s a dedicated streaming application with enhanced monitoring features and stream backup feature ! This firmware is a special firmware which can run on all Exstreamer platforms. Using the Exstreamer Streaming Client firmware Ī delay of 200 – 250 ms by using MP3 should run in the most stable LANs. In our test lab we have reached by using MP3 a lowest possible delay of 175 ms, lower delays (below 100 ms) are possible by using PCM or G.711. 3,75 seconds plus network delay, which is almost nothing in a local LAN. A higher audio bandwidth fills the buffer faster and causes a lower delay.Ĭalculation example with a 128 kbit stream and a default buffer of 60000 byte:ġ28000 / 8 = 16000 bytes /s 60000 / 16000 = 3,75 s The delay can be from below 200 ms up to serveral seconds, depending from the used audio bandwidth (Codec, frequency/quality) in the Instreamer and the audio buffer (Start Threshold) in the Exstreamer. In the Exstreamer web setup on parameter “Start Threshold” (under Streaming) you can adjust the delay. DHCP is also possible but a fix IP has some advantages. It´s recommended to use the Exstreamer Streaming Client firmware!įirst you always should assign fix IP addresses to each unit. There are different ways to send analog (line-in) audio from a Barix Instreamer over the network to the Barix Exstreamer where your speakers could be connected.Īdditionally to the modes mentioned below, you can send audio from the Instreamer or the Annuncicom to the Exstreamer´s “Priority Ports”, this works in all Exstreamer modes.īelow are shown configuration examples with the Streaming Client firmware and the Standard firmware for the Exstreamer. Or even on the Priority port (if configured).How to configure a Instreamer-Exstreamer audio connection within the same LAN The Exstreamer can receive the ICgraph RTP stream on the normal Streaming URL The ICgraph application is extremely flexible and available for download on the Barix homepage. The ICgraph application is a Java based application for PC (Win, Linux, MAC) which can stream the PC Microphone to configurable targets. In on of the upper entries for the Streaming Linksĭ) via the Barix ICgraph application. configure streaminmg URL of the Streaming Server in the Exstreamer Streaming Client or the Exstreamer M400,.start your streaming server and also your streaming source (e.g.To get it to work please do the following: Now you are able to pull the stream with the Exstreamer from the server. (generates a RTP multicast stream to port number 4444)įor more details please check: to use the VLC Media Player_v19.pdfĬ) HTTP-Server: Please install a Shoutcast or Icecast Streaming server on your PC. then copy the following string to “Edit Options”for RTP Streaming (requires RTP Listen Port on Barix devices):.make sure the “Show more options” check box is marked.there select your audio files (MP3) or your playlist file (m3u).select from VLC menu : MEDIA – Advanced Open File.To stream from a new VLC version to a Barix Exstreamer execute the following steps: In the newer VLC Media player versions you have to copy the OPTION string manually. The following description was tested with VLC Media Player version 1.1.5. The application will create a rtp-stream and send it through your network.ī) VLC Media Player: That´s a very popular audio software which works also with Barix products. A) MP3_RTP_Streamer Application: Please install this java-application on your pc.
